英文摘要 | Black-crowned night heron nests colonially with little egret and cattle egret in Taiwan. The breeding season starts from February to August. The breeding cycle includes (1) male eatablishing territory (2) courtship, nest-building, and copulation (3) egg-laying, incubation, and caring for young (4)Young being independent (5) migration to south. The various behaviors are used at specific stages of breeding. Stretch and snap displays are used frequently at an unpaired heron. When the paired stages develops, ritualised antagonisms and mutual preening become more frequent. During the parental stages, the courtship behaviors fade repidly. Both sexes take incubation. Incubation starts with 1st or 2nd egg. Eggs hatch asynchronous. Both parents feed and care for young. Young is fed by requrgitation into bill of nestling while small, later into bottom of nest. During September, adults and young fly southward over winter and back around February next year.(Summarized by Jin-Yuan Wang) |
