THE ANHINGA OR SNAKE BIRD


THE Snake Bird is very singular indeed in appearance, and interesting as well in its habits. Tropical and sub-tropical areas where it is a regular summer resident, are its known haunts. It is recognized by different names, as Water Turkey, Darter, and Snake Bird. The last mentioned seems to be the most appropriate name for it, as the shape of its head and neck at once suggest the serpent. It is also called the Grecian Lady, Water Crow, and Bec a Lancette.

It often swims with the body entirely underwater, its head and long neck in sight like some species of water snakes, and has no doubt more than once left the impression on the mind of the superstitious sailor that he has seen a veritable sea serpent, the fear of which lead him to exaggerate the size of it.This bird so strange in looks and action is common in summer in the South Atlantic and Gulf States, frequenting the almost impenetrable swamps, and is a constant resident of Florida.As a diver the Snake Bird is the most wonderful of all the Ducks. Like the Loon it can disappear instantly and noislessly, swim a long distance and reappear almost in an opposite direction to that in which naturally it would be supposed to go. And the ease with which, when alarmed, it will drop from its perch and leave scarcely a ripple on the surface of the water, would appear incredible in so large a bird, were it not a well known fact.It has also the curious habit of sinking.

The nests of the Anhinga are located in various places, sometimes in low bushes at a height from the ground of only a few feet, or in the upper branches of high trees, but always over water. Though web footed, it is strong enough to grasp tightly the perch on which it nests. This gives it a great advantage over the common Duck which can nest only on the ground. Sometimes Snake Birds breed in colonies with various species of Herons. From three to five eggs, bluish, or dark greenish white, are usually found in the nest. The Anhingas consist of but one species, which has a representative in the warmer parts of each of the great divisions of the earth. The number seen together varies from eight or ten to several hundred.When asleep the bird stands with its body almost erect. In rainy weather it often spends the greater part of the day in an erect attitude, with its neck and head stretched upward, remaining perfectly motionless, so that the water may glide off its plumage. The fluted tail is very thick and beautiful and serves as a propeller as well as a rudder in swimming.

I was searching for some information on this wonder bird I saw and photographed in Ranganathittu. Above is the details I got about the same. Thought of sharing it with you :)

Great info srik. As usual.

Looks like this gives the missing link when reptials evolved into land animals.

Keep the zoological and botonical posts coming.

Anand,
This is a fabulous bird and many things in nature are as cryptic and wonderful as it.

mohan,
I'm not an expert, but a learner. An enthusiast aste. I like to collect such information and relate with the things I see around.

Yes, birds are the link between reptiles and mammals in the evolution cycle.
Amphibion birds are the ones that emerged out of reptiles, with sheer interest in flying, I guess!!

that's one big advantage of living in the tropics, we get to see many rare species. despite the hot and humid weather, the never-ending downpours, these fauna survive!!
