'''Mount Murphy''' is a massive, snow-covered and highly eroded shield volcano with steep, rocky slopes. It is directly south of the [[Bear Peninsula]] in [[Westarctica]]. The mountain is bounded by the [[Smith Glacier|Smith]], [[Pope Glacier|Pope]], and [[Haynes Glacier]]s. Its lower slopes terminate at the [[Crosson Ice Shelf]].
The '''[[Brown Skua]]''' is a large seabird that breeds in the subantarctic and [[Antarctica|Antarctic]] zones and moves further north when not breeding.


Mount Murphy was delineated from aerial photographs taken by [[U.S. Navy]] Operation Highjump in January 1947. Named by US-ACAN for Robert Cushman Murphy of the American Museum of Natural History, noted authority on [[Antarctica|Antarctic]] and sub-Antarctic bird life. While serving on a [[whaling]] ship, he charted the Bay of Isles region of South Georgia. During a 1968 biological survey of [[Marie Byrd Land]], Mount Murphy was one of the few locations where [[snow petrel]]s were discovered. In addition to the petrels, the survey team also found algae.

The Brown Skua is a large seabird that breeds in the subantarctic and Antarctic zones and moves further north when not breeding.

Brown skuas are masters of piracy, they often feed by stealing partially digested fish from the the beaks of other birds. Their victims are typically terns or penguins, though other fish-eating species are also pursued until they disgorge their catches. The fact that skuas are swift and agile fliers (and that they sometimes gang up on a single victim) aid in their success rate. This is the heaviest species of skua and rivals even the largest gulls as the heaviest species in the shorebird order although not as large in length or wingspan.
