There are large predators such as leopards, lions, hyenas and cheetahs. These predators are attracted to the masses of easy prey.

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.
