Locations with breeding evidence of European Goldfinches in the western Great Lakes region. From records categorised as Probable or Confirmed, the highest breeding evidence is plotted in USGS 7.5-minute quadrangles. Black represents Confirmed, grey represents Probable, crosshatched represents European Goldfinch pairs (Probable) recorded in 2006 in quads where no records of multiple birds occurred in later years. Quads may contain multiple breeding locations and some quads overlap county lines. A confirmed breeding record in Ohio is outside the map boundaries and not shown (see Results).
