About Lesser Goldfinches

These tiny finches are a common sight in the West and have unique chiming call notes. It is common to find yellow or green lesser Goldfinch flocks feeding in weedy fields or perched on cottonwood, scrubby oak, and willow areas.  Their twittering call notes often include short imitation calls of other birds. Some of their distinctive features include their color pattern, size, and behavior.

Description and Identification

Lesser Goldfinches are extremely small birds around 3.5 – 4.3 inches long with tiny stub-like
bills and short, notched tails. Their long, pointed wings span between 6 – 8 inches in length.
Like most other finches, this species exhibits sexual dimorphism through the colors of the
plumages of the sexes. Males have bright yellow underparts with glossy black upperparts,
and a large black tail marked with white corners. Their heads are completely black and can
extend to their backs or change into dull green in the cases of some populations along the
West Coast. Females and juveniles have olive-colored backs with dull yellow underparts
and black wings that are also marked by two whitish bars.

Lesser Goldfinch Color Pattern

Male Lesser Goldfinches have glossy black upperparts and yellow underparts. Their dark wings have white patches. Those that thrive on the West coast have dull green upper parts. The tail is usually black with white sides. The females and juveniles have olive upperparts and dull yellow underparts.

Lesser Goldfinch Size

They are fairly larger than an American goldfish but dwarfed by a song sparrow. They have short-notched tails, long but pointed wings.

The relative sizes of both sexes

  • Length range: 3.5-4.3 in (9-11 cm)
  • Weight: 0.3-0.4 oz (8-11.5 g)
  • Wingspan range: 5.9-7.9 in (15-20 cm)

Lesser Goldfinch Behavior

They forage in large flocks in shrubs, trees, and weeds. The flocks can often mix with other seed-eating birds. They forage individually during the breeding seasons. During courtship, the male performs several displays and feeds the female.

Lesser Goldfinch Food

Lesser Goldfinches mainly eat seeds from the sunflower family – such as napa thistle
(Asteraceae) – but also consume the fruits of coffeeberry, elderberry, and madrone fruits.
Buds of cottonwoods, alders, sycamores, willows, and oaks form an important part of their
diet as well. Their bills are useful in husking the seeds, as the birds generally do not
consume seeds whole. Like many other finches, they cling to the seed heads of tall plants
and hang upside down while picking at the seeds. Occasionally, especially during breeding
seasons, they may consume small insects like plant lice in order to consume sufficient

Lesser goldfinches feed mainly on seeds from sunflower. They also eat fruits of coffeeberry, madrone, and elderberry. They also feed on buds of oaks, willows, sycamores, and cottonwoods. In summer, they supplement their diet with insects especially aphids, and take salt.

Lesser Goldfinch Habitat

These birds are scattered across patchy open habitats from the western United States to South
America. They thrive in warm climates and can be found inhabiting thickets, weedy fields,
woodlands, forest clearings, scrublands, farmlands, and even desert oases. In urban areas,
they frequent gardens and parks in both suburban and central urban regions. Their habitats
in the western U. S. include oak, pinyon-juniper, cottonwood, willow, cedar, chaparral, and pine

Their habitat ranges from desert oases, woodlands, cleared forests, weedy fields, thickets, and scrublands. They are also a common sight in urban neighborhoods, parks and farmlands. In dry countries, they thrive in areas near water bodies.

Range and Migration

Lesser Goldfinches are another species of small, North American songbirds that form the
American goldfinches’ clade with American Goldfinches and Lawrence’s Goldfinches –
meaning that the three species all share a common ancestor on the continent. These birds
range from the south-western United States to Venezuela and Peru, with a majority of the
population being permanent residents of their habitats. Lesser Goldfinches at the northern
edge of their range – south-western and southern United States – do migrate southwards to
warmer regions during the winter, but their exact routes are still unclear to scientists.
However, migrating birds spend a majority of their winters along the Atlantic and Pacific
coasts of Mexico. The populations that range from California to Central America and
northern South America are permanent residents and do not migrate.

Lesser Goldfinch Lifecycle

The females lay 4-5 eggs and incubate them for 12 days. The hatchlings are fed by both parents and leave the nest after an unknown period. They produce 2-3 broods per year.

Lesser Goldfinch Nesting

Nesting sites are selected by the females along rivers typically in cottonwoods and willows
approximately 4 to 8 feet above the ground, though they can be found in multiple kinds of
trees and bushes. The nests are built by the females at a spot in a fork of branches that is
preferably concealed by vegetation for protection. As the females build the nests, the males
linger close-by to supervise and occasionally help. The outer cup is woven out of leaves,
bark, catkins, cocoons, and spiderwebs before being lined with hair, feathers, wool, rabbit
fur, or cottonseed fibers in the interiors. The resulting nests can host their clutch size of 3 – 6
eggs along with the incubating parent.
