Eagle Crushes Bird To Death

One down and a BUNCH to go....I don't like those flying rats.
They'd crap all over our parking lot, street lighting and under overpass lighting so much. Those under the overpasses were so bad you'd have to mask up because the possibility of a bad lung infection (fungal, IIRC).
 
Isn't that a Red Tail Hawk? Those Mockingbirds are pretty brave, trying to save that pigeon. I've seen Mockingbirds trying to save another Mockingbird from hawks before, but not trying to save another type of bird before.
Could be that the mockingbirds are nesting right now, so they go after anything that's in their zone...we've got bluebirds on a nest as we speak. And they're some barn swallows with hatchlings outside our fav local restaurant overhanging eaves.
 
Reminds me of a black magpie / crow / raven or something that I saw land on my roof with what looked like a dinner roll it had stolen from someone's picnic. Pretty sure it flew away and other birds came and ate the bread.
 
Now it makes sense. I wondering the same thing as @bp2008. That is, why the eagle left without taking its kill?
It seemed awful cruel to kill just for the fun of it (only humans do that)
Well, cats do the exact same thing, along with weasels, honey badgers, jaguars, orcas, red foxes, leopards, lions, spotted hyenas, brown bears, American black bears, polar bears, coyotes, lynxes, minks, raccoons...........
 
I once saw a hawk snatch an ibis in about 8 inches of water the hold the ibis underwater until it drowned then flap-drag it's limp body to shore to have breakfast.
