BIRD OF THE WEEK
SCIENTIFIC NAME: Setophaga pensylvanica
POPULATION: 18 million
HABITAT: Breeds in second-growth deciduous forests and shrubby clearings created by forest fires and other types of ecological disturbance. In winter, found in humid tropical forests and edges.
Chestnut-sided Warbler was not well known before the 1800s; prominent ornithologists such as Audubon and Wilson seldom saw the bird and knew little about it. Like the Golden-winged Warbler, this bird nests in semi-open, brushy areas, so could only be found where forest fires and other natural phenomena had created this habitat.
