A question about how Eurasian Goldfinch might fit into our ecosystem if it
expands its presence in North America. I have seen them in Europe in several
countries but don’t recall if they were generally in the types habitats where
American Goldfinches nest. Visiting an aunt and cousins in suburban Pittsburg
the past two summers, I was surprised by how the American Goldfinches there
were in habitats with large trees, though not dense forests, while ours are
mainly in brushy edges to grassy open places, or emergent low brush and trees
during nesting season. In my experience, in winter they often are in large seed
producing trees in Portland, but never nest in such areas. My impression of
the eastern American Goldfinches is that they use the habitat in summer that I
think is typical of Lesser Goldfinches in the Portland area. Maybe they also
use habitats in summer similar what they use in Oregon, but the Pittsburg area
has little of such habitat. I never considered the matter when I have seen
Eurasian Goldfinches in Europe. Does anyone have an opinion about this?

The presence of European Goldfinches in Wisconsin led me to look at the eBird
map for the species. https://ebird.org/species/eurgol ;

There is a concentration of the species in northern Illinois and Wisconsin,
plus Detroit and New York, with scattered sightings from Virginia to New
Hampshire. One possible sighting west of the Mississippi south of St. Louis,
and many in California, especially the Bay Area.
