'''[[Moore Dome]]''' (74°20′S 111°20′W) is an ice dome, circular in plan and 15 nautical miles (28 km) in extent, rising to 700 meters (2,300 ft) and forming the northwest portion of the [[Bear Peninsula]], along [[Westarctica]]'s [[Walgreen Coast]]. [[Koloc Point]] is at the northern extremity of the coast of the dome.
The '''[[Brown Skua]]''' is a large seabird that breeds in the subantarctic and [[Antarctica|Antarctic]] zones and moves further north when not breeding.


Moore Dome was mapped by the United States Geological Survey from aerial photographs taken by [[U.S. Navy]] Operation Highjump in 1947 and the U.S. Navy in 1966. It was named by the Advisory Committee on [[Antarctic]] Names in 1977 after Captain Robert G. Moore, USCG, Commanding Officer of USCGC ''Burton Island''. The ''Burton Island'' conducted operations in the [[Ross Sea]], [[Pine Island Bay]], and along the [[Antarctic Peninsula]] during the 1974–75 season.

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.
