Black-crowned Night Heron 取食, Taiwan

Black-crowned Night Heron, 11/29/2009, Taiwan. 夜鹭（学名：Nycticorax nycticorax），又名灰洼子、夜洼子、星雁、暗光鸟. 夜鹭主要取食蛙类、小鱼、虾等水生动物，偶尔吃一些植物性食物；受到惊吓的夜鹭会把吃进去的食物呕吐出来，经消化或未经消化的食物腥臭不堪，以此作为防卫，也可以从中得到­研究夜鹭食性的线索。( http://zh.wikipedia.org/wiki/%E5%A4%9C%E9%B9%AD )

Christina Riehl studied the diet and foraging behavior
of fledgling Black-crowned Night-Herons (Nycticorax
nycticorax) in a mixed-species nesting colony
of Black-crowned Night-Herons and Snowy Egrets
(Egretta thula) in New Orleans, Louisiana. In 1 of 5
years, cannibalism of nestlings that had fallen or
climbed out of nests was common, accounting for 66
of 94 (70.2%) prey items taken by fledglings. Juveniles
took younger conspecifics by both predation and scavenging.
