Why do you suppose cainism is so much more common in booted eagles

Because god always gives more fucks about one booted eagle or hawk sibling than the other. Or something. I don't fucking now.

Just anticipation of a harder life

Well of course, learning basic survival skills is crucial. I'm just wondering why it seems to be less common in sea eagles, particularly Stellar's sea eagle and the bald eagle. I've been watching nest cams for a few years, and while I've seen some brutal sibling rivalry, it's never resulted in death. They've died of illness, or starvation, but never direct killing and cannibalism.

They seem to be more docile.
