They can become particularly vulnerable to starvation during summer months while they wait for thawed ice to return. That bear turned out to probably have been ill.But certainly, vanishing sea ice makes the predators' hunt for seals more difficult.It was once thought that polar bears could go into a kind of walking hibernating state when no food is around, decreasing their metabolic rates and thus their energy requirements. The researchers went there and observed the bears. The specialists will bring provisions as well as medicine to restore the bear's health, NGS24.RU reported.Polar bears are on the International Red List of Threatened Species and in the Red Book of Russia of endangered species. "Local residents were warned to be careful entering the tundra zone of the Talnakh region, where the bear was seen, according to an announcement from the local civil defense and emergency situations ministry on TASS. The animal was first seen by a group of teenagers, who filmed it and posted the video on Instagram, Krashevsky said. Pictures: Maksim DeminovResidents of Rirkaipiy are used to seeing polar bears in close proximity.For several years they have run a Bear Patrol to make sure there is no conflict between humans and the predators.Yet even they admit that having such a ‘crowd’ of polar bears is quite rare.The bears arrived at Cape Kozhevnkov within three or four days. "Polar bears are evolutionary old animals: the species evolved as long ago as some 600,000 years.Fickel points out that the species has seen many warmer periods during their existence, and that they might be able to adjust to a warmer world – as long as there is a healthy seal population, that is.But still, "when I see pictures of big glacial blocks breaking away and the sea ice is retreating, I get worried," Fickel admits.As a scientist, he stresses that we shouldn't go off of gut feelings, but rather reliable data — "and for polar bears, those (data) aren't there yet. He wanders around looking for food. 2020 National Geographic Partners, LLC. There are adult bears, adolescents and mother bears with cubs of different ages’, said Tatiana Minenko, head of the WWF Polar Bear Patrol in Ryrkaipiy. In a study published last October in the journal Polar bears depend on sea ice to hunt. "He is quite young and possibly lost his mother. Find out what's happening in the world as it unfolds.This is just the latest recent sighting of a bear in a Russian urban area, but the last time a polar bear appeared near Norislk was more than 40 years ago, Anatoly Nikolaichuk, head of the Taimyr Department of the State Forest Control Agency, told Russian state news agency TASS. ""They need to be catching a lot of seals," Anthony Pagano, a PhD candidate at UC Santa Cruz said.In total, the bears would have to eat one adult ringed seal or 19 newborn seal pups every 10 to 12 days to avoid starvation, the researchers say.They assume the bears' hunger for food is greater than previously estimated due to a lack of sea ice; that makes the bears have to roam over greater distances to find and kill prey.According to a study by the University of Colorado, the extent of sea ice across the Arctic is decreasing at a rate of 14% per decade.The problem is that many polar bears can't seem to find enough food to satisfy their high energy requirements.Five of the nine bears that were examined in the study lost weight, amounting to approximately 10% of their body mass during the eight- to 11-day period. You'd work up quite an appetite — and get hungrier the more distance you'd cover.Living in the icy Arctic, they prey on fat-rich mammals like ringed seals to sustain themselves in this harsh environment.The iconic animals require 1.6 times more energy than was estimated in the 1990s, researchers at the US Geological Survey, the Alaska Science Center in Anchorage, and at the University of California at Santa Cruz report in the journal "Science. The seals left the rookery in November and there won’t be a top up on food. They were spotted by Travis Wilkinson in July of 2015 just after midnight.
