中文摘要: |
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。 |
英文摘要: |
Breeding habits of Buff-throated Partridges(Tetraophasis 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 min(n=18).Nestlings hatched in 24-29 days(n=4).Chicken weight neatly 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. |
