Animal migrations from the grand to the miniscule enliven the plains of the Serengeti, one of nature's oldest ecosystems. The wildebeests are known migratory inhabitants, famous for their great surge across the plains in search of fresh grasslands. On a smaller scale and lesser known are the locusts, which also make a migratory journey when resources become scarce. Learn more about the wildebeests and locusts of the Serengeti in this video segment from Nature.
