Vernacular names. None recorded.
Description. Differs from the Indian Little Green Heron in its darker grey plumage, more especially that of the neck, breast and abdomen, which are dark slaty-grey; the sides of the head have less white and are also a deeper grey.
Colours of soft parts as in the preceding bird.
Measurements. "Wing 167 to 171 mm.; tail 58 to 62 mm.; tarsus 41 to 44 mm.; culmen 57 to 60 mm.
Distribution. Andamans and Nicobars.
Nidification. Exactly like that of the preceding bird but the favourite nesting-sites are on the mangrove-trees along the shore, which are partly submerged at high tide. Osmaston, Wickham and Anderson took many nests during May and June in various islands of the Andamans, nearly always built on mangroves in swamps two to four, occasionally eight, feet above high tide. The eggs are indistinguishable from those of the Indian bird but two nearly always form the full clutch. Twelve eggs average 38.2 x 28.2 mm.: maxima 40.6 X 28.7 and 40.1 x 29.9 mm.; minima 36.1 X 27.4 and 36.8 x 26.3 mm.
Habits. Similar to those of the Indian bird.
