Incidental Observations of the Brown Bear (Ursus arctos Linnaeus, 1758) and the Red Fox (Vulpes vulpes (Linnaeus, 1758)) on the Coast of the Chukotka Peninsula

Incidental observations of the brown bear and the red fox were carried out during 7 field seasons (2003–2009) on the coast of the Anadyr Bay of the Bering Sea – the Meeskyn Spit Island and the Retkyn Spit in the vicinity of the Pacific walrus haulouts. A total of 112 brown bears have been recorded. The largest number of meetings took place from mid-July to the first half of August. The usual behavior of brown bears is searching and foraging. In July and early September, the bears ate dead marine mammals, mussels and berries. Usually brown bears avoided meeting humans, in some cases they were not afraid and came close. Observations of a brood (one puppy) of a red fox were carried out during one season. Observations have shown that the molt of the female and the puppy occurs a month later than in central Russia. The data of the current abundance of brown bear and red fox are given according to the official data of the Department of the Chukotka Autonomous Okrug.
