[cobirds] American Goldfinch movements

Since late August our yard has been visited regularly by American goldfinches;  we usually see 1 male and  4 or 5 females.  They come to drink and bathe in the bird bath and feed on the
volunteer sunflowers in our garden.  We have not seen goldfinches here in many years (we live in central Denver) and wonder if dry conditions in outlying suburbs and fields are driving
them into town. We have also had a Wilson's warbler (female), a Townsend's warbler  and a couple of western wood peewees, not exactly our usual backyard birds. I would be particularly  interested in knowing if anyone has any observations of, or theories about, American goldfinch movements.
