Wild Animals/Bald Eagle Cere


I am a licensed Wildlife Rehabilitator who is legally in care of two injured female adult Bald Eagles. While they were housed together, one of the eagles managed to entirely remove the cere of the other. They have since been separated and no complications seem to be taking place to the injured bird, however she was slated to be released in a few weeks. My research suggests the cere will not grow back, however, as long as infection does not take place, once the wound heals the eagle should be releaseable. Is there anything I should be specifically doing to aid in the healing process? And overall will a missing cere lead to survival concerns in the wild?
Thank you greatly for your time.

Dear Brian

Thank you for your question.

I have tried to look for information for you, but I couldn't find any. I suspect that as long as the beak isn't infected, the eagle will be able to thrive without a cere. I have seen several pigeons that manage to get about with missing toes and sometimes feet, so I don't think the eagle will suffer, although it may be prone to beak infections.

I'm sorry I couldn't help more.

All the best

I can answer questions about wild mammals and other animals, as well as extinct animals and zoos. I am not an expert about every animal species. I can look up information from books and the internet, but can't verify if all the information is true. Please don't ask questions about: 1. Pets. I am not a vet. Please contact a vet if your pet is ill. You may need to spend some money if you want your pet to live. Don't get a pet if you don't know how to look after it and if you can't provide it with the space, food and possible companions that will help it live a healthy life. Don't take animals from the wild, unless they are ill and/or injured and you can protect them until a wildlife charity can help. It is cruel to take animals from their parents, especially if the parents will look for the babies, while putting their other babies at risk. You may be breaking the law by keeping wild animals or you may need a licence to look after some species. Please check with a local wildlife group. 2. Eggs: Please don't remove eggs from nests. The mother birds provide the right temperature for the eggs and won't sit on them if the temperature is warm enough for them to develop naturally. It is illegal to remove eggs of some species and, unless you have an incubator or a broody hen, the egg may not develop. If you are allowed to touch the eggs, you can candle them to see if they are fertile. If theys aren't fertile, they won't hatch. 3. Fights: Please don't ask about fights between different animals. These questions assume that individuals of two species fight each time they meet and that one species will always be victorious over another. This is untrue. There are cases where a live mouse has been fed to a venomous snake, bitten the snake leading to the snake's demise. 4: Diseases: Please ask doctors or other medical experts about diseases that you may catch from animals. I can't advise on how to deal with viruses, bacteria etc.
