Murre (Common)

female

An abundant, penguin-like bird of the cooler northern oceans, the Common Murre nests along rocky cliffs and spends its winter at sea.
 
They are more manoeuvrable underwater, typically diving to depths of 100–200 ft, and depths of up to 600 ft have been recorded.

 
Some individuals in the North Atlantic, known as "bridled guillemots", have a white ring around the eye extending back as a white line. This is not a distinct subspecies, but a polymorphism which becomes more common the farther north the birds breed. The Murre here is in non-breeding colours as to the Murre in the background is in breeding colours.
