The Flamingos ...


Flamingos are very interesting birds. You know they're not born pink, right? Baby flamingos are a whitish-grey. They turn pink over time because of algae in the food they eat. So this kiddo on the right has some years to go (and lots of eating to do!) before he looks as pretty as that other guy on the left.

They have a funny way of feeding - they eat by holding their bills upside down in the water. See that deep curve on the bill? There's a specially adapted tongue inside the bill that filters tiny food items. In lesser flamingoes, the bill pumps water 20 times a second, while the tongue filters away like crazy!! They need about 60 grams of food a day, so no wonder they feed all the time.

Just in case you were wondering, the flamingo tongue tucked away inside that bill is large, fleshy and has little bristly projections. Yeew? The early Romans thought it quite a delicacy, anyway, and pickled flamingo tongue was on the menu at their parties! I kid you not.

Here are some more birds that have not yet turned fully pink. You can really see the curve of the bill beautifully in this photo. Babies are born without the curved bill, by the way. Strange huh? It takes some weeks for the bills to start curving. Until then, parents feed the chick. Both dad and mom produce a sort of "milk" - well, let's call it milk, even though it is red in colour. Babies store the pigment in their liver, which then gets deposited in their adult feathers as they grow.
You know another interesting thing about flamingo babies? They grow up in creches. Flamingos lay a single egg, on mounds of mud. When the eggs hatch, the chicks join a creche, a sort of group child-care facility which is marshalled by some adults. The adults lead them on foot to fresh water sources, because the chicks can't fly. Mom and Dad come to the creche, find their kid, and do the milk feeding thing. Hah! If only we had that sort of child-care to help Mumbai's stressed out working parents!


Here's a longer range view. These are mature adults, since they're all pink. Flamingos live for 40-50 years, did you know? I found that very surprising, because I always thought birds were short-lived. Goes to show how much I *really* know about birds!


Here's a still longer range photo. Look at the number of birds in the distance! How pretty they must look when they're flying!
