Burung kicau (Songbirds)
Golden-winged Warbler
Vermivora chrysoptera
- langka
- 35 km/h
- Hampir terancam
Golden wing patches, sharply declining. Hybridizes with Blue-winged Warbler, slowly losing its own identity.
- Populasi
- Declining; roughly 210,000 mature individuals globally, with about 70% of breeders concentrated in Wisconsin, Minnesota, and Manitoba
- Habitat
- Shrubby, early-successional habitat and regenerating forest edges/wet shrubby tangles for breeding; adjacent mature forest used for post-fledging; winters in premontane evergreen/open woodlands and shade-coffee plantations in Central America and northern South America
- Fakta menarik
- The Golden-winged Warbler has undergone one of the steepest declines of any North American songbird — roughly -63.8% range-wide over the past 40 years, with its Appalachian population down about 98% since the 1960s — driven by loss of early-successional shrub habitat and hybridization/competition with the closely related Blue-winged Warbler (the two are 99.97% genetically identical).
- Sebaran
- Breeds in the Upper Midwest/Great Lakes region (Wisconsin, Minnesota) and southeastern Canada (Manitoba, Ontario, Quebec), plus a small, sharply declining Appalachian population in the northeastern/eastern US; winters from Mexico and Central America south through northern South America
- Makanan
- Insectivorous — mainly caterpillars (especially leafrolling species) and other insects/spiders, gleaned from curled leaves and foliage using its slender, slightly downcurved bill
