Migration Info The Eastern Kingbird is a conspicuous migrant, generally traveling by day in flocks of 10 to 60 individuals. The timing and rate of migration in spring coincide with the availability of fruit in Central America. Unlike most flycatchers, this species feeds primarily on fruit during both fall and spring migrations and during the winter. It is believed that most birds travel directly to the southern portion of the winter range (in central Brazil) until they find fruit-producing Yagrumo Macho trees. This tree is a pioneer species that favors disturbed sites and forest edges. Eastern Kingbirds lead a somewhat nomadic existence as they follow the fruiting of this species, gradually moving north into Central America. On their spring migration most birds follow the east coast of Mexico northward, then fan out across the eastern United States.
