Golden eagle

Like most large birds of prey, Golden Eagles breed rarely, and usually lay only two eggs per nest. It might be due to their deadly and wild nature..

Often, one of the eggs hatches with a few days of advantage, and the firstborn chick starts being fed before its sibling is even born.

Due to this, the firstborn grows bigger and stronger than the younger chick, and usually wins most squabbles for food.

If food is very scarce, the younger chick can eventually become weak and is likely to die because of malnutrition. Scientists believe that up to 80% of all second born Golden Eagle chicks die like this.

If food is extremely scarce, the ever-hungry firstborn will actively kill and devour its younger sibling in the nest, without its parents doing anything to prevent the fratricide.

This provides a valuable meal for the stronger chick, as well as reducing the workload for the adult eagles . it is always easier to feed one single chick than two.

Fratricide has been reported in other kinds of raptors, such as the Bald Eagle, but it doesn’t seem to be as frequent as in Golden Eagles.
