The vultures here have no voice boxes, I like em, they only eat dead things instead of killing to eat like most birds humans and scientesters, they don't do nests and they clean up some of the highways.
BTW, the chickadees here are eating up a ton -actually knocking most seeds to the ground where the 'dark eyed juncos' are cleaning up some.
Caa, caaa! Chirp,chirp...
