Calayan (McGregor); Cebu (Everett, McGregor); Luzon (Whitehead); Palawan (Everett); Samar (Steere). Greater Sunda Islands, China, Japan, Celebes, Amurland. Although in color this species seems to be exactly like B. javanica it is much larger; the length of wing is particularly noticeable and the bill is longer, and deeper. A male collected by Major Mearns measures: Wing, 210; tail, 73; culmen from frontal feathers, 66; depth of bill at posterior border of nostril, 15; tarsus, 54; middle toe with claw, 62. A female from Calayan measures: Wing, 197; tail, 69; culmen from frontal feathers, 64; depth of bill at posterior border of nostril, 13; tarsus, 52; middle toe with claw, 54. Some of the records for B. javanica probably refer to the present species but it is impossible to disentangle them. 147. BUTORIDES SPODIOGASTER Sharpe. NICOBAR GREEN HERON. Butorides spodiogaster Sharpe, Bull. Brit. Orn. Club (1894), 3, 17; Cat. Birds Brit. Mus. (1898), 26, 182, pl. 2; Hand-List (1899), 1, 200; Mearns, Phil. Jour. Sci. (1907), 2, sec. A, 353. Palawan (Mearns). Andaman and Nicobar Islands. "Adult.--Similar to B. javanica, but darker gray on the under surface, which is of a sooty-slate color with a slight tinge of rusty on the abdomen, cheeks and ear-coverts uniform slate-color. It much resembles B. stagnatilis, especially the birds from Flores, but it is not so dingy underneath and has a less shade of rusty on the abdomen. 'Bill black, lower portion of lower mandible, from base to tip, edged pale horny; front of tarsus, toes, and claws brownish green, bare portion of tibia and back of tarsus dirty greenish yellow; naked skin round eye dull green, tinged with yellow in front; eyelids deep green.' (Hume.) Length, 445; culmen, 60; wing, 193; tail, 53; tarsus, 43." (Sharpe.) This species differs from both B. javanica and amurensis in its much darker color, particularly of the under parts which are nearly uniform slate-gray; the white of chin and throat is much restricted and on the fore breast is reduced to a few shaft-lines; all of the wing-coverts are edged with dull rusty buff. The specimen collected by Mearns near Palawan measures: Wing, 165; tail, 58; culmen from frontal feathers, 60; tarsus, 47; middle toe with claw, 50. Genus BUBULCUS Bonaparte, 1854. Non-breeding plumage all white; legs and nails black; primaries and secondaries about equal in length; exposed culmen less than middle toe with claw, the latter less than tarsus. 148.
