If you sit in an Australian park or garden for long enough, chances are you might catch a flash of brilliant feathers out of the corner of your eye: the superb fairywren.<\/p>\n

With its bright blue and soft brown plumage, it was voted Australia\u2019s \u201cbird of the year\u201d in 2021, \u201cnarrowly defeating the tawny frogmouth in a nail-biting finish\u201d in a\u00a0poll<\/a>\u00a0by Guardian Australia and BirdLife Australia.<\/p>\n

Yet, despite its seeming abundance in gardens and backyards, this iconic bird is showing worrying signs of decline.<\/p>\n

Superb fairywrens (Malurus cyaneus<\/em>) are found in any habitat with dense shrubbery along the east coast of Australia, parts of South Australia and Tasmania.<\/p>\n

Despite being categorized as\u00a0least concern\u00a0on the IUCN Red List, a long-term study of superb fairywrens conducted in the\u00a0Australian National Botanic Gardens\u00a0in Canberra determined that they\u2019re disappearing, with climate change impacting their survival.<\/p>\n

Scientists have been monitoring these superb fairywrens since 1988, and\u00a0research\u00a0led by the Australian National University\u2019s\u00a0Cockburn Group\u00a0found that this population has rapidly declined. In a recently published article in\u00a0Nature Communications<\/em>, the researchers write that this \u201ccommon species \u2026 is in imminent danger, with virtually no time or way to prevent it.\u201d<\/p>\n

\u201cWe have seen some dramatic changes in the fairywren population in the Australian National Botanic Gardens,\u201d said Damien Farine, a researcher from the Australian National University, who took over monitoring of the population in 2024.<\/p>\n

During the Australian winter of 2025,\u00a0more than 50% of adult birds perished\u00a0and nearly all juveniles \u2014 95% \u2014 in the gardens died. Farine said he believes this was likely caused by a combination of warm autumn temperatures followed by a sudden cold winter in Canberra, a weather phenomenon sometimes called weather whiplash.<\/p>\n

Farine assessed the rate of the superb fairywren\u2019s historical decline using data gathered in the gardens from the period of 1993 until 2022. This informed projections of the species\u2019 future under various climate scenarios, from no further climate change to low, intermediate and very high emissions.<\/p>\n

He found that population extinction was likely within the next 30-40 years under the intermediate and very high emissions scenarios. However, the actual decline in the two years following the study was even more concerning, outstripping modeling.<\/p>\n

\u201cWithin two years \u2026 the declines are worse than every single prediction from even the worst-case scenario model,\u201d Farine said.<\/p>\n

The findings highlighted the \u201ccatastrophic cumulative effect\u201d that multiple small impacts from climate change can have on wildlife.<\/p>\n

For the fairywren, this includes poor breeding, with few chicks successfully fledged in abnormally dry springs where little rainfall contributes to female bird deaths and low migration between populations.<\/p>\n

A worrying trend<\/h2>\n

This is indicative of a larger, worrying worldwide trend: native birds, insects and biodiversity are\u00a0slipping\u00a0away.<\/p>\n

\u201cThe superb fairywren is just one example of a large suite of small and medium woodland birds that are declining at roughly similar rates,\u201d Farine said.<\/p>\n

It\u2019s a global phenomenon. These declines aren\u2019t limited to Australia, he added, but are being \u201creported almost everywhere \u2014 even in undisturbed habitats \u2026 and point to some fundamental issues with the functioning of our ecosystems.\u201d<\/p>\n

One reason is food, he said. Climate change, as well as habitat loss, and use of pesticides is\u00a0making it harder\u00a0for birds that survive on a diet of insects, like the superb fairywren, to find enough to eat. Australia experiences from one to three invertebrate extinctions every week, according to a study published in\u00a0Cambridge University Press<\/em>.<\/p>\n

\u201cClimate change impacts multiple aspects of insect life, such as survival rates, feeding patterns, fecundity and movement patterns,\u201d said Christina Zdenek, who serves as urban birds program coordinator at BirdLife Australia.<\/p>\n

Fewer insects mean fewer fairywrens, she said.<\/p>\n

The relationship between less food and declines of woodland birds remains understudied. There have been\u00a0calls\u00a0in the scientific community for greater collaboration between ornithologists and entomologists in Australia to fully understand the link.<\/p>\n

What can we do?<\/h2>\n

Amid increasing extreme weather and changing climate, Anne Peters, deputy head of the School of Biological Sciences at Monash University, said Australians impassioned by the plight of the fairywren can take action.<\/p>\n

One way to support woodland birds and superb fairywrens is to cultivate insect-friendly urban gardens that include an abundance of native plants and shrubs.<\/p>\n

\u201cIf we, as a society, take actions that would improve insect numbers \u2026 it \u00a0would probably directly and indirectly benefit small songbirds,\u201d she said.<\/p>\n

\u201cI think every individual could, even if you don\u2019t have a garden, use your balcony or plant something in your nature strip.<\/p>\n

\u201cWe need connected green space, high-quality native habitats [and] gardens that are bird and insect friendly \u2026 a good understory, midstory, overstory, a little bit of tangled, messy, dense vegetation.\u201d<\/p>\n

Michael Gisick, editor of the Canberra Organic Growers Society\u2019s magazine and local gardener, is passionate about gardening with insects and birds in mind.<\/p>\n

\u201cCommunity gardens and other urban and suburban gardens certainly can play a role in supporting biodiversity, even when they are oriented primarily toward growing food for people,\u201d he said.<\/p>\n

\u201cSetting aside areas of the garden for wildlife and dense shrubbery provides especially important habitat for small birds [as well as] providing sources of water, especially when the weather is hot,\u201d he said.<\/p>\n

However, BirdLife Australia\u2019s Zdenek noted that insects are only part of the conservation picture.<\/p>\n

\u201cBoosting insect numbers may have a positive impact on fairywrens, but food is just one of the key requirements for fairywren survival,\u201d she said.<\/p>\n

\u201cThey also need structure and complexity of vegetation in their environment to protect them while they hunt \u2026 Without structures like shrubs that occupy the 1 to 3-meter [3.2 to 9.8-foot] strata in the environment, they\u2019re super vulnerable to aggressive \u2018mobbing\u2019 behavior by noisy miners \u2014 birds that are already extremely favored by our love of lawns with scattered gum trees.\u201d<\/p>\n

Noisy miners (Manorina melanocephala<\/em>) are an aggressive and territorial Australian native that relentlessly swoop and attack other birds. Their population has boomed alongside urban development, as they adapt well to altered landscapes. Their mobbing behavior can harm \u2014 or kill \u2014 superb fairywrens and other native bird species.<\/p>\n

Superb fairywrens hold a special place in the hearts of Australians. Communities can take charge to shape a better world for their beloved bird, Zdenek noted.<\/p>\n

\u201cThe science is clear: the biggest threat to Australian species is habitat destruction, so utilizing already-cleared land more wisely and preventing more land-clearing is the number one recommendation to conserve fairywren populations,\u201d she said.<\/p>\n

\u201cBeyond protection, there\u2019s restoration. People can pressure local governments to plant a diversity of locally native shrubs and groundcovers to replace lawn wherever possible.\u201d<\/p>\n

Citizen science and community action<\/h2>\n

But while boosting insect numbers through gardening may help, more research into the exact drivers of this decline and the correlation between insect and bird health in Australia is needed.<\/p>\n

Australian National University\u2019s Farine said they don\u2019t know enough about the causes. \u201cThis is because our data are largely limited to systematic counts. This can tell us about the declines, but not about why they are happening. We can\u2019t go back in the past to collect these data, so we\u2019re limited to a handful of studies that can give us the historical perspective against which we can understand contemporary changes.\u201d<\/p>\n

Experts say that identifying the driving forces behind the rapid global declines of woodland birds is critical to conservation efforts. More collaboration between ornithologists, and entomologists could be key to this work.<\/p>\n

While studies such as the one conducted at Canberra\u2019s National Botanic Gardens paint a bleak picture, everyday citizens and communities are already taking meaningful action by ensuring their gardens and outdoor spaces offer sanctuary for birds and insects alike, particularly Australia\u2019s beloved superb fairywren.<\/p>\n
