Brachypodius cinereoventris BJyth, J.A.S.B., xiv, p. 576 (1845) (Tippera). Micropus cinereiventris. Blanf. & Oates, i, p. 295.
Vernacular names. Dao-bulip-garaju (Cachari).
Description. This bird differs from M. m. melanocephalus in having the breast, upper part of the abdomen, hind-neck and sometimes the upper back bluish grey instead of yellow or green.
Colours of soft parts and Measurements as in that bird.
Distribution. The same also as in that bird but apparently not extending to Siam, Annam, or Sumatra and the other islands,
Nidification and Habits exactly the same as those of the Black-headed Bulbul. It is generally found in company with flocks of the Black-headed birds and, as far as my experience goes, never by itself, though every flock of the former may not necessarily contain any of these with grey abdomens. The Cachari names for M. melanocephalus and M. cinereoventris mean male and female of the same species but, as I have already shown, the difference is not one of sexes though the two birds are probably dimorphic forms of the same species. Two pairs of eggs in my collection measure 21.4X15.4; 21.0x15.1 and 23.4x16.1; 22.4x17.0 mm. The latter appear very large for the size of the bird.
