A typical summer sight is a male American Goldfinch flying over a meadow, flashing golden in the sun, calling perchickory as it bounds up and down in flight. In winter, when males and females alike are colored in subtler brown, flocks of goldfinches congregate in weedy fields and at feeders, making musical and plaintive calls. In most regions this is a late nester, beginning to nest in mid-summer, perhaps to assure a peak supply of late-summer seeds for feeding its young.
