Breeding and nest building are dependent on the food supply, which is dependent on the amount of rainfall in an area. The female will lay one and sometimes two eggs, which the parents will take turns incubating, and the chicks will hatch about 30 days later. The parents recognize their own chicks by sight and the sounds they make and will only feed their own offspring. The chicks are gray or white in color and are born with a straight bill that curves as they get older. They won't turn pink until they're one, two, or even three years old.
Flamingos have an interesting way of feeding.
If you look at their bill, you'll notice that it is curved downward just below the nostril. This is an adaptation for filter feeding. When they are searching for food, it looks like they are sticking their heads upside down and under water. Actually, they put their open bill in the water and move it from side to side and as the water washes through, there is a tooth like ridge on the outside of the bill that helps it filter or separate the food from the water. They may stomp in the water to stir up the sediment from the bottom of the lagoon.
