摘要

摘要本文报道了以色列成年雄性红隼(Falco tinunculus)捕食第二年同种鸟的两个独立观察结果。2022年1月22日,在吉瓦特Et自然保护区旅行时,我们观察到一只SY红隼与一只成年红隼空战。他们把SY放在他的背上,SY被成年人斩首杀死,后者继续以乳房肌肉为食。早些时候,2013年1月24日,在拉特伦交界处,有人看到两只雄性在飞行中,它们的爪子锁在一起,互相尖叫。最后,他们迫降,成年鸟在顶部,啄着SY同型鸟。他们在这个位置保持了30多分钟,成年人拔了SY的胸毛,SY不断挣扎,但无法逃脱成年人的控制,最终因受伤而死亡。随后,成人从SY的乳房肌肉中进食。虽然鸟类同类相食是已知的一些Falco物种,这是第一次报道的常见的红隼。

Cannibalism in common kestrel (Falco tinnunculus)

Abstract

We report two separate observations of adult male common kestrel (Falco tinnunculus) killing and feeding upon second-year (SY) conspecifics in Israel. On 22 January 2022, while touring the Givat Et Nature Reserve, we observed an SY kestrel locked in aerial combat with an adult. They landed with the SY on his back, who was killed by decapitation by the adult, who continued to feed on the breast muscle. Earlier, on 24 January 2013, in the area of the Latrun Junction, two males were seen in flight with their talons locked together and screeching at each other. Eventually, they crash-landed with the adult on the top and pecking at the SY conspecific. They remained in this position for more than 30 min with the adult plucking the breast feathers of the SY who struggled incessantly but was unable to escape the hold of the adult and eventually succumbed to the injuries. The adult subsequently fed from the breast muscle of the SY. Although avian cannibalism is known in several Falco spp., this is the first reported for the common kestrel.

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
