Golden-Winged Warbler – Profile | Facts | Habitat | Range

The male Golden-winged Warbler is a grey general with a yellow patch on the wing, black masks bordered by the white, black throat, and yellow crown; the feminine is analogous however much less strongly marked.

Golden-Winged Warbler profile

This species nests from southern Manitoba eastward throughout the northern tier of states and southern Ontario to New England, and southward within the Appalachians to northern Georgia; it winters from southern Mexico to Colombia.

Like the Blue-winged Warbler—a detailed relative with which it hybridizes the place their ranges meet—the Golden-winged is a trans-Gulf migrant, and therefore one of many rarest vagrant “eastern” warblers within the West.

Oregon has two accepted data, Idaho one, and British Columbia none. Washington’s single accepted document was netted and banded at Turnbull National Wildlife Refuge (Spokane County) on 20 August 1998.

Overview

A strikingly patterned warbler of leafy second growth and swamp edges. Once frequent within the northeast, it has been declining lately in the southern components of its breeding range.

As it disappears, its shut relative the Blue-winged Warbler has been advancing north. The Blue-wing could also be driving the Golden-wing out of the most effective habitats, however, the state of affairs will not be nicely understood.

The two species interbreed, creating distinctive hybrid varieties often called “Brewster’s” and “Lawrence’s” warblers.

Geographic Range

Golden-winged warbler, scientific name Vermivora chrysoptera is a Nearctic-Neotropical migrant present in eastern and north-central components of the United States and southern Canada.

These birds have been documented within the Great Lakes area of Michigan, Wisconsin, and Minnesota, the Cumberland Mountains in northeastern Tennessee, and the Appalachian Mountains in Kentucky, West Virginia, South Dakota, Pennsylvania, and New York.

These warblers are additionally discovered within the Canadian provinces of Ontario, Quebec, Saskatchewan, and Manitoba. During the winter, they migrate south into Mexico, northern South America, and the Caribbean.

Lifespan/Longevity

The lifespan of golden-winged warblers is poorly recorded. According to Klimkiewicz et al (1983), the utmost lifespan of a wild golden-winged warbler is 7 years and 11 months.

Golden-Winged Warbler Description

The frequent plumage of adult male golden-winged warblers is gray on the dorsal facet and white on the ventral facet of the body. Yellow will be discovered on the nape and in patches on the higher wing. Black feathers are prevalent down the wing.

Male and feminine wing chords are between 5.49 and 6.3cm. The wings include 9 primaries, 9 secondaries with three tertials, and 12 retries within the tail. Their tails are gray with white patches on the outer rectrices.

The bill of adult golden-winged warblers is black, however, it’s pink when they’re juveniles.

This is a small warbler, measuring 11.6 cm (4.6 in) long, weighing 8–10 g (0.28–0.35 oz), and having a wingspan range of 20 cm.

The male has a black throat, a black ear patch bordered in white, and a yellow crown and wing patch. Females seem just like males, with a light grey throat and light grey ear patches. In each sex, intensive white on the tail is conspicuous from under.

Underparts are grayish-white and the bill is long and slender. Unlike most warblers, juveniles will be reliably sexed (utilizing throat patch coloration) roughly 15 days after fledging.

They have a black bib and eye patch separated by a white line. Their eye coloration is black or darkish red-brown.

Their legs are darkish brown or gray as adults and darkish pink as juveniles, with pale green feet. Females differ from males as they have a gray bib and eye patches, with more distinctive yellow on the nape and the ventral facet.

Juveniles are darkish gray and blue, gaining the darker bib and eye patch at 18 to 19 days. The total size from head to tail averages 13 cm for adults. Adults weigh an average of 9 g.

During the spring and summer season months, the feathers of the body and the flight feathers molt and get changed with new ones.

Golden-Winged Warbler Behavior

Males have territorial encounters the place totally different shows and actions happen. This consists of crown elevating, tail spreading, chasing, and combating. Interspecific males shouldn’t have overlapping territories.

Males solely present defensive territorial shows when one other male has mated, one other male tries to make use of a taken territory, or when a male tries to get a feminine that’s already taken.

Intraspecific males have overlapping territories however keep away from one another.

Golden-winged warblers have overlapping territories with blue-winged warblers and hybridize as a consequence of their comparable plumage and song.

Another species generally seen with golden-winged warblers are black-capped chickadees.

Habitat

Open woodlands, brushy clearings, undergrowth. Breeds in brushy areas with patches of weeds, shrubs, and scattered bushes (akin to alder or pine).

This habitat kind is present in locations the place a cleared subject is rising as much as woods once more, in addition to in marshes and tamarack bogs. In winter, within the tropics, lives in forest edges and open woodland.

Diet

Mostly bugs. Diet will not be identified intimately, however feeds on many caterpillars and adult moths, particularly Tortricid moths, additionally different bugs and spiders.

Golden-Winged Warbler Communication

Golden-winged warblers have two sorts of songs, type I and type II. Type I is a two-syllable song with a high pitch “zee” adopted by Zero to six “bee” notes.

This song is more frequent and has little variation. Males sing kind I songs to draw a mate. This is the principle manner females acknowledge members of the identical species.

Type II songs are three to five syllables ending in a “buzz” be aware. Males use kind II songs when they’re aggressively interacting with different males, throughout flight shows, or early within the morning before dawn.

Males and females use the call tone “tzip” to draw the other sex throughout the breeding season.

Feeding Behavior

Forages largely within the higher level of bushes and shrubs in summer. Feeds by probing and choosing amongst foliage, typically hanging head downward.

Probes in curled leaves and pries them open in the hunt for bugs. May forage with Black-capped Chickadees on breeding territories and in-migration. On wintering ground, primarily feeds pretty low in bushes, in blended flocks with different species.

Golden-Winged Warbler Reproduction

Male golden-winged warblers arrive on the breeding grounds and choose a territory of about 1609 to 3219 m2 that primarily consists of overgrown fields. Females arrive a day or two later, they discover a mate that very same day and stay monogamous as soon as mating.

As quickly as females arrive, males are attracted by their “tzips” calls. Females take a soliciting posture, which is outlined by quivering wings, raised tails, erected crown feathers, and lowered breasts.

As quickly because the day after their arrival, females start constructing their nest on the tree line bordering the male’s territory. When a male approaches a feminine, the encounter will be aggressive or non-aggressive.

When the feminine responds aggressively to the male flying near her, she fights, snaps, or lunges on the male. Alternately, a non-aggressive feminine would give “tzips” calls after which depart.

Males follow two flight shows close to females together with moth and gliding flights. In a moth flight, the male flies slowly with marked wing beats and his head held high. Gliding can happen when the male is about to chase a feminine.

The breeding season of golden-winged warblers is as soon as a year from May to June, totaling six weeks. Within days to every week of arriving on the breeding grounds, the feminine builds the nest with leaves and bark, and when it’s full, she lays the eggs.

Eggs are incubated for 11 to 12 days, ranging from the final egg laid. The younger fledge in round 1 month and are sexually mature by 10 to 12 months.

The average clutch size is three to six, with a imply of 4.5 eggs. After the younger bird fledges, the parent could feed them for as much as a further 31 days.

Golden-Winged Warbler Eggs

5, typically 4-7. Pale cream or pink with streaks and blotches of brown and lilac. Incubation by female, 10-11 days. Up to 30% of nests have cowbird eggs.

Hatching of warbler eggs is low when cowbirds present, however, cowbird nestlings don’t essentially fare higher than the warbler nestlings.

Young: Leave nest after 8-9 days, are fed by parents for as much as one other month. Parents could divide fledglings into two teams, every parent attending solely a part of the brood. 1 brood per year.

Golden-Winged Warbler Nesting

Hybridizes with Blue-winged Warbler. Male arrives on territory in May, a couple of days before the females.

Male defends territory by singing; in aggressive encounters, he postures with raised crown feathers and unfold tail, and he could chase and combat with different males.

Males have two song varieties, one used to promote the territory and one largely for attracting a mate.

Courtship consists of male chasing feminine, elevating his crown feathers, sluggish wing beats as male flies away, and gliding flight as male flies towards the feminine.

Nest: Built by feminine on the ground at the base of a shrub or in a tussock of grass or sedge, often hidden by foliage. Open cup nest constructed of leaves, grapevine bark, and long strips of grass; lined with effective plant materials.
