Their late mating season is due to the food source they prefer to give their young. This is the time weed seeds and thistle begin to ripen. Male is a small canary-yellow bird with black wings, tail, forehead and white wing bars. Female is a dull olive-yellow with blackish wings and conspicuous wing bars. Goldfinches are found in weedy fields, orchards, open second growth woodlands, roadsides, especially in patches of thistles and sunflowers.
Goldfinches feed predominantly on weed seeds and insects when available.
