Habitat
Lesser Goldfinches feed in weedy fields, budding treetops, and the brush of open areas and edges. Depending on food availability, they may concentrate in mountain canyons and desert oases, but they are also fairly common in suburbs.
Ecology
These finches primarily eat seeds of plants in the sunflower family, and they occur all the way south to the Peruvian Andes.
