According to National Geographic, scientists have an answer for the age old dispute over which came first, the chicken or the egg. Reptiles were laying eggs thousands of years before chickens appeared. The first chicken came from an egg laid by a bird that was not quite a chicken. Therefore, the egg came first.
The first bird domesticated by humans was the goose.
Kiwi birds are blind, so they hunt by smell.
Some breeds of chickens can lay colored eggs. The Ameraucana and Araucana can lay green or blue eggs.
The common phrase "eat like a bird" should mean something quite different! Many birds eat twice their weight in food each day. In fact, a bird requires more food in proportion to its size than a baby or a cat.
A group of larks is called an exaltation, a group of chickens is called a peep, a group of geese is called a gaggle, a group of ravens is called a murder, and a group of owls is called a parliament.
Chickens that lay brown eggs have red ear lobes. There is a genetic link between the two.
Crows have the largest cerebral hemispheres (brains), relative to body size, of any avian family.
Mockingbirds can imitate many sounds, from a squeaking door to a cat meowing.
