The American Goldfinch or Spinus tristis/sad finch (when translated) is about 4.3 to 5.1 inches.During mating season male goldfinches has a bright yellow body, black wings with white stripes, a black cap on its head, and a white rump. Females and winter males have duller feathers that are an olive-yellow color. The male's black cap may disappear in the winter or turn a dull black. Females don't have the black cap on their heads. Both males and females have a small cone-shaped bill.
They mainly eat seeds, weeds, grass, and sometimes insects. They live in weedy fields and floodplains where weeds are abundant. They also could be found in cultivated Areas, roadsides, orchards and backyards. The American Goldfinch nest in open areas, and the nest itself is made up of rootlets, plant fibers, and lined with plant down. But mating finches do not actually nest until mid summer.
The Goldfinch's population has been stable and the only sign of a decrease in their population was during 1966 and 2014. Partners and flight had estimated their global breeding population of 42 million, 91% in some parts of the US, 33%in Canada, and 6% in Mexico during the winter.They are in low concern on Bird Watch.
