Lesser flamingos (Phoenicopterus minor) are the most numerous of the flamingos, and the greater flamingos (Phoenicopterus roseus) are the most widespread. In India I often see flocks of lesser flamingos mixed in with a few greater flamingos. I found early on that the easiest way to tell them apart is by looking at the shape of the neck when it is relaxed: the neck of the lesser looks like an inverted letter J, and that of the greater like an S.
Flamingos are common across western India. I’ve been delighted more than once to look out of my window and see a flock flying past in the distance. Still, they are weird enough that it is always a delight to watch them. They stand around in groups, like humans, but in constant motion. Like humans they keep doing their own thing in groups: now walking away from the group, then joining up and walking with another bunch. All through this they constantly keep honking at each other.
We came across a bunch of them in a shallow pond in the Rann of Kutch. They were all active (not a single one stood on one leg, dozing with half a brain turned off). Although a small hamlet had grown up on the banks of the pond, I’m sure that the water was salty; flamingos like their water either salty or alkaline. Flamingos dominated the waters, although swifts and a few ducks held their own. The desert may seem like an unlikely place to find these birds, but a big population of flamingos breed in the Rann of Kutch.
The strange shape of their black-tipped beaks helps them to hold their head upside down and sieve water for the small algae, insects, and crustaceans that they eat. The pink of their beaks and feathers come from the molluscs that they eat, so you can tell the juveniles by their lack of colour. I’d seen flamingos numerous times before, but was happy to stand at this place and watch them again; they are fascinating.
