About the Ancient Murrelet

The ancient murrelet (Synthliboramphus antiquus) is a bird in the auk family. The English term "murrelet" is a diminutive of "murre", a word of uncertain origins, but which may imitate the call of the common guillemot. Ancient murrelets are called "ancient" because they have grey on the back like a shawl, as worn by the elderly.

The ancient murrelet was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the auks in the genus Alca and coined the binomial name Alca antiqua. Gmelin based his description on the "ancient auk" that had been described in 1785 by both the English ornithologist John Latham and the Welsh naturalist Thomas Pennant. Both authors mention a specimen in the Leverian Museum and give the location as the west of North America, the Kuril Islands and the Kamchatka Peninsula. The ancient murrelet is now one of five species placed in the genus Synthliboramphus that was introduced in 1837 by the German-born naturalist Johann Friedrich von Brandt. The genus name combines Ancient Greek sunthlibō meaning "to compress" with rhamphos meaning "bill"... Wikipedia →
