四川雉鹑繁殖习性初报

Notes on the Breeding Habits of the Buff-throated Partridge

2005～2008年,在四川省雅江县对四川雉鹑(Tetraophasis szechenyii)的繁殖习性,包括巢、卵、孵卵时间、生长量度和日行为节律进行了初步观察。四川雉鹑同时营树上巢和地面巢,以树上巢为主,占68%(n=25);产卵期集中在4月,正常窝卵数2～5枚(n=9),窝卵孵化率为63.89%(n=12);雌鸟在孵卵期每天离巢1次,离巢平均时间(63.0±22.6)min(n=18),孵卵期24～29 d(n=4);150日龄幼鸟的体重接近成体。在繁殖期,四川雉鹑6:30～7:00时从夜栖树上飞下,行至觅食地觅食,17:00时左右返回夜栖地,19:00～19:30时上树夜栖。

Breeding habits of Buff-throated Partridges （ Tetraophozis szechenyii ） were preliminarily observed from 2005 to 2008 at Pamuling Monastery in Yajiang County Sichuan Province. The birds built nests in the tree and on the ground, while 68% of the nests （ n = 25） were in the tree. Most birds laid eggs in April and egg size was 2 - 5（n = 9）. The hatching success rate of 12 nests was 63.89% . The female left nest once a day with duration of 63.0 ± 22.6 rain （n = 18）. Nestlings hatched in 24 -29 days （n = 4）. Chicken weight nearly reached as heavy as the adult in 150-day. The birds flew down from the roosting tree between 6：30 and 7：00 and were back between 19：00 and 19：30.
