The April distribution of murres and prey patches in the southeastern Bering Sea1
Murres were abundant over the continental shelf and scarce over deep oceanic water in the southeastern Bering Sea during April 1978 and 1979. They occurred in scattered flocks and in patches averaging 26 birds·km ‒2 within a 300‐ × 450‐km area. Thick‐billed murres ( Uria lomvia ), the most common sp...
