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)
