This little bird is common and widespread. It’s nickname is the “wild canary” for its attractive, canary-like song and breeding coloration. It also has a song that sounds like a distinctive, sweet, twittering, “just-look-at-me” contact call, often heard from birds as they take to the wing with their dancing, strongly undulating flight.
The American Goldfinch is usually seen in pairs, family groups, and after breeding in large flocks.
These birds are late nesters, ensuring its young hatch in late summer and autumn when there are plenty of suitable soft weed seeds, such as those of thistles, sunflowers and teasels. The parents feed their nestlings on a regurgitated milkly pulp of seeds. The nest is so tight that in a heavy rain, if the adult bird is not sitting in the nest the babies would drown.
