How life began and attracted birds in a lake which was totally dry for years

Muttanalluru Lake,

One of my favorite places around my residence in Attibele where I will be frequenting for birding since 4 years. The lake remained totally dry all these years (Though some small water pockets formed for a short term during rain).  Muttanalluru lake is an excellent habitat for many grass land birds and raptors. A small patch of forest around the lake supports several woodland birds like wood pecker. This lake also hosts good number of migratory bird species.

This lake is also abused with all anthropogenic pressures from near by towns, severely polluting the lake bed with garbage dumping and waste from butcheries. Pesticide pollution is another contributor.

But recent visit to the lake on 20.09.2015 was totally different unlike any other visits. Yes, there was inflow of water to the lake forming large portion of the lake with water. This started to happen just a fortnight before when the area received heavy rain fall on 06.09.2015. 

What exited is this short time of 15 days attracted much of local waders and water birds and they are residents now!

Since there is abundance of food to feed on, especially fish and aquatic insects, it attracted water birds. The question that tickles is from where the fish and other aquatic insects come to a lake which is full dead dry for years? How did the life and nature's arrangements began there in as less as week's time?

The Nature is always mystery is it? It is very complex relationship among species with-in the ecology exists. Every species has a definite role to play in balancing act of nature. In this case, for example the waders (birds) make local migration in search of food from one water body to other. By doing so, they carry the eggs of various aquatic insects, fish which sticks to its legs, feathers etc., from already existing water. These waders when land on the fresh water body, they disperse the eggs and thus distribute the species giving life to new water body. The dispersed species multiplies and attract more birds and create abundance of food supporting other life forms. The flowing water will also contribute to support distribution.

Fruit and seed eating birds distribute seeds from one place to other place making vegetation to spread. Certain animals also helps for dispersal of seeds. The bees and nectar feeding birds/ insects helps pollination. Carnivorous, insectivorous species control over population of those at lower levels of food chain, creating a balance.  This is the Nature's own mechanism of inter-dependency among lives.

The new life begins!!!!

Sunset over Pulicat Lake

Sunset over Pulicat Lake... Birds can be seen as black spots across

Pulicat Lake is the second Largest backwater salt Shallow Lagoon of India making it an excellent habitat for many waders, Hosts Pulicat Bird Santury, and a famous "Satish Dhawan Space Centre" of Indian premier organization "ISRO - Indian space research organization". The place is well known for Indian rocket launches.

Area of the lake varies with the tide; 450 square kilometres (170 sq mi) in high tide and 250 square kilometres (97 sq mi) in low tide. Its length is about 60 kilometres (37 mi) with width varying from 0.2 kilometres (0.12 mi) to 17.5 kilometres (10.9 mi).

Fishing is the major occupation for the villages around Pulicat lake.

**************************************
Coming to Birds, this shallow water habitat makes ultimate destiny for many waders and other aquatic birds. The lake will be in its full glory in winters and an important stop-over for many migratory birds. Its also an Important Bird area (IBA) classified by bird life international.

Every year around 15000 greater flemingos visit here, the entire lake is very rich in fish population hence supporting huge number of birds.

Agricultural and industrial pollution is the biggest threat for this lake
