(2111) Haematopus ostralegus osculans.
THE CHINESE OYSTER-CATCHER.
Haemotopus osculans Swinhoe, P. Z. S., 1871, p. 405 (N. China). Haematopus ostralegus. Blanf. & Oates, iv, p. 245 (part.).
Vernacular names. None recorded.
Description. Similar to the preceding bird but larger and a decidedly longer bill ; the amount of white on the primaries is generally, but not always, less, the first primary seldom showing any white at all on the inner web.
Colours of soft parts as in the typical race.
Measurements. Wing 262 to 280 mm.; tail 101 to 112 mm.: tarsus about 52 to 58 mm.; culmen 80 to 98 mm.
Distribution. Japan, North China to North Burma and extreme Eastern Bengal.
Nidification. Nothing recorded. An Oyster-catcher, which is probably of this race, has been obtained, with its eggs, breeding on an island in the Sunderbunds, but the skin has not been available for comparison.
Habits. This has always been considered to be a Winter visitor only to India but the discovery of an Oyster-catcher breeding in Bengal makes further information on this point desirable. In flight, voice etc. this race differs in no way from the typical form.
