Lesser Goldfinch
Lesser Goldfinch
Spinus psaltria
At a Glance
Very common in parts of the West, this tiny finch is easy to overlook until one learns its chiming and twittering callnotes. Small flocks of Lesser Goldfinches are often found feeding in weedy fields or in streamside trees. Two color patterns occur in the United States, and males in some areas may be either green-backed or black-backed. The complicated song of the male usually includes short imitations of the voices of other birds.

Behavior
Eggs
4-5, sometimes 3-6. Pale blue to pale blue-green, usually unmarked. Incubation is by female only, about 12 days. Male may feed female during incubation.
Young
Both parents feed the nestlings. Age at which young leave nest is not well known. 2 broods per year, perhaps sometimes 3.
Feeding Behavior
Forages actively and acrobatically in trees, shrubs, and weeds. Except when nesting, usually forages in flocks.
Diet
Mostly seeds, some insects. Majority of diet at all seasons consists of seeds. Especially favors those of the daisy (composite) family, such as thistle and wild sunflower, also seeds of various weeds. Also feeds on flowers and buds of trees (such as cottonwoods) and on some berries. Eats some insects, especially in summer, mainly small ones such as aphids. Will feed on salt.
Nesting
In warmer parts of Southwest, breeding season may extend over much of year from early spring to mid-autumn. In courtship, male feeds female; performs display flight with wings and tail spread widely, fluttering rapidly while singing. Nest: Usually placed in vertical fork of twigs in shrub or tree, 5-30' above the ground, sometimes higher in tree or very low in bushes or dense weeds. Nest (built mostly or entirely by female) is a compact open cup woven of grass, plant fibers, strips of bark, lined with plant down.
Conservation
Conservation Status
Widespread (including much of tropics) and fairly common, numbers probably stable.
