Kolleru Bird Sanctuary Series - Post 2

Abode for the migratory birds and an interesting destination for the bird lovers.

<Continued from the Post 1>

Encroachments in the form of few paddy fields, numerous fish-farming tanks and human intrusion have increased the pollution, imbalanced the ecological diversity and ultimately influenced adversely the rainfall pattern in the region.

Rich in flora and fauna, it attracts migratory birds from northern Asia and Eastern Europe between the months of October and March. During this season, the lake is visited by an estimated two million birds.

The resident birds include grey pelicans, Asian open-billed storks (Anastomus oscitans), painted storks (Mycteria leucocephala), glossy ibises, white ibises, teals, pintails and shovellers. The migratory birds include red-crested pochards, blackwinged stilts, avocets, common red shanks, wigeons, gadwalls and cormorants, garganeys, herons and flamingos.

Family Tree..!!!

Interesting bird-habitat found at Pragathi nagar lake, currently being dominated by the Painted storks and Geese.
I am still trying to understand the seasonal behavior and migrating habits of the tropical birds.. Surprised to see the increased  population of storks and Geese at this Bird habitat, which used to be dominated by the Ibis, Cormorants, and Egrets..

We fly in a "V"..

Why Do Birds Fly in a V? - It is understood that the “V” formation of a flock  influences  aerodynamics, making it easier for the birds to fly. As the birds flap their wings, the air flowing off their wing tips gives birds in the back of the V an extra lift. This reduces the amount of energy the birds need to fly.

Over the course of the migration, birds take turns leading the front of the V, the most difficult position. When a bird has tired of leading, it falls to the rear of the V, where there is the least wind resistance.

Rotating through various positions in the V maximizes the use of each bird’s energy, allowing flocks to fly for long periods of time without having to stop.
