My name is Dr. Andrew Sos and I will tell you shortly how to trim a bird's beak. First of all it is very important to point out that if everything is normal you don't have to trim the beak of a bird because it will tear it away if proper food is given and the bird can chew, that is important for it. Usually the need for the trimming of the beak will come out with parrots macows, probably cockatoos so those kind of birds which are not always getting the proper food and the proper amount of chewing material. In my hand this is an injured sparrow so this bird does not need the trimming of the beak but you can see the shape of the beak is very similar to what you would see in a parrot or in a cockatoo so it is very important first to be familiar with what is the normal shape of the beak because that is what you are aiming at and you would like to trim. But it is also very important if you get a bird which has an overgrown beak or a misshaped beak, very often you cannot reach the exact shape of the original bill because there is living an bleeding tissue on the overgrowing tissue so when you clip it always be sure that you have for example baking powder with you or any other kind of material which can stop bleeding and call the veterinarian if you get a crack. The other important thing is if you have a bird which has an overgrown or a misshaped beak always check what can be the problem behind it because this can be for example an unofficial problem or it can be an any kind of internal organ problem for example a liver problem which caused this deformity. So the most important thing is to think in complex and not just the trimming of the beak.
