Polar Bears Won’t be Satisfied by Terrestrial Foods Alone

According to scientists led by the U.S. Geological Survey has found that polar bears, due to them being forced on shore from sea ice loss, may be eating terrestrial foods (berries, birds and eggs). Though some polar bears have been seen to eat terrestrial foods, there is no evidence that the behavior is widespread. Where it has been documented, their condition and survival rates have declined. In some of the terrestrial habitats that polar bears occupy, those areas were already occupied by grizzly bears. The grizzly bears in these areas are of smaller sizes for their species and are potential competitors. Dr. Karyn Rode says that “grizzly bears and polar bears are likely to increasingly interact and potentially compete for terrestrial resources.”
