Have Bird Questions? Ask a Bird Specialist.
Hi this is Dr. Hill. There is a great video called Captive Foraging that you should watch. I will do a search of avian veterinarians for you in your area and be right back.
Take a look at this site and see if anyone is close to you while I get some more information for you. http://www.myhouseofwings.net/Pennsylvania_Avian_Veterinarians.html
Here is a site with the captive foraging DVD. It is great. Take a look and get back to me with your additional questions. https://www.avianstudios.com/products/captive-foraging-dvd/
Almost any avian veterinarian has experience with a feather plucking cockatoo, unfortunately. Cockatoos and African Greys are the two most common birds we see feather destructive behavior in. Very frustrating problem but the Captive Foraging DVD will help get you started. I have a feather destructive Grey who was a rescue.
