Setophaga pharetra
The Arrowhead Warbler (Setophaga pharetra) is a stunningly marked Neotropical migrant, belonging to the diverse genus Setophaga, known for its vibrant wood-warblers. Males are strikingly adorned with a prominent black arrowhead-shaped patch on an otherwise brilliant yellow throat and chest, contrasting sharply with their olive-green back, two crisp white wing bars, and a distinct black cap. Measuring approximately 12-14 cm (4.7-5.5 inches) in length and weighing 8-12 grams (0.28-0.42 ounces),...
This species primarily inhabits high-elevation montane coniferous and mixed deciduous-coniferous forests, often favoring areas with a dense understory near streams or forest clearings. It is typically found at elevations ranging from 1000 to 2500 meters during the breeding season.
Their diet consists predominantly of insects, including caterpillars, beetles, spiders, and flies, which they obtain through active gleaning and hawking. During winter and migration, they supplement their insectivorous diet with small berries and nectar.
Arrowhead Warblers are active, diurnal foragers, constantly gleaning insects from foliage or making short, acrobatic sallies to catch prey in mid-air, often high in the forest canopy but occasionally venturing lower. Males are highly territorial during the breeding season, defending their 1-2 hec...
The breeding range of the Arrowhead Warbler is primarily restricted to the high-elevation deciduous and mixed forests of the Appalachian Mountains, extending from northern Georgia northward through New England and into the Maritime Provinces of Canada. Key breeding strongholds include the Great S...
