Amazing Flamingo Facts Flamingos can only eat with their head upside down. Flamingos are the bird with the longest neck and the longest legs compared with body size. Caribbean, Chilean, and greater flamingos are protected under the U.S. Migratory Bird Act of 1918. Flamingos are very social birds. Colonies of tens of thousands of birds are common.
Flamingos have good hearing but little or no sense of smell.
Chick Hatching - Flamingos most often lay one large egg and both male and female take turns incubating the egg by sitting on the nest. Because there are no regular breeding seasons, chicks hatch throughout the year. Newly hatched chicks have gray or white down feathers and a straight red bill. Their pink feathers begin to show after a two or three year period. Nesting - Flamingos build nest mounds made of mud, small stones, straw, and feathers.
