THE EASTERN GREY PLOVER.
Charadrius hypomelas Pallas, Reise Russ. Reichs., iii, p. 699 (1776) (East Siberia). Squatarola helvetica. Blanf. & Oates, iv, p. 236 (part.).
Vernacular names. Barra batan (Hind.).
Description. A slightly smaller bird and distinctly more grey, less brown in the non-breeding plumage.
Colours of soft parts as in the typical form.
Measurements. Wing 175 to 193 mm.
Distribution. Eastern Siberia to Japan. In Winter South to Australia, Tasmania, South China and Burma. The Assamese birds seem to be of this race and they almost certainly occur in Eastern Bengal.
Nidification. Nothing recorded.
Habits. Similar to those of the preceding bird. I found this race common in Assam, migrating South in the last few days of September and North at the end of March and early April. In most instances they were in small flocks of ten to twenty birds but on one occasion I shot a male in full breeding plumage from a flock of many hundreds, all apparently of this species. They were feeding in a ploughed field and rose a good hundred yards in front of my companion, whistling shrilly, but wheeled and gave me a long shot in so doing. This bird's stomach was full of a small black and very hard beetle.
