An eagle eats its brother in front of its parent

Cainism is the killing of cubs in a brood (usually the older and stronger ones) by their own brothers and sisters. It is common in birds and, as a rule, is connected with understandable ecological reasons. Most species start incubating from the first egg, the clutch lasts several days and the chicks turn out to be of different ages, so the advantage of the older and stronger ones is quite clear.
