Black-billed Magpie

Black-billed Magpies are slightly larger than jays with much longer, diamond-shaped tails and heavier bills. In flight, their wings seem to be too short to support their graceful flight.
These birds are black and white overall with blue-green iridescent flashes in the wing and tail. The upperparts are mostly black with a white patch in the outer wing and two white stripes (“backpack straps”) on the back.
