A Yellow-bellied Sapsucker hangs out on a birch tree in St. Vital. The Yellow-bellied Sapsucker is considered a keystone species. Other species take advantage of the holes that the birds make in trees. A group of sapsuckers are collectively known as a "slurp" of sapsuckers. April 24, 2012 BORIS MINKEVICH / WINNIPEG FREE PRESS
