Thick-billed murre

Uria lomvia

The thick-billed murre or Brünnich's guillemot is a bird in the auk family . This bird is named after the Danish zoologist Morten Thrane Brünnich. The very deeply black North Pacific subspecies ''Uria lomvia arra'' is also called Pallas' murre after its describer. The genus name is from Ancient Greek ''ouria'', a waterbird mentioned by Athenaeus. The species term ''lomvia'' is a Swedish word for an auk or diver. The English "guillemot" is from French ''guillemot'' probably derived from ''Guillaume'', "William". "Murre" is of uncertain origins, but may imitate the call of the common guillemot.

Murres have the highest flight cost, for their body size, of any animal.
