Yesterday evening I found this baby bird in one corner of my house's verandah on the floor. I picked it up and placed it safely in a tray hoping that tomorrow morning its parents will find it (actually I initially suspected it to be a sparrow hatchling). When I saw it today morning I found that it is probably a bird of prey. As you can notice the large long beak and claws.
I'm really confused now what to do with it. Please suggest something.
EDIT
I live in Uttar Pradesh, India.
Its relatively plain where I live. (No mountains or lake nearby)
Temperature: 35-20 degrees Celsius
