【摘要】 <正> 黄胸鵐(Emberiza auraola Pallas)是一种数量较多的小型候鸟,在我国的东北、内蒙以及苏联、蒙古、朝鲜和日本等地繁殖。于我国广东南部,以及中南半岛、印度一带越冬。每年进行一次南北的往返迁徙,途经我国东部各省。无论春季或秋季,它们迁飞到各地的时期,恰是那里农作物播种与成熟季节。结成大群的黄胸鵐在农田中啄食很多谷物,对农业有严重为害。研究黄胸鵐的食性具有重要的实践意义。对其春秋迁徙时期的食性曾有过报导(寿振黄和刘治庭,1940;刘栭和田鉴明,1959),而关于越冬及繁殖时期的食性却未见过报导。因此,进一步研究黄胸鵐生活中各个时期的食性,对探讨它们的经济意义是很有必要的。更多还原

【Abstract】 From an examination of 859 stomachs of the yellow-breasted bunting (Emberiza auraola Pallas) from Hainan Island, Wuhan, Peking, and Nunkiang in Heiluakiang province, we have found that the vegetable food occupies 88.64% (crop seeds 69.98%; grass seeds 18.66%), while the animal food amounts to only 11.34%.. Although they often live in different localities under different ecological conditions and in different seasons, the kinds of food they take are quite alike, with crop seeds, especially rice and wheat, constituting the major item. They feed on insects only during their reproductive period.更多还原
