Summer Tanager:
Cool facts:
The Summer Tanager is considered a bee and wasp specialist. It usually catches a bee in flight and then kills it by beating it against a branch. Before eating the bee, the tanager removes the stinger by rubbing it on a branch. The tanager eats bee and wasp larvae too. It first catches the adult insects and then perches near the nest to tear it open and get the grubs.
Like most birds that migrate long distances, the Summer Tanager puts on large amounts of fat to fuel the long flight. Tanagers arriving in Panama had enough fat to fly an estimated additional 890 km (553 mi).
