Distribution. The Nicobar Islands of Teressa, Bompoka, Tillan-chong, Camorta, Nancoury, Trinkat, Katchall and Pilu Milu.
Nidification. Unknown but as Davison shot very young birds in February, they presumably lay about November to December.
Habits. 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 is usually seen singly, in pairs, or in small parties of five or six; but I have seen them on several occasions 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 Mynas settling down for the night.''
