I was intrigued by the discussion of whether in recent years
more robins are being seen during winter in the Twin Cities(Charles Neil, Mary
White and J. Baumann). I think that I
have seen more robins, particularly in large flocks, in
recent years. To put this hypothesis to the test I looked at the
Buckthorn!

It would be interesting to compare the data of outstate CBCs as well.
I haven't lived in Minneapolis during winter since 1997, and it seemed
noteworthy to me to see large numbers of robins in the winter. A few
years ago I visited Minnehaha Falls around Christmas and couldn't
believe how many there
I just heard this evening that Robins eat Buckthorn berries. Of course, we are
trying to eradicate that invasive. I hope that isn’t causing less food for the
robins.

While the availability of fruit is important, a more limiting factor in
numbers of robins in winter is the availability of liquid water. I believe
that in recent years the warmer winters have resulted in more availability
of liquid water, which should have increased the area where robins can
thrive

There could well be multiple factors. I will just add that the "distinct
inflection point around 1996" noted by Val Landwehr happened at about the time
