Foolish Guillemot

Widespread on Pacific Coast from Alaska to California, but more local in the east, being found mainly off eastern Canada. This large auk sits upright on sea cliffs, looking like a northern version of a penguin. It swims and dives expertly, but its flight appears labored. For its size, the Common Murre has the most densely packed nesting colonies of any bird species; nests may be so close together that incubating adults are actually touching other adults on both sides.
