Female American Goldfinches are a duller yellow than the male and do not have the black forehead. They can be olive green on top and brown in winter. They nest late in the season in mid-summer and usually produce 4-6 eggs. The female builds the nest so solidly that it can hold water at times. American Goldfinches are migratory birds and are often seen in large flocks.
