仙八色鸫繁殖习性及雏鸟生长的研究

On Breeding Habit and Nestling Growth of Lesser Blue-Winged Pitta

在安徽紫蓬山区国家级森林公园，对仙八色鸫的繁殖生态进行了研究．对繁殖生境选择、种群密度、巢及卵的特征、雏鸟生长模式进行了较为细致的报道，并给出了雏鸟的生长曲线方程．

Breeding ecology of Lesser Blue-winged Pitta ( Pitta nympha nympha ) was observed in Zipeng mountain national forest park,Anhui province, from April to July in 1996.The birds tended to choose broad leaf forests on hills as breeding habitats, in which the population density was 0.32 ind./hm 2. The nests are global in shape built on the ground among bushes in late May ,with the opening at one side. Eggs are short wide oval in shape,pale brown white in colour, layed in early June , with brown specks. Average clutch size is 5.7 eggs. Incubation period lasted about 12 days. Parental care period lasted 13～14 days. Both incubation rate of eggs and nestling suruival rate were high. Logistic equation of the growth of body weight is W =65.3/1+e-0.471 ( t -5.73) .
