It is not just human beings who usually undertake a survey before launching a new venture. Even birds are known to carry out survey before finding a nesting place for themselves.

A flock migratory Asian bird has already begun a survey in and around Kankaria lake. The survey is a part of their nesting activity at Kamala Nehru Zoo, popularly known as Kankaria Zoo.

Over 2000 Migratory birds, including Spoonbill, White Ibis, Little Cormorant, Night Heron and Cattle Egrets, have been coming to the zoo for nesting. “Over 2000 birds come to the zoo for nesting. This year, these birds have already begun their initial activities”, said R.K. Sahu, zoo superintendent.

“Before the birds finally come to the zoo for nesting, a group of 10-15 birds comes to the area and carries out the survey about the availability of food and water in the lake. Once this group is satisfies with the facilities, it goes back only to return with a larger group of suck birds”.

According to Sahu, the area is best suited for nesting because of the greenery and a lake with good fish. The water is also suitable for these birds.

The nesting season begins by June 15 and continues till October and November. Birds like Cattle Egret, Little Cormorant and Night Heron come to the zoo by June 15; others like Spoonbill and Ibis come in July. Officials said that two species of Cattle Egret come to the zoo for nesting.

Each bird gives birth to three to four baby birds and at the end of the season, the number of birds at Kankaria becomes around 10,000. These birds come to the zoo from nearby states as the water level in the lakes there goes down drastically. When they come, the birds also use the old nests which were left behind the previous season.
