For years I have been hearing the calls of these birds without knowing how they looked. Information from various web resources tell me that these birds came from Thailand and have made Singapore their home.
The males are black and could be mistaken for crows. I read that these birds sometimes lay their eggs in the nests of crows with the latter hatching and raising the baby birds without a clue about their true identity till they are old enough to leave the coop.
These photos were taken of two male birds (apparently the females are brownish in colour with white specks on their feathers) hiding in the branches of a very tall Norfolk pine in the vicinity of Venus Drive.Now see the video clip:
