Hawk's are amazing predators... Sorry about the crow - - the crying would have gotten to me too. And like you I would have known it was part of life's cycle.
I have several bird stories... here's one: My backyard ends at a saltwater stream - beyond is mangrove. Several times a year poisonous snakes come into the yard while I'm out and the birds go nuts.
At first I thought they were just calling to each other - and that is a part of it - but they make a point of starting up the squawking if I step into an area with a snake. Even going as far a dive bombing the critter if I continue. I do put out water for the birds - and many are regulars. I've had a cardinal family for over 20 years. They winter here... Maybe they see me as member of the tribe. Or entertainment. Who knows - but I'm grateful for their protection.
Haha...I think they WERE protecting you.
They know who their enemies and friends are!
