"American Goldfinch," Wikipedia, the free encyclopedia.The American goldfinch begins its breeding season later in the year than any other finch and later than any other native North American bird, besides occasionally the sedge wren. This may be related to the abundance of seeds in the late summer months, as seeds represent the majority of their diet.American goldfinches lay four to six bluish-white eggs, which are oval in shape and about 16 mm 12 mm (0.63 in 0.47 in), roughly the size of a peanut. It is thought that they are laid during the night. The eggs are incubated by the female alone, though the male brings her food as she nests, and most mating pairs raise only one brood each year. The chicks hatch 1214 days after incubation begins.
