They are birds. mammals are covered with hair and give live birth and feed them from mammary glands (cows, people, cats, dogs, horses, etc). birds lay eggs and feed their young with bugs and worms.

Mammals and birds are both in the same phylum (Chordata) because they share common characteristics such as the mineralization of their vertebral column, a distinct region of the head where the senses are mainly perceived and have a closed circulatory system such like ours with a ventral beating heart. Birds are in the class Aves and mammals are in their own separate class, Mammalia.
bird are not mamals, they are birds.
