基于红外相机监测的黄喉鹀育雏行为
2019年4—7月,在黑龙江中央站黑嘴松鸡国家级自然保护区生物多样性监测样地(50°47′50″—50°48′6″N,125°55′14″—125°55′40″E;海拔47350—53079 m)内,利用红外相机对5个黄喉鹀(Emberiza elegans)繁殖巢进行视频监测,共记录到3358条有效视频。分析表明:营巢期为(67±12)d,窝卵数为(52±05)枚,孵卵期为(127±12)d,雏鸟留巢时间为(117±06)d;雌鸟每日平均喂食频次略低于雄鸟,但频次差异不显著(P>005),喂食总频次(y1)与雏鸟日龄(x1)呈正相关关系(y1=50839x1+4...
