rhinoceros auklet diet

Diet summary data for Cassin's Auklets, Common Murres, Pigeon Guillemots, and Rhinoceros Auklets from the Farallon Islands. Along the west coast of North America, Common Murres (Uria aalge, hereafter “murres“) and Rhinoceros Auklets (Cerorhinca monocerata, hereafter “auklets“) have widely overlapping breeding ranges.During the breeding season, they also have similar diets at breeding colonies and at sea in Washington and British Columbia (Richardson 1961, Sealy 1973, Leschner 1976, Wilson and Manuwal … /Parent 2 0 R May concentrate on copepods in summer, euphausiids in winter. 46 0 R 47 0 R 48 0 R 49 0 R 50 0 R 51 0 R 52 0 R 53 0 R 54 0 R 55 0 R 1170 0 obj 2021-02-03T21:06:25-08:00 343 0 R 344 0 R 345 0 R 346 0 R 347 0 R 348 0 R 349 0 R 350 0 R 351 0 R 352 0 R Ryan David Carle Rhinoceros Auklets eat primarily small, schooling fish or zooplankton, which they capture by diving and swimming underwater, using their wings for propulsion and feet for steering.
