Noisy Scrubbird

Atrichornis clamosus

The Noisy Scrubbird, Atrichornis clamosus, presents a dark brown back, rust-coloured wings, and a speckled chestnut breast. Its bill ranges from grey-brown to pink, while its legs and feet can be brown or silver. These birds measure between 19 to 23 centimeters in length and weigh between 25 to 58 grams. Males are marked by a distinctive black triangle on their throat.

Identification Tips

To identify the Noisy Scrubbird, look for the male's black throat triangle. Their size is relatively small, and their colouring is predominantly dark with rust and chestnut hues. The bird's dense habitat can make visual identification challenging, so awareness of their distinctive calls is beneficial.


The Noisy Scrubbird thrives in dense ground-cover wetlands within subtropical to temperate rainforests, typically at elevations greater than 600 meters. They require closed forests with a height of 5 to 15 meters and a preference for areas recovering from environmental disturbances such as fires or logging.


Endemic to south-western Australia, particularly east of Albany, the Noisy Scrubbird's range is limited to approximately 45 square kilometers, including populations at Two Peoples Bay and Bald Island.


These birds are elusive and prefer extremely dense understory. They are known to colonize areas recovering from damage within as little as 2 years, but are not found in regions that haven't experienced disturbance in the past 50 years.


Noisy Scrubbirds reach sexual maturity around 5 years of age. They lay one egg at a time, with a total clutch size of two. Nests are circular and built from sticks, leaves, and plant matter in low vegetation. Males do not contribute to nest-building but may defend the territory. Eggs are incubated for about 36 days, and chicks fledge 4 to 6 weeks post-hatching.

Diet and Feeding

Their diet consists mainly of small invertebrates, such as ants and beetles, which they forage for in the leaf litter of their dense habitats.

Conservation Status

The Noisy Scrubbird is classified as Endangered on the IUCN Red List. Despite conservation efforts, populations are declining due to threats like forest fires, predation by introduced species, habitat degradation, and disease. Conservation strategies include predation control, habitat monitoring, and careful management of forest fires to prevent further population decline.

Birding and wellbeing app
Birda is an excellent platform to share your love of Birding and is a great tool of encouragement for a Birding Beginner like me. Birda has a very kind and supportive community of Birding enthusiasts. For me BIRDA is not only a BIRDING but also a WELLBEING App.

A great app
Enjoying it immensely and finding it useful too. Recording the different birds and counting them is showing me how the present climate is affecting them all. I've trebled the numbers by planting native hedging. A great app.
Really great app
It’s easy to use and it’s fun to log the birds you notice on a walk or just in your garden. There’s a option to record the birds you see in a session which is really nice. Good excuse to stop for a while and just watch birds. I am also enjoying the information part where you can find out fact about birds from all over the world.

Clean and easy to use
Really enjoying this app, it's clean and easy to use. I love the ease of being able to add those one-off birds without starting a whole checklist. I also like the social aspect, like the parts of my Facebook I like, without the ads and junk, just birds. Can't wait to see it become more populated.
Wonderful App
Birda is my go to app for keeping records of my bird sightings and sessions. It has fantastic information which is great at aiding identification. With all the updates that are coming in the new year, this app is something special.

Awesome Birding Community
I absolutely love the community aspect of this app. The app is so user friendly and has fun interactive challenges to get you out birding. I’ve tried others but since I’ve started using Birda I’ve not gone back!
Great app for learning Birds
I’ve been using the app for a couple of months and love it....Someone said it’s like a real life Pokémon Go for birds. They’re not far off! It’s something that the family can do that gets you out and about. Well worth downloading no matter your age.
