Canada Warbler
Cardellina canadensis
- epik
- 72 km/h
- Risiko rendah
Yellow chest, black necklace, and a hurry to be elsewhere. Spends barely two months on its breeding grounds.
- Populasi
- ~2.6 million mature individuals, population trend decreasing (large, significant decline averaging ~2.2%/year from 1970–2017, with the rate slowing to ~3% decline over the most recent decade). Estimates range from ~1.5 million to ~4 million individuals.
- Habitat
- Breeds in moist, shrubby-understory habitats — mixed conifer-deciduous forest with mossy/fern understory, riparian thickets, brushy ravines, forested wetlands/bogs, and (regionally) montane rhododendron thickets or aspen stands; winters in mid- to upper-elevation tropical/subtropical forest edge and thickets along the Andes.
- Fakta menarik
- Nicknamed the "necklaced warbler" for the bold black streaking across its yellow breast; despite being designated a "Common Bird in Steep Decline," its still-large range and population keep it assessed as Least Concern.
- Sebaran
- Breeds across Canada (southeastern Yukon to Nova Scotia; roughly 82% of the breeding population) and the northeastern United States south through the Appalachians; winters in northern South America along the Andes from Venezuela/Guyana south to Ecuador, Peru, and northwestern Bolivia. One of the longest-distance migrant wood-warblers (>3,000 miles each way), among the last to arrive on breeding grounds each spring and first to depart in fall.
- Makanan
- Primarily insects and other arthropods — beetles, flies, mosquitoes, moths, and smooth caterpillars (e.g., cankerworms) — plus spiders, snails, and worms, with some fruit taken seasonally. Forages actively low in dense understory by gleaning foliage, and often flycatches for flying insects.
