Our Winter Bully - The Mockingbird

Mockingbirds from all I've read are known to guard bird feeders but normally if there is a suet block out.  We don't normally put out suet but our bird seed mix does include nuts.  Maybe that's what our "bully" is guarding.

He chases the tits, chickadees, and other small birds away when they land on the flat feeders but doesn't intimidate the larger birds like the cardinals and blue jays.

This is a sketch from this morning while watching him where he perches as he guards the feeders.
