I watched a crow in IA raid a robin’s nest repeatedly and fly off each time (4 times) with a nestling, probably to feed its own nestlings. Poor robin parents harassed the crow each time, but not much they could do. That was the end of that nesting effort. Presumably they started over. Common behavior for corvids.

The crow repeatedly jabbed at the mammal, picking it up and dropping it. The vole attempted to scramble away, but was apparently maimed by the initial thrust. The crow repeated the attacks multiple times and finally flew off with the critter.

The Grackle was hopping around on the ground and the Crow flew down on top of it. There was a struggle but the Crow won. After the Crow flew off I checked and the Grackle was still breathing but not able to move." “I have never seen this sort of behavior before or even heard of it - have you??” Lynn Has anyone had any similar experiences? Thanks, Chris Chris A. Blakeslee Centennial, Colorado <mailto:[email protected]> [email protected] P.S. Lynn added, some people have said to me — "Can I borrow your Crow to take care of the Grackles in my yard?" :-) -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
