短翅鸲育雏巢穴及其栖息地研究

Research on the breeding,nesting and habitat of white-bellied redstart

2011年3月—2012年10月,采用实地调查、拍照、样线法进行短翅鸲育雏、栖息地研究。结果表明:首次发现16只7♀9♂繁殖期的短翅鸲,证明长青自然保护区大坪片区有比较稳定的短翅鸲繁殖个体。短翅鸲分布区海拔区间1 000～2 700 m;繁殖期偏爱针阔混交林(7只)、巴山冷杉—秦岭箭竹(5只)、坡下部(9只)栖息。短翅鸲一夫一妻制,在当地属于留鸟、晚成鸟;春冬季和夏秋季有垂直迁移习性;每巢都是两只幼雏;巢穴位于坡脚,有较多的巢材;育雏期约16～17 d。

From March of 2011 to October of 2012, the authors conducted a field study on the breed- ing, nesting and habitat of white-bellied redstart by field investigation, photographing and fixed line transect. The investigation shows that 16 white-bellied redstarts with 7 females and 9 males are breeding in Daping dis- trict of Changqing Nature Reserve. These redstarts are distributed among areas with an altitude of 1 000 to 2 700 meters. Seven of them show a preference for mixed area of needle and broad forests in breeding, 5 are found breeding in Abies Fargessi-Fargesia qinling gensis and 9 in slope bottom. White-bellied redstarts are of monogamy, resident birds and altrices and show a tendency of vertical migration during the turn of winter- spring and summer-autumn. The nest, often located at the bottom of the slope and complete with adequate nesting materials, usually has two young birds. The breeding period lasts for about 16 - 17 days.
