Hibernation: GARTER SNAKE – This species is very much awake, but when temperatures get too cold, they go into an inactive state and their metabolism slows down., BUMBLEBEE – Only the Queen goes into a state of long sleep for the winter. The rest of the worker bees actively keep the nest warm and safe., PRAIRIE DOG or GROUNDHOG – In the fall, prairie dogs put on a layer of fat to help them survive in the winter. When the weather is cold or snowy, they may go into a light sleep-like state and stay in their burrows for a few days., CHIPMUNKS – Chipmunks don't sleep all the way through the season. They retreat to their burrows but wake every few days, raise their body temperatures to normal, feed on stored food rather than fat reserves, and urinate and defecate., BLACK BEAR – Black Bears sleep up to 7 ½ months without eating, drinking, urinating, or defecating. During this sleep, the animals will not wake up when they hear a loud noise or even if they are moved or touched., Migration: SALMON – The salmon run is the time when salmon, swim from the ocean, all the way to the upper reaches of rivers where they spawn (reproduce) on gravel beds. After spawning, all Pacific salmon and most Atlantic salmon die, and the salmon life cycle starts over again., MONARCH BUTTERFLY – The monarch is the only butterfly known to make a two-way migration as birds do. Unlike other butterflies, monarchs cannot survive the cold winters of northern climates. Some fly as far as 3,000 miles to reach their winter home in Mexico and Southern California., PENGUINS – The changes in temperatures, the changes in food availability and the need to mate, among other factors, make many animals move to other areas. This is practically a life-or-death event because the trip is usually long, tiring and full of difficulties, and for juvenile and old penguins, it is especially dangerous., ZEBRA – Each year thousands of zebras move in search of greener grazing pastures. They are a small part of millions of animals making an annual trek for better food and water supplies when grazing land dries up from seasonal drought., SIBERIAN CRANES – Cranes fly over 3,000 miles between their breeding and wintering grounds in Siberia and China. Traveling is the most dangerous time for cranes, due to habitat loss along flyways, power-line collisions, and shootings, BUFFALO/BISON – In the past, bison, would travel for hundreds of miles as they searched for food in the winter. They would follow the same route every year, wearing paths in the soil. During the winter season, bison head to lower ground in the north area of Yellowstone. The snow and temperatures are milder there, and it's easier to feed on grass under the snow., RED CRAB – Every year, millions of Red Crabs travel across Christmas Island in the Indian Ocean to mate. Their journey from forest to coast begins in the rainy season and is protected by park rangers, who block off roads and build temporary fences along the crab's migration path., TORTIOSE – The further turtles are away from the equator the sooner and the longer they take a winter “nap”. The closer to the equator means it’s warmer and the turtle may not sleep. Sea turtles do not hibernate. They migrate to warmer tropical water to stay in during the winter., HUMPBACK WHALE – During the warm season, whales migrate to cold waters where food is abundant. When the weather becomes colder, the food start to scarce and whales migrate to warmer water for mating and breeding., Both: BAT – When insect prey becomes scarce during cold month, this species can often be found clustered on cave walls or ceilings, curled up like furry little balls in a dormant period. HOWEVER, some species choose warmer areas with more abundant food supply.,
