Functional responses in polar bear habitat selection (2003, background): “may hunt terrestrial prey as birds (Stempniewicz 1993), reindeer (Derocher et al. 2000) and scavenge carrion, but seals on ice are their main prey (Stirling and Archibald 1977, Smith 1980, Gjertz and Lydersen 1986).”
Diet composition of polar bears in Svalbard and the western Barents Sea (2002, unknown): “and scavenging of reindeer (Rangifer tarandus platyrhynchus) (Derocher et al. 2000) attest to the diversity of diet.”
Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “Polar bears feed on ringed and bearded seals and occasionally take belugas, narwhals, walrus, harbor seals (Phoca vitulina), reindeer (Rangifer tarandus), and birds (Smith 1985, Calvert and Stirling 1990, Smith and Sjare 1990, Stirling and Øritsland 1995, Derocher et al. 2000).”
POLAR BEAR DIETS AND ARCTIC MARINE FOOD WEBS: INSIGHTS FROM FATTY ACID ANALYSIS (2008, background): “Although occasional depredation of caribou (Rangifer tarandus) has been documented (Derocher et al. 2000), the nutritional contribution of terrestrially based species appears to be negligible (Ramsay and Hobson 1991, Hobson and Stirling 1997).”
