Lesser Goldfinch
Spinus psaltria
The Lesser Goldfinch is a diminutive and lively finch found across a wide range of the Americas. Often seen in small flocks, these birds are known for their acrobatic foraging and persistent, complex songs. Their bright yellow and black plumage, particularly in males, makes them a striking sight in open woodlands and weedy fields.

02 / A place in the world
Where life
takes it.
Lesser Goldfinches inhabit diverse semi-open areas, including open brushy country, woodlands, and wooded streams. They are also common in gardens, parks, agricultural lands, and weedy fields, often near water sources. They can be found from low valleys to high in mountains.
Stay a while. Or follow the season.
Most Lesser Goldfinch populations are considered resident, remaining in their regions year-round. However, they exhibit nomadism, particularly in search of seed-bearing plants, and may move from higher elevations during winter. Their range is expanding northward in parts of the U.S.
03 / Listen a little closer
A voice
of its own.
Their song is a complex and varied warbling, incorporating clear notes, wheezes, trills, and stutters. Males often mimic snippets of other birds' songs.
04 / The life behind the feathers
A day in its world.
On the menu.
Their diet primarily consists of seeds, especially from the daisy (composite) family, such as thistle and wild sunflower. They also consume seeds from various other weeds, tree buds, and some berries. Insects, particularly small ones like aphids, are eaten, especially in summer.
These finches often forage in flocks, sometimes mixed with other finch species. They are agile, balancing on tall plant stems and feeding upside down on seed heads. They also feed on tree buds and will visit feeders.
A place to begin.
The female builds a compact, open cup nest, typically in a vertical fork of twigs in a shrub or tree, often 1.5-9 meters above the ground. Nests are constructed from grass, plant fibers, and bark strips, then lined with soft materials like plant down or animal hair. They lay 3-6 pale blue-white eggs.
The little routines.
Lesser Goldfinches are social birds, frequently seen in small to large groups. Males engage in courtship flights, displaying their wings and tail while singing to attract a mate. They can be assertive at feeders, even chasing off larger birds.
