Unfortunately the island is closed to the public until May 1st but I was
very lucky to get invited to the island yesterday.
There was a small flock of European Goldfinch in Hammock Grove of ~12 birds
and a small group of 5 (same birds?) seen off Nolan Park later in the day.
I was looking into European Goldfinch sightings on eBird and the most
recent one in the area is from Prospect Park on Nov 26th of one bird. The
only sightings "locally" are from Bermuda and points north of Chicago. The
number of individuals from the Lake Michigan group are no higher than 8
individuals for sightings between Nov-Dec of this year.

... zoom out to view sightings from Bermuda.
Is the most likely explanation that these are a new set of escaped birds?
Or could the weather have had an effect on local populations? They
understood Sweetgums as a food source and the birds were very vocal. How
quickly do newly escaped birds take to Sweetgum Trees?
