Population Dynamics of the Black-capped Chickadee

Abstract

The Black-capped Chickadee is an abundant, familiar bird in Wisconsin, known to almost everyone. In summer it is widespread in nearly all kinds of woods, although it is more numerous in younger second-growth forests, swamp forests or along forest-edges than in mature climax types. In winter, it becomes more restricted to dense thickets, bogs or swamps, especially where conifers like cedars or hemlocks occur; however, it also congregates in large numbers in towns or suburban areas wherever it can find artificially provided food at bird-feeding table. ecology. Since 1968 we have been concentrating our efforts more and more on a year-round study of Chickadee population dynamics.
