Cockatoo Wingtag

Research is currently under way that involves wing-tagging Sulphur-crested Cockatoos (Cacatua galerita) within the Sydney region, Australia. Wingtags allow all of us to identify individual birds and contribute to the research aiming to learn about the Cockies' behaviour: site-loyalty, population size and foraging, roosting and breeding habitat preferences.

Assist this research by reporting your sightings of wing-tagged birds via the wingtags app on Google Play and App Store, or

Why are you tagging Cockatoos?
We are tagging and tracking Cockatoos to find out how they are adapting to living in the city. Read more about the project above.

What are the birds’ names?
All of the study birds (and their names) can be seen here.

How are the tags attached to the birds?
The wingtags are permanently attached through the birds’ patagium, a section of flexible skin that expands and contracts with the opening and closing of the wing. It’s similar to the loose bit of skin on the inside of your elbow. This method of marking birds with plastic cattle tags as wingtags was first used in the 1970’s on vultures.

How long will the tags remain attached?
Wingtags is a long term project. The tags will remain on the birds until they fall off or the tagged bird removes them. Collecting long-term data is necessary as the Cockies population is subject to natural variations and long term changes that can only be measured by tracking the Cockatoos for years.

Does tagging hurt the birds?
The process is similar to a human getting a skin piercing. The tagging process is quick, and we aim to minimise the distress of the birds. After tagging the birds are closely monitored and we release them within half an hour of being caught. The Cockies tend to initially inspect the tag, but quickly adjust to flying and preening as normal. They are capable of chewing through the tags and removing them.

Have the birds suffered any injuries or adverse effects from the tags?
No, to the best of our knowledge. We know that all of the wing-tagged birds have been resighted, and the majority are regularly resighted. We have received reports of a couple of birds with minor injuries, but they have all subsequently been observed and are in good health.

I’ve seen a sick Cockatoo that is losing its feathers and/or has a deformed beak.
The Cockie probably has Beak and Feather Disease (Psittacine Circoviral Disease). It’s a naturally occurring virus that, unfortunately, is often fatal. There is no widely-available vaccine.

I've found a bird with an injury. Should I take it to a vet?
Both the tagged and untagged birds are wild animals and injuries and illnesses naturally occur. Small injuries that look like they will heal probably will heal. If you see an injured bird that clearly has its welfare compromised or is obviously in distress, you should call the appropriate wildlife rescue group for your area (e.g. in Sydney WIRES or SMWS). We do not recommend you try to catch the bird yourself. Cockatoos have a very powerful beak and being bitten can cause a serious injury.

I have some vetinary questions?
We are ecologists not vets and we cannot offer veterinary advice. Please contact your local vet for any veterinary matters.

Can I feed the birds?
We discourage people from feeding wild animals, although we acknowledge that lots of people feed wild animals—including the wing-tagged Cockies. If you are feeding wild animals, be aware that many foods are not appropriate for them, including some pet food. Where possible, provide ‘natural’ foods, or plant them in your garden.
