Tracking Polar Bears. Tracking Polar Bears. Polar bears are well adapted to life in the cold Arctic environment. Their thick fur and blubber keep them so well insulated that it is actually easy for them to overheat. They also have large paws that help them move around on the snow and sea ice, where they hunt, breed, and den. Similar to how snowshoes allow people to walk across snow without sinking, the large size of the paws helps distribute the bears' weight over a larger surface area. Small bumps covering the pads of their feet and hair between the pads increase traction and help prevent polar bears from slipping on ice. They also have claws, which they use when running or climbing on ice and for gripping prey.
Polar bears primarily eat seals, although they may also hunt young walruses and beluga whales, and occasionally eat other foods such as reindeer, rodents, birds, vegetation, or garbage. Bird Migration. Bird Feeders, Hummingbird Feeders, Feeder Accessories And Bird Baths! | Birdfeeders.Com. The Migration Process Male Ruby-throats will set out first for the coast, followed by the females who will depart approximately 10 days later. The entire hummingbird migration process spans a period of about 3-months. Planes are scheduled to take off at various times to prevent accidents. Hummingbirds follow this same routine during hummingbird migration. If the hummers were to leave all at once and a weather catastrophe would occur, it could likely destroy the entire species. This explains the reason why only a few Ruby-throats will be spotted in the beginning of the hummingbird migration. The remainder of birds will arrive later, sometimes by a span of several weeks.
Once the flowers cease blooming and insects are scarce, sometimes as early as mid-July, hummers start preparing for migration again. To begin their journey home (south) the hummers will follow the same hummingbird migration process as when they travel northbound. Teacher Tap: Electronic Books and Online Reading.
