Very informative visit, worth dropping by
Polar Bears International的点评
点评：Given that we were in this part of Manitoba to see polar bears it made sense to visit PBI and learn about the iconic bear of the Arctic. This nonprofit aims to “provide the best available science to governments, institutions, and policy makers, as well as to the general public” to promote polar bear conservation.
Our docent was Joanna, a polar bear scientist from Norway, which only helped to emphasize the international nature of polar bear conservation and nature conservation as a whole. She showed us the different polar bear populations and how the local conditions affect their behavior. All these bears rely on Arctic sea ice to be able to hunt their favored prey, seal. In regions where sea ice persists to some degree even in summer the bears continue to hunt seal. Other polar bear populations have access to ice from glaciers to maintain access to seal. The polar bears around Hudson Bay hunt ringed seal out on the ice pack during the winter freeze. We learned that the bears strip ringed seal of their thick blubber and leave most of the meaty carcass behind for other non-bear species to feed on. By the summer the ice pack has melted and the bears are forced ashore to survive the summer on fat accumulated over the winter. This is the total opposite of black and brown bears that hunt and fatten up in the summer and hibernate over the winter. Polar bears do not hibernate over summer, however, and live offbut simply rest conserve fat and energy by minimizing unnecessary activities.
The PBI building is small but very informative. Their severely raised research tundra buggy was parked outside. This is not the same buggy used by visitors to Churchill in the early winter months when viewing polar bears gathering close by as well as within Churchill.

翻译：既然我们来到马尼托巴省的这个地方是为了看北极熊，那么参观 PBI 并了解北极的标志性熊是有意义的。这个非营利组织旨在“向政府、机构和政策制定者以及公众提供最好的科学知识”，以促进北极熊的保护。
我们的讲解员是来自挪威的北极熊科学家 Joanna，这有助于强调北极熊保护和整个自然保护的国际性质。她向我们展示了不同的北极熊种群以及当地条件如何影响它们的行为。所有这些熊都依赖北极海冰来捕猎它们最喜欢的猎物海豹。在海冰持续存在到一定程度的地区，即使在夏天，熊也会继续捕猎海豹。其他北极熊种群可以通过冰川获取冰块，以保持对海豹的捕猎。哈德逊湾周围的北极熊在冬季结冰期间在浮冰上捕猎环斑海豹。我们了解到，熊会剥去环斑海豹厚厚的脂肪，留下大部分肉质的尸体供其他非熊类物种食用。到了夏天，冰层融化了，熊被迫上岸，靠冬天积累的脂肪度过夏天。这与黑熊和棕熊完全相反，黑熊和棕熊在夏天捕猎和增肥，在冬天冬眠。然而，北极熊不会在夏天冬眠，而是靠休息来生存，通过减少不必要的活动来保存脂肪和能量。
PBI 大楼很小，但信息量很大。他们精心打造的研究用苔原车停在外面。这与初冬时节游客在丘吉尔观看北极熊聚集在附近以及丘吉尔内部时使用的车不一样。
