Abstract
In 1988-1990, direct measures of reproductive success of individually-marked overbirds nesting in a contiguous forest and adjacent forest fragments in eastern Pennsylvania were observed. The data obtained support the existence of a source-sink overbird population, in which large forests represent sources of production and excess reproductively-mature birds occupy sinks within forest fragments.
