In Melbourne’s established inner east, the qualities that define a traditional house, width, height, and access to open ground, are increasingly difficult to replicate in new residential developments. Larger landholdings are scarce, and with them, the ability to create apartments that extend beyond compact, internalised layouts.&nbsp;

In <a href="https://www.apartments.com.au/developments/kew-vic-3101">Kew</a>, where the residential fabric is shaped by generous setbacks and mature tree canopies, that tension is especially visible.

<a href="https://www.apartments.com.au/developers/ricdanic-investments-pty-ltd">Ricdanic</a>&nbsp;is bringing forward a boutique collection of just 13 residences across two buildings at 9–11 Wimba Avenue, Kew. Comprising six homes at No.9 and seven at No.11, the project sits on a quiet, tree-lined street just off Cotham Road.&nbsp;

Each apartment has been planned with a level of independence more commonly associated with standalone dwellings, balancing privacy with the efficiencies of apartment living.

Architect Chris Idle, who has been practising for over two decades, says projects like this don’t come along often.

“There are very few opportunities to do these kinds of developments in leafy, established suburbs,” he explains. “To get this level of amenity, natural light, and architectural freedom in such a setting is extremely rare.”

[smartcode_project:default project_id=140755 project_image_fid=366267]

The internal planning begins with width. Living areas extend beyond five metres, allowing furniture, circulation, and glazing to sit comfortably within the same zone without compression. Ceiling heights shift from three metres through to five metres in select areas, changing the sense of scale as you move through the apartment. These proportions are paired with double-glazed windows and fully electric systems, balancing volume with performance, supported by a 7.2 NatHERS energy rating.&nbsp;

From the main living space, the apartments open directly outward. Large sliding doors connect to private gardens averaging 125 square metres, with some residences also incorporating balconies of around 60 square metres. Rather than acting as secondary outdoor zones, these areas sit flush with the internal floor level, extending the usable footprint of the home and allowing for multiple modes of use, whether for quiet daily routines or larger gatherings.&nbsp;

The landscape, led by <a href="https://www.apartments.com.au/landscape-architect/john-patrick-landscape-architects">John Patrick</a>, reinforces this relationship. Across the site, 23 different plant species have been introduced, including a mix of native and established varieties, arranged to maintain privacy while preserving sightlines and light access. Gardens are not treated as decorative buffers but as functional extensions of the apartments, shaped to accommodate movement, seating, and informal use over time.&nbsp;

[smartcode_project:default project_id=140755 project_image_fid=366265]

Architecturally, the project draws from Kew’s historic residential language. Handmade bricks by Krause define the exterior, grounding the buildings within the material palette of the suburb, while interior finishes, stone, timber flooring, and restrained detailing, continue this approach internally. Architect Chris Idle describes the intent as long-term rather than stylistic: “We wanted it to feel timeless.”&nbsp;

This emphasis on durability extends to how the buildings are accessed and secured. Entry is managed through keyless systems, with a double-gated basement incorporating number plate recognition for vehicle access. Each residence is paired with a private lock-up garage accommodating two to three cars, alongside storage, while all entry points are monitored continuously. These measures sit alongside EV readiness and fully electric infrastructure, aligning the project’s operational systems with its long-term design outlook.&nbsp;

The setting remains central to how the development is experienced. Located within walking distance of Kew Junction and close to established schools including Carey Grammar and Xavier College, the address benefits from existing infrastructure while maintaining a residential quietness that is increasingly difficult to find at this scale.&nbsp;

Construction is being delivered by <a href="https://www.apartments.com.au/builders/sinjen">Sinjen</a>, with a 10-year structural guarantee, with completion targeted for mid-2027.

High-end Sydney developer&nbsp;<a href="https://www.apartments.com.au/developers/abadeen-group">Abadeen</a> has secured approval for one of its latest Mosman projects, one of the first developments approved by Mosman Council under the NSW Government’s Low and Mid-Rise Housing Policy.

The approval represents an important step in delivering well-considered housing next to established village locations on Sydney’s Lower North Shore, in line with the intent of the Low and Mid-Rise zoning framework. 
&nbsp; 
There are currently 13 other sites lodged within Mosman Council under the policy, with <a href="https://www.apartments.com.au/new-apartments/27-29-heydon-street-mosman-nsw-2088">Heydon Street</a> among the first to receive development consent. 
&nbsp; 
Abadeen Founder and Executive Chairman Justin Brown said the project reflects a considered and appropriate response to its planning context. 
&nbsp; 
“This approval demonstrates how carefully considered, design-led development can align with the objectives of the Low and Mid-Rise Housing Policy," Brown said.

"The scheme has been designed to respond sensitively to its village setting, with a built form, scale and level of amenity appropriate to its local context. The determination reflects a balanced and considered planning outcome, with Council recognising the capacity for this site to accommodate additional housing within a well-located and established precinct.”

<img alt="Abadeen secures first approval under low and mid-rise housing policy for Heydon Street, Mosman" data-entity-type="file" data-entity-uuid="92811ce3-02e8-44fc-996e-c61ae039bd3e" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Heydon%20Street%20Aerial.jpg?VersionId=ZHJVuWQT64QcdrFJx963pFWFzTX7lI2I" />

The Heydon Street approval followed extensive consultation with Mosman Council, with Abadeen working closely with Council throughout the assessment process.

The approved scheme comprises 27 residences, with only four per floor, creating a low-density living environment. The building will include four half-floor penthouses designed to capture views across Middle Harbour, Sydney Harbour and the surrounding district.&nbsp;

The project is expected to appeal to downsizers and owner-occupiers seeking house-like proportions, privacy and local convenience. There will be north-facing Middle Harbour views from the second level upward. It is also just a flat 100-metre walk to Bridgepoint Shopping Centre, which will appeal to owner-occupiers and in particular downsizers.

Two-bedroom residences are expected to be priced from $1.99 million when sales launch later this year. 
&nbsp; 
Joe Tack, CEO at Abadeen, said the outcome reflects both the quality of the site and the broader need for well-located housing. 
&nbsp; 
“This is a highly considered site within a highly established local setting, offering elevated views and strong connectivity. The project has been designed to respond to that context, delivering a scale and quality of housing aligned with both the planning framework and evolving market demand.” 
&nbsp; 
“This approval is particularly significant in the context of Mosman, where new housing supply has historically been limited. While it represents the first approval of this scale in Mosman to be achieved in over 50 years, it is importantly located within a well-established residential location, in close proximity to the established commercial amenity of Spit Road and Mosman Village. It reflects strong confidence in Abadeen’s approach to design, delivery and community integration, while contributing to the delivery of much-needed housing in a highly constrained market.”

Abadeen has an established track record across Sydney’s Lower North Shore, with recent completions including KOYO in Crows Nest and ENSO in Neutral Bay.

In Mosman, Abadeen recently completed The Hampden, with Mosman Residences on the corner of Spit Road and Clifford Street scheduled for completion later this year. Construction has also commenced at Burran Residences, comprising three full-floor ultra-premium homes positioned just 50 metres from Balmoral Beach, with residences expected to achieve prices in excess of $20 million. Two further projects are also progressing through planning within the local government area.

Abadeen secures first approval under low and mid-rise housing policy for Heydon Street, Mosman apartment development

Apartment developer <a href="https://www.apartments.com.au/developers/martello">Martello™</a> is one of the latest entrants to the Gold Coast development market, with its debut project set to be one of the most boutique offerings on Chevron Island in recent years.

Martello has unveiled <a href="https://www.apartments.com.au/new-apartments/aere-chevron-island-18-20-mawarra-street-chevron-island-qld-4217">Aere Chevron Island</a>, a collection of 33 large-scale two-, three-, and four-bedroom apartments across an 18-storey building on Mawarra Street.

[smartcode_project:default project_id=143932 project_image_fid=367517]

The developer has placed a strong emphasis on wellness, briefing architecture firm Raunik Design to embed this philosophy into the project. It is a direction <a href="https://www.apartments.com.au/developers/martello">Martello™</a> plans to carry through its future developments along the coast.

<a href="https://www.apartments.com.au/developers/martello">Martello™</a> has positioned Aere as a continuation of its human-centric development approach, with a focus extending beyond amenity to the fundamentals of layout, natural light, and spatial planning. Promax Construction has already been appointed to deliver the project, with construction expected to commence in the coming months as part of the group’s broader expansion into South East Queensland.

Rising above the low-rise fabric of Chevron Island, Aere’s design emphasises generous internal proportions and uninterrupted outlooks, with residences oriented to capture coastal, skyline, and waterway views. Interiors prioritise open-plan living, with large-format glazing and carefully considered transitions between indoor and outdoor spaces.

[smartcode_project:default project_id=143932 project_image_fid=367508]

The upper levels are dedicated to larger-format homes, including four-bedroom residences designed as half-floor offerings. These layouts prioritise separation between living and sleeping zones, along with increased privacy and storage, features more commonly associated with detached housing than traditional apartment product.

Aere’s private resident amenity spaces centre on wellness. A rooftop level will incorporate a heated swimming pool, sauna and spa, while the rest of the wellness spaces throughout the building include a&nbsp;residents’ lounge, dining areas and a gym.

The inclusion of both social and quieter retreat spaces reflects a broader shift in higher-end apartment design on the Gold Coast, where developers are increasingly responding to owner-occupier demand for buildings that support long-term living rather than short-stay use.

[smartcode_project:default project_id=143932 project_image_fid=367814]

Aere is positioned within walking distance of Chevron Island’s village centre along Thomas Drive, as well as the HOTA cultural precinct via the Green Bridge, connecting residents to parklands, galleries, and event spaces.

For <a href="https://www.apartments.com.au/developers/martello">Martello™</a>, Aere represents the first in a series of planned Gold Coast developments, with the group also exploring opportunities in other coastal precincts, including Kirra and Palm Beach.

The move north comes as sustained population growth and infrastructure investment continue to reshape South East Queensland, with developers increasingly targeting boutique, design-led projects in established lifestyle pockets. Aera’s relatively small scale and emphasis on spatial quality position it within this emerging segment of the market.

Martello™ enters Gold Coast market with wellness-led Chevron Island development Aere

Development approval has been granted for Crescent, a boutique waterfront project on one of Palm Beach's most coveted and rarely developed streets.

Launched to market this month, <a href="https://www.apartments.com.au/new-apartments/crescent-palm-beach-34-36-murlong-crescent-palm-beach-qld-4221">Crescent</a> will occupy four combined lots with frontage to both Murlong Crescent and Tallebudgera Drive. The project is among the first new developments to get a green light on the creekside strip, home to only 21 tightly-held properties.

“Murlong Crescent is one of those streets that people discover and never want to leave,” said Andrew Erwin of NPA Projects, who is leading sales and marketing.

“The lifestyle here is genuinely hard to find anywhere else on the Gold Coast.”

Designed by Queensland firm ᴮʸculprit and developed by DCS Property Group, Crescent offers two and three-bedroom residences across four levels, ranging from 119 to 283 sqm and priced from $2.5 million. Builder SNBX Constructions has been appointed, with completion expected in mid to late 2028.

[smartcode_project:default project_id=151399 project_image_fid=366218]

Residences face north to Tallebudgera Creek, with views that extend to Burleigh Headland. Upper levels also capture canal and hinterland views to the west.

“The creek is tidal, so it changes constantly. The colour, the light, the mood of it,” Erwin said.

“That view over the creek to Burleigh Headland is only possibly from this location.”

[smartcode_project:default project_id=151399 project_image_fid=366213]

Crescent devotes two levels, spanning more than 1,100 sqm, to resident amenity.&nbsp; On Level 1, a gym, steam room, infrared and traditional saunas, hot spa, cold plunge, and ice bath make up the private wellness retreat. Entertaining and recreation converge on the rooftop with a resort- style pool and sundeck, alfresco BBQ and dining areas, pizza oven, yoga lawn, fire pit, as well as a herb and zen garden. Residents can also jog or walk along a dedicated loop with views over Tallebudgera Creek.

“The amenity here is genuinely out of proportion to the size of the building,” Erwin said.

“Every resident, regardless of which apartment they choose, gets access to the kind of amenity normally associated with luxury resorts.”

[smartcode_project:default project_id=151399 project_image_fid=366257]

Residences feature natural stone and timber finishes throughout, brushed brass tapware, and New Zealand wool carpet to bedrooms. Two basement levels provide secure parking, with provision for electric vehicle charging.

Beyond calm water swimming, paddling and boating, residents follow the foreshore path to Tallebudgera Beach, local cafes, and Tallebudgera Surf Club, while across the bridge is Burleigh Heads National Park, Burleigh Beach and the vibrant James Street dining and retail hub.

Palm Beach has been among the Gold Coast’s strongest performing suburbs over the past five years, with median house prices having risen by more than 91 per cent and unit values more than doubling in the same period.

Crescent Palm Beach approved as sales launch

The Albanese and ACT Governments have struck a deal to unlock nearly 5,000 new homes across Canberra, with more than 1,700 earmarked exclusively for first home buyers.

The agreement marks the second formal partnership under the Federal Government’s election commitment to deliver up to 100,000 homes for first home buyers nationally, working alongside state and territory governments and industry.

At the centre of the deal is a $250 million funding injection from the Albanese Government, targeting enabling infrastructure to bring forward new housing supply across a number of key precincts in the ACT.

That includes funding to unlock 75 homes in the Kingston precinct, support new development in Weston Creek, and deliver estate works across the territory that will facilitate more than 500 homes by 2034. Additional investment will go towards relocating powerlines, water infrastructure in Molonglo Valley, and further expansion of the Ginninderry regeneration precinct.

Housing Minister Clare O’Neil said the agreement was about making it easier for first home buyers to enter the market, particularly in a housing environment that continues to challenge affordability.

“We’re determined to make it easier for young people and first home buyers to achieve the dream of owning a home,” O’Neil said.

“We know the housing market is tough, and we want Australians to know that Labor has got your back.”

The announcement builds on more than $800 million already committed to housing in the ACT since 2022, according to Finance Minister and ACT Senator Katy Gallagher, who said the latest funding would help ensure national housing programs are translating into real supply on the ground.

“We’re working closely with the ACT Government to unlock land and invest in the infrastructure needed to get these homes built sooner,” she said.

For the ACT Government, the agreement aligns with its broader target of delivering 30,000 new homes by 2030, with Chief Minister Andrew Barr pointing to the role of coordinated planning and infrastructure investment in accelerating delivery.

“Now, thanks to our agreement with the Albanese Government, this work is about to reach a new level,” Barr said.

The deal sits within the Federal Government’s broader $45 billion housing agenda, which includes initiatives such as the Housing Australia Future Fund, the Help to Buy shared equity scheme, and incentives aimed at increasing construction capacity and reducing barriers to development.

Native Birds

GUSET OBSERVATION
Glossy Black-Cockatoos used to be common on South Australia’s Kangaroo Island until possums started eating their eggs and chicks. After volunteers helped protect nest hollows and erect safe nest boxes, the population more than doubled.
But how do you measure such success? How do you compare cockatoo nest protection with any other investment in conservation?
Unfortunately, we have few ways to compare and track the different efforts many people may be making to help conserve our natural treasures.
That’s why a group of us from a dozen Australian universities along with scientists and private researchers around the world have created <a href="https://onlinelibrary.wiley.com/doi/10.1111/cobi.13220">metrics of progress</a> for both our understanding of how to manage threats of different intensity, and how well that management has been implemented. We also provide guidance on what still needs doing before a threat no longer needs active management.
For the first time, we looked at every threatened bird in Australia to see how well – or not – they are managed. Hopefully, we can use this to avoid compounding our disastrous <a href="https://www.theguardian.com/environment/2018/feb/13/a-national-disgrace-australias-extinction-crisis-is-unfolding-in-plain-sight">recent track record</a> of extinctions in Australia.
The state of Australian birds
What we did differently was collect the same data across different species, which meant we could compare conservation efforts across all bids.
<a href="https://images.theconversation.com/files/246799/original/file-20181122-182062-zfg4ry.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/246799/original/file-20181122-182062-zfg4ry.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt=""></a>
The mallee emu-wren is unique to Australia and endangered due to habitat loss. <a class="source" href="https://www.flickr.com/photos/128578170@N06/24288853338/in/photolist-D1jHTq-4b9JJc" target="_blank">Nik Borrow/Flickr</a>
When we applied these metrics to Australia’s 238 threatened bird species, the results were both encouraging and daunting. The good news is that we understand how to reduce the impact of about 52% of the threats – although of course that means we know little about how to deal with the other 48%.
But the situation is decidedly worse when we consider how effectively we are putting that research into practice. Only 43% of threats are being managed in any way at all – and just a third of the worst threats – and we are achieving good outcomes for just 20%.
But at least we now know where we are. We can celebrate what we have accomplished, appreciate how much needs doing, and direct our efforts where they will have the greatest benefit.
The threats to our birds
Introduced mammals, particularly <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320717302719" target="_blank">cats</a>, have been (and continue to be) a significant threat to Australian birds. Although we have successfully eradicated feral animals on many islands, saving many species, they remain a grave threat on the mainland.
The effect of climate change is becoming the top priority threat for the future. About half of all threatened birds are likely to be affected by increases in drought, fire, heat or sea level. Given the policy prevarication at a global level, targeted research is essential if birds are to be helped to cope.
By looking at multiple species, we can also identify what helps successful conservation. <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/emr.12335" target="_blank">Monitoring</a>, for instance, has a big impact on threat alleviation – better monitored species receive more attention.
There is also – unsurprisingly – a strong connection between knowledge of how to manage a threat and successful application of that knowledge. Often policy people want instant action, but our work suggests that action before knowledge will squander money.
Where to from here?
So what can we use this analysis for? One use is helping species <a href="http://www.nespthreatenedspecies.edu.au/news/no-surprises-no-regrets-identifying-australias-most-imperilled-animal-species" target="_blank">close to extinction</a>.
Using the same approach for multiple species groups, it is apparent that, while birds and mammals are in a parlous state, the most threatened fish are far worse off. We can also identify some clear priorities for action.
Finally, we must acknowledge this work emerged not from a government research grant, but from a non-government organisation (NGO). BirdLife Australia needed an overview of the country’s performance with threatened birds and was able to draw on the volunteered skills of biologists and mathematicians from around the country, and then the world.
Indeed, one of the future projects will be using the new assessment tool to see just how much of the conservation action around the country is being driven by volunteers, from the many people who contributed their knowledge and skills to this paper through to those keeping glossy black-cockatoo chicks safe on Kangaroo Island.<img src="https://counter.theconversation.com/content/107432/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

For the first time we’ve looked at every threatened bird in Australia side-by-side

<html><body>
GUEST OBSERVER
The fourth <a href="https://aussiebirdcount.org.au/" target="_blank">Aussie Backyard Bird Count</a> has just ended, with nearly 2 million birds from 635 species submitted to the BirdLife Australia app. The count, which is in its fourth year, has created a national database of birds found in our backyards.
We don’t know yet exactly how many people participated this year, but more than 60,000 people submitted checklists in 2016. Participants span the whole country, though participation is highest in our urban areas. By surveying our backyards (rather than “good” bird spots), these citizen scientists provide ecologists – like me – with information from urban areas we would not otherwise sample.
This includes data on a range of common bird species that are not frequently analysed because these species are believed to be secure. One of the most surprising results is a decline in the frequency of occurrence of the laughing kookaburra across southeast Australia.
Counting birds
Everyone has a bird story – and fortunately for ecologists, everyone is willing to share them. With 85% of Australia’s population living in cities and towns, birds are an important connection to our natural environment.
<a href="https://images.theconversation.com/files/192541/original/file-20171031-18711-13owlfd.PNG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/192541/original/file-20171031-18711-13owlfd.PNG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt=""></a>

But birds are also <a href="https://www.bioone.org/doi/abs/10.2326/osj.9.3?journalCode=jorn" target="_blank">good environmental indices</a>. They’re generally easy to measure, they respond quickly to environmental change and we know a reasonable amount about the ecology of most species.
Between 1998 and 2014, BirdLife Australia volunteers collected a significant amount of data. This was used to develop a terrestrial bird index in 2015 – a bird “Dow Jones” to track our biodiversity. It was here that the decline in kookaburras was first identified.
The data were drawn from BirdLife Australia’s ongoing atlas project, now called <a href="https://birdata.birdlife.org.au/" target="_blank">Birdata</a>. However, there are biases in this data set, as people obviously like to go birdwatching where they will see more birds. This may inflate the frequency of encountering some species and decrease the chances of encountering others – particularly rare and cryptic species.
For the last four years, we’ve asked volunteers to add to this data by counting birds around their home for a week in October, when many birds are highly active and visible. These counts complement the data already available in Birdata by allowing access to backyards across Australia, which are generally poorly represented in the larger data set.
While there are still limitations in the Backyard Bird Count data, such as the risk of mis-identification, for common species like the laughing kookaburra we can generally be confident that the identification is correct. Even if the same bird is counted multiple times, our models report only a species’ presence or absence, so inflated numbers don’t affect the trend.
Are kookaburras really declining?
The below figures show modelled trends for the kookaburra across metropolitan Melbourne and Sydney. These figures are derived from the volunteer-collected Birdata, much of which comes from green spaces and remnant vegetation in these landscapes.
I wondered whether these declines are true changes in the populations, or reflect a change in the way kookaburras are using the landscape, possibly moving into the matrix of urban backyards that just don’t get surveyed. Looking solely at the backyard count data, I found similar trends in the reporting rates of kookaburras as those in the models, supporting that this decline is at the population level. What started out in 2014 as a way of engaging the broader community with their birds is now collecting useful ecological data.
Further exploration of the ABBC data across other capital cities found some interesting things. In both Perth and Hobart, where the kookaburra is considered an introduced species, the birds are recorded more frequently than in Melbourne and across the ACT. In Perth, increases in 2016 compared to previous years suggest an increase in the species there.
<a href="https://images.theconversation.com/files/192539/original/file-20171031-18700-ecicwi.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/192539/original/file-20171031-18700-ecicwi.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Modelled trends for Kookaburras from 1998-2014. Source: Unpublished models/K. Herman/BirdLife Australia, Author provided
The figure on the left is for Melbourne, and on the right is for Sydney. The reporting rate shows the percentage of surveys where kookaburras were recorded as present. The thick black line is the modelled trend (with confidence intervals in dashed line), the pink line shows the statistically significant linear trend, the thin black line shows the monthly calculated reporting rate, and the green spots show acceleration (or a favourable change) in the trend. Note that due to modelling method, the ends of figures tend to blow out as there is no data from which to predict trend.
While three years does not make a trend, Aussie Backyard Bird Count data from heavily urbanised areas suggest we are seeing a decline in this iconic species in the eastern capitals. Likely reasons for this are the loss of nesting hollows and possibly reductions in the availability of prey as we increasingly modify our urban landscapes. We don’t really know as this is not an area that has been researched.
We need citizen scientists
Collecting enough data (especially from the backyards of towns and cities) to detect these kinds of changes can be an overwhelming task. This is where citizen science programs like the Aussie Backyard Bird Count can help.
As well as helping ecologists track large-scale biodiversity trends, it also gives people the chance to connect with their natural environment and gain a greater appreciation of our unique fauna.
As with all citizen science projects, there are limitations in the data being collected. However, the Backyard Bird app has been designed to make counting as simple and standardised as possible, providing confidence in the tally of common and “iconic” species, and filling in the gaps found in other data sets.
The good old kookaburra is neither rare or cryptic. If anything, if people are seeking out “good” bird habitat to survey we would expect that kookaburras would be one of those species subject to inflated reporting. But this is not what we encountered.
<img src="https://counter.theconversation.com/content/86469/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">If we are starting to see declines in species that we have traditionally considered secure, what does this mean for those that are already at risk? Once all the data from the Aussie Backyard Bird Count have been collated and vetted we will continue to explore the developing trends in Australia’s urban birds. Increasing engagement and awareness in our communities can help ensure our backyard birds are still around to count next year.

Life in the city can be stressful – for birds just as much as people. For humans, cities are expressly designed to put roofs over heads and food within easy reach, but the opposite can be true for many urban birds. They can find food and shelter harder to come by in the concrete jungle – with some notable exceptions.
For any species in any habitat, survival is about problem-solving and adapting to the environment. So what street smarts do city birds need? And why do some species, such as lorikeets, crows and ravens, seem to dominate our urban landscapes?
In general, urban birds must be bolder than those that remain in natural habitats, as can be seen by the boldness (or “habituation”) with which some species will forage for food with people nearby. But they also need to be able to avoid or retreat from unfamiliar objects or situations if they seem dangerous.
City birds also need to withstand exposure to a wide range of pathogens. A study of birds in Barbados found that urban birds have enhanced immune systems relative to their country counterparts.
While we have changed the environment in which some birds live, reducing resources in terms of food and shelter and increasing the number of pathogens that may impact their health, some birds have largely benefited from the new way of life.
<h2>Winners and losers</h2>
Within the urban ecosystem, there are winners and losers in the bird world. The suburban landscape, for example, now provides more nectar from flowers than native vegetation due to the gardens that people have established. This is a big help to nectar-feeding parrots such as Rainbow Lorikeets.
A recent study in Sydney found that the lorikeets benefit from the increased abundance of flowers in urban areas, and their numbers were higher in the leafy suburbs than in bushland.
But if urban areas are such a rich source of nectar, why are some nectar-feeding species declining?
The Regent Honeyeater feeds mainly on nectar and other plant sugars. It has been seen in orchards and urban gardens, but is listed as critically endangered by the federal government.
This is partly because widespread clearance of woodland habitat has led to the increase of the aggressive Noisy Miner and Red Wattlebird. These species find it easy to “bully” other birds in open habitats. Noisy Miners have been observed pulling apart Regent Honeyeaters' nests as they were being built.
Regent Honeyeaters, in contrast, are less adaptable to changed landscapes, because they are migratory and rely on detailed knowledge of existing food sources. If these resources are changed or removed, they may not have enough interconnected patches of habitat to move safely towards new resources – potentially leaving them vulnerable to cats, foxes and aggression from other birds.
Habitat loss can threaten some bird species or even leave them at risk of dying out if they do not locate alternative resources. The ability to find new food sources therefore becomes a valuable survival skill.
<h2>What’s more useful: flexibility or intelligence?</h2>
For some bird species, flexibility in finding food is crucial in making a successful switch to urban environments. One example is the Grey-crowned Babbler, which is endangered in Victoria, but my colleagues and I have documented it living in a suburban area in Dubbo, New South Wales.
This species usually nests in coniferous woodland and forages in the leaf litter beneath the trees. But in Dubbo, we saw these birds feeding on lawns, in playgrounds and even in leaf litter along a train track at the back of urban housing, sometimes visiting backyards along the way. This suggests that these birds can survive the loss of their woodland habitat by being sufficiently adaptable to life in the suburbs – as long as they can continue to find enough food, disperse between nearby groups and have access to native nesting trees.
For other species, such as crows and ravens, intelligence seems to be the key. These species can survive anywhere in the urban sprawl, including places where trees are scarce but rubbish bins are everywhere. Crows and ravens can literally pull food out of a bin and eat it – clearly a learned behaviour that has resulted from problem-solving.
These birds are highly opportunistic and social, allowing them to learn new ways of adapting to the almost complete removal of their natural environment.
<h2>Survive and thrive</h2>
What we can deduce from these examples is that some birds, like Rainbow Lorikeets and Grey-crowned Babblers, can adapt successfully to the urban sprawl as long as some characteristics of their habitat still remain. Other species, such as crows, have gone a step further and worked out how to survive purely on urban resources – effectively making a living in an environment that is completely unnatural to them.
This suggests that the more we urbanise an area without natural aspects, the less bird diversity we will have – and the more our urban areas will come to be dominated by those few species that are hardy, clever or adaptable enough to thrive.
Luckily, some councils in Australia and cities throughout the world are bringing the natural aspects of the forest back into the concrete jungle, so that a wider range of birds might survive here. More research is needed to work out exactly what each species will need, but planting more native plants is always a good start.

Blocks and flocks: why are some bird species so successful in cities?

<html><body>
GEUST OBSERVER
Some Australian birds are pushing out other species, and even damaging trees. Noisy and bell miners are two of Australia’s most aggressive bird species. Found throughout eastern Australia, in recent years their numbers have increased at the expense of our smaller birds.
Both myna species are spreading to new areas, largely due to human destruction of habitat. Noisy miners are able to invade areas where habitat has been modified, particularly gardens.
Bell miners, meanwhile, can invade areas that have invasions of weeds in the understorey such as blackberry and lantana that they use for nesting.
The good news is we can help stop the spread of these birds, by putting native plants in our gardens.
<h2>Good birds gone bad</h2>
Both species of these miners (genus Manorina) have been found to reduce bird diversity through their aggressive behaviour, and have been associated with eucalypt dieback.
Human disturbance has been linked to increasing numbers of noisy miners. One study in the box-ironbark forests of southeast Australia, found that noisy miners an move into areas of smaller fragments and unhealthy trees.
They then chase away other birds, reducing the number of species and potentially having knock-on effects on ecosystems. The problem is so serious that noisy miners are listed as a national threatening process.
More research is needed to find out why bell miners are becoming more common. But our research has found that bell miners show similar behaviour to noisy miners. They have a distinctive call that travels for tens of metres through the forest.
Bell miners cause Bell Miner Associated Dieback in trees. It is thought that their feeding and breeding behaviours lead to the death of eucalypts on the east coast of Australia. They also take over habitat that would be used by other birds.
<h2>Are the birds to blame?</h2>
Where miners are normally found in lower numbers, disturbances by people can tip the balance in their favour. This includes increasing noise levels, removing corridors of connecting native vegetation, creating gardens with exotic plants, building cities, houses, parks, logging and introducing invasive species that create thick understories.
These disturbances increase the habitat available for these two species, allowing them to increase in number and drive out the smaller birds that compete for their food sources.
Noisy miners particularly favour open areas that don’t have thickets of shrubs of smaller trees underneath the canopy. Conversely, bell miners prefer thick understoreys, particularly those create by introduced weeds such as lantana.
So if we are causing these birds to increase in number, how can we reduce their numbers and re-create the original habitat where all species could co-exist?
<h2>Build a bird-friendly garden</h2>
You need to create a multi-layered habitat of ground covers, small and medium shrubs, and trees that provide food and shelter locations all year for a variety of species.
These plant species need to have diverse structures, and should be close together to form dense, protective thickets, including climbers within medium-to-tall shrubs and trees, nectar-bearing and seed-bearing plants. Mulch can also encourage insect life for insectivorous birds.
Plants should also be local species that grow naturally in the area and are suited to the climate. Native birds that live in the area will then visit your garden as another food source in their territory.
Reducing weeds in your garden and neighbouring bushland (many weeds are derived from garden plants) can help native species. General natives can also be planted if you can’t find local natives in your local nursery.
Even in gardens where noisy miners dominate, smaller birds can survive in a dense understorey.
Meanwhile, a thin midstorey with fewer leaves may help to reduce bell miner abundance, as suggested by our recent study near Kyogle, New South Wales.
You should also consider the timing of flower and fruit production, to ensure that there is always food available for birds. You should also remove fruiting plants such as cotoneaster and blackberry that attract predators such as currawongs, to help reduce predation on smaller bird species.
Using chemical-free weed and pest control and mulching garden waste can also increase the food available for birds.
Lawns can also be replaced with native grasses that produce seed to attract finches and other seed-eaters such as crimson rosellas. Birds also need fresh water, which you can provide with a pond or bird bath. This should be placed within vegetation to ensure birds feel safe from predators.
<h2>Why are native gardens important?</h2>
Local biodiversity can be maintained by native gardens, ensuring long-term ecological sustainability. Small birds and other wildlife benefit from planting native species.
Many species are negatively affected by the current structure of gardens such as lawns, few scattered trees and the placement of concrete and houses without any access to nesting habitat.
Gardening in Australia needs to be changed to favour more native species and provide structure on a landscape scale that includes a variety of gardens.
