Colony of guillemots on cliff-top watching gull close overhead


Guillemots, or murres as they are known in North America, are among the deepest diving of all birds, more than capable of reaching depths over 150 metres. Diving is for food using their short wings to swim under the water. Guillemots breed in large colonies on coastal cliffs, laying a single egg on a narrow ledge, the rest of the year is spent out at sea. There are only two species in this group: the common guillemot and the thick-billed, or BrĂ¼nnich's, guillemot.
