Chaatak is a Pied Crested Cuckoo bird which is several steps ahead then camel. It is a migratory bird which appears only in rainy season. It has a shrill voice in which he pleads to the clouds to rain water to quench his thirst.It can survive even for months together without drinking water. Why? Because it is a special bird. What is that specialty? That it does not drink water found on earth. It drinks only that water which falls as rain from the sky during Swaati Nakshatra. It will never drink any ordinary water from anywhere even if its throat is cracking with thirst. Even if it is about to die of a parched throat, and around it there are seven oceans, rivers, and lakes overflowing with water still it will not touch that water. It looks only up, mouth agape, for the rain to fall when the star Swaati is in the ascendant. To the Chaatak bird all waters are mere dryness besides Swaati Nakshatra water.

There is a short story related to this - "The Curse of the Bullock" :

Long time ago, there lived an old woman with her daughter in a small village. While the old woman was hard working, her daughter was lazy and selfish. They had a bullock in their house too.
“We should take proper care of our bullock.” The old woman would say.
“Hah! Animals should serve us, not that we should serve them,” the daughter would reply.

Now there was a pond, at some distance from the woman’s house. Every afternoon, that woman used to take the bullock to the pond to have a bath and to make him drink water. Meanwhile her lazy daughter would eat and sleep. One day, the old woman fell ill, so she requested her daughter to take the bullock to the pond.

“It is very hot today, dear! The bullock must be thirsty,” said the old woman. “Look! I have some sweets here. I know you love sweets, dear. Take the bullock for a drink. While he is drinking water, you can eat these sweets,” the old woman added, handing a box of sweets to her daughter. T he greedy girl agreed, but as soon as she was out of her mother’s sight, the lazy girl tied the bullock to a tree and sat down to eat the sweets. The thirsty bullocks waited for the daughter to finish eating the sweets.

“I hope she eats her sweets fast. I am really thirsty,” thought the bullock.
But after having eaten all the sweets, the daughter returned home and lied to her mother that she had taken the bullock to the pond and that the bullock had drank water from the pond. The bullock was extremely angry. He cursed the daughter, “In your next birth, you may be born as a Chaatak, a bird that drinks water when only it rains. As you kept me thirsty today, so you will also remain thirsty.” The curse of the bullock came true. In her next birth, the daughter was born as a Chaatak bird.

It is said that a Chatak is a bird that waits for rains, remaining thirsty throughout the year, despite having water all around.
