Caribou herds migrate different distances. Large herds are more apt to migrate long distances, while smaller herds often migrate shorter distances. For example, the Porcupine caribou herd, which contains about 169,000 animals, migrates between summer and winter ranges that are about 400 miles apart. The Central Arctic herd, which contains about 70,000 animals, migrates between summer and winter ranges that are about 120 miles apart.
Although the migration of Blue Jays is an obvious phenomenon, with thousands moving past some points along the coast, much about it remains a mystery. Some jays are present throughout the winter in all parts of the range. Which jays move and which stay put? Although young jays may be more likely to migrate than adults, many adults do migrate. Some individual jays may migrate south in one year, stay north the next winter, and then migrate south again the next year. Why do they migrate when they do? Many people dislike the Blue Jay because it is known to eat the eggs and nestlings of other birds. However, in an extensive study of Blue Jay feeding habits, only 1% of jays had evidence of eggs or birds in their stomachs. Most of the diet was composed of insects and nuts.
