Study Golden-winged Warblers?
The Golden-winged Warbler is declining precipitously in the northeastern U.S. (7.6% per year in USFWS Region 5), while increasing in the northern and northwestern portions of its range where farmland abandonment and clear cutting is common. The decline may be due, in part, to a loss of shrubland habitat. In addition, this decline correlates with the range expansion of the Blue-winged Warbler into the range of the Golden-winged Warbler. The northward expansion and resultant zone of overlap has led not only to increased competition, but also to widespread interbreeding between the Golden-winged and Blue-winged warblers. Because of this wide-spread hybridization, populations of pure Golden-winged Warblers may soon disappear after the arrival of the Blue-wings. Thus, the atlases produced through GOWAP will address two management needs that relate to the currently changing range of the Golden-winged Warbler and interactions with the Blue-winged Warbler.
