Genus DICAEUM

The genus Dicaeum contains eight species of Indian birds, which are characterized by the possession of nine primaries and a slender bill with the lower line of the inferior mandible nearly straight.

In Dicaeum the males of many of the species are brightly coloured, and in these cases the sexes differ in coloration ; in other species they are more dully coloured and the sexes are alike.

They are all without exception of very small size. They frequent trees, generally at a considerable height above the ground, and feed both on insects and small berries. Their nests are beautiful structures made of the finest and most delicate materials, egg-shaped, and suspended from the tip of a branch. They all lay white eggs, so far as is known.
