Wild, female American goldfinch perched on a fence with the glint of the sun in her eye, Female Goldfinch. It frequently hangs from seedheads while feeding in order to reach the seeds more easily. [15] The sexual dimorphism displayed in plumage coloration is especially pronounced after the spring molt, when the bright color of the male's summer plumage is needed to attract a mate.[16]. It is thought that the inability of brown-headed cowbird chicks to survive is due to a failure to get enough nutrition; the seed-rich diet of American goldfinch chicks varies from the usual insect-rich diet of other hosts. Female American Goldfinch Perched on a Branch of a Tree, Closeup of American Goldfinch on yellow flowers,Ontario. It is migratory, ranging from mid-Alberta to North Carolina during the breeding season, and from just south of the Canada–United States border to Mexico during the winter. Frequently feeds in flocks at sunflower and nyjer seed feeders. [14] The beak is small, conical, and pink for most of the year, but turns bright orange with the spring molt in both sexes. [29] During the breeding season, this finch lives in loose colonies. [15] While the female incubates the eggs, she calls to her returning mate with a soft continuous teeteeteeteete sound. The nest-building lasts approximately six days, during which time the female works in 10–40 minute increments.

[5] Carduelis is derived from carduus, the Latin word for 'thistle'; the species name tristis is Latin for 'sorrowful'. Backyard birders attract it using feeders containing niger seed,[36] or by planting grasses and perennial plants, such as zinnias, cosmos, bee balm, or globe thistle, which produce seedheads favored by finches. Male and female pale of bright gold American Goldfinch songbirds. [6] There are four recognized subspecies of the American goldfinch:[7], This seems to be the most ancient extant species of the Meso-American Spinus/Carduelis evolutive radiation, whose parental species is Lawrence's goldfinch (Spinus lawrencei). Clearing of woodlands causes declines in numbers of neotropical migrants, while favoring short-distance migrants and permanent residents. American Goldfinch female perched on thistle feeder in Arlington Heights Illinois 604241 Carduelis tristis, American Goldfinch female. Get Instant ID help for 650+ North American birds. In winter, in the northern part of its range, the finch may move nearer to feeders if they are available. For up to three weeks after fledging, they are still fed by the male, who locates them by listening for their fledging call. [22] This habitat preference continues during the spring and autumn migrations. [30], The American goldfinch indicates its degree of aggression through multiple displays. [1][7] The clearing of forests by humans, though harmful to many species, has benefited the American goldfinch. At Jensen Lake - Lebanon Hills Regional Park, American Goldfinch Carduelis tristus Female. [28], The courtship rituals of the American goldfinch include aerial maneuvers and singing by males, who begin courtship in late July. The autumn plumage is almost identical in both sexes, but the male has yellow shoulder patches. In extreme cases, the neck is retracted, the bill opened, the body feathers sleeked, and the tail is fanned and raised slightly. [16] There are two defense calls made by adults during nesting; a sweet call made to rally other goldfinches to the nest and distract predators, and a bearbee used to signal to the nestlings to quiet them and get them to crouch down in the nest to become less conspicuous. Perched on a bird feeder eating seeds. An American Goldfinch, and a male and female House Finch perched on a bird, Yellow American Goldfinch bird at the feeder in the backyard. Female American Goldfinch feeding on a thistle, American Goldfinch Perched on a Slender Tree Branch. Avoidance behaviors include showing only the side of the body to an aggressor, leaning away, flexing the legs, retracting the neck, and pointing the beak down. [28] The social hierarchy in the breeding season generally has the female dominant over the male. At higher intensities, the neck is lowered, the beak is pointed at the opponent, and one or both wings are raised. [36], The American goldfinch is not threatened by human activity, and is widespread throughout its range. Despite having a fairly small bill for a finch, goldfinches can crack and remove the hard shells of sunflowers, then crush the seed inside before swallowing. This aggressiveness subsides once the eggs have been laid. Side profile, Female American Goldfinch perched on pine sapling, Walton County, Georgia USA birding photography. On plum tree branch, American Goldfinch Spinus Tristis female. Spring males are brilliant yellow and shiny black with a bit of white. For much of the year, distinguishing male and female American Goldfinches is easy (when the males show their brilliant yellow summer plumage, about March through September). [34] The American goldfinch also makes a very poor host for brood parasites, with studies showing low hatching rates of brown-headed cowbird eggs and no fledging success. While the nest is being constructed, the male will act aggressively toward other males who intrude into his territory, driving them away, and the female reacts in the same way toward other females. [29] Dominance may change based on the value of a resource; a study published in 1987 found that starved subordinate birds were sometimes dominant in competitions over feeder access. [24] The eggs are incubated by the female alone, though the male brings her food as she nests, and most mating pairs raise only one brood each year. According to the Cornell Lab of Ornithology, the species is one of the strictest vegetarians in the bird world.
