American Goldfinch — size comparison — facts and sources
The American goldfinch feeds primarily on seeds. It visits thistles, sunflowers and other herbaceous plants, and small flocks may settle on their seed heads.
It breeds later than many other North American songbirds. Breeding timing is linked to the maturation of plants supplying both food and nesting material. It lines its cup nest with fine fibres, and the young receive a diet based mainly on plant food.
Outside breeding it can be highly sociable, moving between productive feeding places. Its presence at a particular site may change with seed availability.
