Several velvet-hooded males could often be found picking lawns full of feeder seed scattered by Grackle beaks and wings.

They came and went with the Grackles, perching on trees and washing in the creek like any other member of the flock.

The female Cowbird exhibits a more parasitic behavior.  Declining to build her own home, she’ll lay eggs in the nests of several other species and leave them to be raised by the hosts. [More about this fascinating technique here.]
