Parasitic Jaeger

Parasitic jaegers are fast, falcon-shaped seabirds that breed on Arctic tundra across northern Eurasia and North America. After nesting they disperse widely over the Atlantic, Pacific and Indian oceans. Adults occur in pale and dark color forms, and breeding birds carry pointed central tail feathers. Their powerful flight enables rapid turns and prolonged pursuits of gulls, terns and other seabirds above coastal and offshore waters. (Animal Diversity Web)

Much of their marine diet is obtained through kleptoparasitism: jaegers chase other birds until they release or regurgitate captured fish. They also hunt insects and small birds and take eggs, nestlings, carrion and other available food. Breeding pairs defend open tundra territories and place their eggs in shallow ground scrapes. Both parents incubate, guard the nest and provision the chicks until they become independent. (Animal Diversity Web)
