Answer 1

Answer:

1) The definition of a bird requires feathers, a toothless beak, wings (usually allowing for flight), and the ability to lay hard-shelled eggs. Meanwhile, mammals have hair, give birth to live young, and the females produce milk from mammary glands — the structures for which the class is named.

2) Different birds have very different beaks. Over many generations, hummingbirds have evolved beaks that are long, thin and well adapted to reach into flowering plants and extract nectar. Hawks, on the other hand, have evolved beaks that allow them to tear meat and eat the prey found in their environment.

(1) There are alot of differences found in birds. The major differences are:

•Colour

•Size

•Shape of the beaks

•Food they eat [they may be herbivores or omnivores]

(2) Each birds' beaks is different based on its surrounding. For example a woodpecker needs a "long and sharp beak" to create a shelter for itself inside the bark of a tree.
