New Homes for Cockatoos

The alpine forests of Australia’s southeast are home to an iconic pint-sized gray parrot with a bright red mohawk, and a call that’s been described as a “flying creaky gate”. The Gang-gang Cockatoo has seen significant habitat loss in recent years, especially after the 2020 wildfires. It’s now listed as an endangered species. A new national working group is coordinating recovery efforts. Researchers and community scientists are trialing an innovation on the Gang-gang population called the “Cockatube” — a PVC tube designed to host a cockatoo nest.

The Gang-gang Cockatoo has seen significant habitat loss in recent years, especially after the 2020 wildfires. It’s now listed as an endangered species. A new national working group is coordinating recovery efforts. Researchers and community scientists are trialing an innovation on the Gang-gang population called the “Cockatube”.

These cockatoos nest in the hollows of old-growth eucalyptus, lining the holes with bark they strip from surrounding trees. And these large hollows are harder to find after the wildfires. While the Gang-gang would just tear apart a typical wooden nest box, artificial tubes made of beak-resistant PVC might just do the trick.

These “Cockatubes” are the ideal size for a Gang-gang nest and feature drainage holes, a temperature logging device for researchers to check conditions, and a chewing stick for nest material. Volunteers will spend the next five years monitoring the nests, with hopes of jump-starting the Gang-gang population.
