Habits, &c. Davison remarks: - "Occurs only at the Nicobars, where it is comparatively common; it keeps to the forest generally, but is also found in gardens, in the secondary jungle, and not infrequently in places where there are only a few scattered bushes; it usually is seen singly, in pairs, or in small parties of five or six; but I have on several occasions seen them in flocks of nearly a hundred. They have a chattering note, very similar to the other Hypsipetes, and when they are in flocks they make nearly as much noise as a flock of Mynahs settling for the night. They breed at the Nicobars ; I shot very young birds in February ; but did not succeed in finding any nests."
