(2208) Ciconia ciconia boyciana.
The Eastern White Stork.
Ciconia boyciana Swinh., P. Z. S., 1873, p. 513 (Yokohama). Ciconia alba. Blanf. & Oates, iv, p. 369 (part.).
Vernacular names. None recorded.
Description. Differs from the preceding race only in having a larger bill all black or nearly so, and in being rather larger.
Colours of soft parts. Iris rosy-pink with an outer ring of black (Dav. et Ous.). Bill black, in breeding-season tinged purplish at base ; other parts as in the typical form.
Measurements. Wing 620 to 670 mm.; culmen 195 to 222 mm.
Distribution. Eastern Asia from Ussuri and Amur to Japan and Korea. It occurs in Burma, Manipur and Assam, whilst a pair I once saw in Kulna in Bengal had conspicuous black bills and must have been of this race.
Nidification. Apparently similar to that of the Common Stork but its eggs are said to be rather larger, measuring about 75.2 x 58.1 mm. It breeds on lofty trees or occasionally on rocks and probably returns year after year to the same nest.
Habits. Much the same as those of the preceding bird but not so familiar and confiding in its habits. At the same time, in Northern China it is said to frequent villages, where it may occasionally be seen stalking through the streets or perched high up on a minaret or roof, silent and dignified on one foot.
