Question:
What material are bird's beaks made up of?


Replies:
Bird have beaks made primarily of a calcium compound. Much like your nails and teeth. According to Pettingill's Ornithology Textbook (1970), the bird beak which is correctly called the manible is an extention of the skull with a modification of the boney material.

I believe they are made of a protein called keratin, which is the same protein of which your finger nails are composed. Peter Faletra Ph.D.

Bird beaks have a base of bone, which remains with a complete skeleton, and are covered with keratin, which gives the color and other details. J. Elliott
