A magpie () preying on a fledgling of Daurian redstart () was incidentally recorded with a video shot by mobile phone on 26 May 2021, providing direct evidence for magpie predation. It also shows that predation is an important factor that affects the survival of fledglings, indicating that survival of fledglings should be considered in evaluating breeding success of birds. The fledgling was about 13-day-old posthatching, and it was on its first day of leaving the nest when the incident occurred. It was preyed upon by a magpie 10 m away from the nest by two attempts under strong defensive behaviour from the female.
2021年5月26日,一只喜鹊( )捕食一只红尾鸲雏鸟( )的过程被手机拍摄视频偶然记录下来,为喜鹊捕食行为提供了直接证据。这也表明捕食是影响雏鸟生存的一个重要因素,意味着在评估鸟类繁殖成功率时应考虑雏鸟的存活情况。这只雏鸟孵化后约13日龄,事件发生时是其离巢第一天。在雌鸟强烈的防御行为下,它在距离巢穴10米处被一只喜鹊分两次捕食。
