My Cockatoos are acting very grumpy and snippy

by Tammie Antonsen

I have two Cockatoos, a female and a male. They both have their own cages. As of late they have been, for lack of a better word, mean. I can reach into their cages and pet them, but if I hold them, separately, they bite and become quite aggressive. My male is 17 years old and my female is 15 years old. I was curious as to whether it was their mating season and that was why they were acting that way or if it is something that I am doing wrong. Can you tell me when their breeding season begins and ends? I live in Denver, Colorado if that helps anything. I am worried about them because they really have never acted this way, especially towards me. Please help me.

Thank You,
Tammie Antonsen

Cockatoos grumpy
by: The Avian Vet

In captivity, they do not have a true ?season?, and reproductive behaviors can occur any time of the year. If this has never happened before and they are this age, then I do not think this is a seasonal reproductive problem. There are many other causes for this behavior.

If these are Umbrella cockatoos, I would not be surprised because this is a common behavior in this species. Sudden changes in behavior can mean your birds are sick and do not feel well, or it could be something else.

Tammie, it is the middle of the winter and not any kind of breeding season for any species of bird or animal in the US.

Your birds may be sick, so I suggest you make an appointment with an Avian Vet in your area and take both of them in for an exam.

Sudden changes in behavior are the first signs of illness in birds, so please do not ignore these signs.

Thanks for writing,
