This is a common bird in Southern India, and is an active bird throughout the year.
Its calls are like 'kutroo...kutroo' and is pleasant to hear. Usually when one starts to make calls, others also join and start calling one after the other. That is, if there are two birds in the surrounding both make calls alternatively. Even when I am writing this, I am hearing them! May be because of its 'kutroo..' calls, in Malayalam it has a name - 'chinna-kutturu-van'.
How to spot them and photograph:
These birds feed and perch on trees with fruits and seeds, like Mulberry, Jungle Jack (Anjili), Teak, papaya etc.
Since their color is green, it is difficult to spot them between the green leaves. So it is better to look them on Teak trees as their leaves are not so thick. All these pictures were taken when the bird was perched on Teak branches. And in the first and third pictures, I got blue sky as the background as it was sitting on a remote branch - there was no distractions. Even though the bird is active from dawn to dusk, it is better to look for them from morning 6 to 8 (on teak trees especially).
Planting such trees more will be helpful for these birds (not these bird alone, a lo of birds). These birds doesn't like rubber trees (from my observation) and I think cutting of native trees for rubber and other plantations has affected them. So the solution is to retain the native trees between plantations - don't vanish them completely from an area.
The bird makes a flapping sound while flying. Its flight is interesting. After a few flaps, it folds the wings and move swiftly like an arrow, again a few flaps to attain the lost momentum, again fold.. and so on (Sunbirds and other small birds also do this).
