Hi Carol, all-

Over the past decade +, America Robins have been spotted in all states
except Hawaii in all months of the year.  Rather than a strict north/south
movement, Turdus migratorius lives up to its scientific name (migratorius =
wandering) and tends to winter where there is abundant fruit or soft soil.
See https://www.allaboutbirds.org/is-it-unusual-to-see-
american-robins-in-the-middle-of-winter/. and Birds of North America
online, American Robin > Distribution, Migration and Habitat (
https://birdsna.org/Species-Account/bna/species/amerob/distribution)

I used the Line Graph feature of eBird to plot winter occurrence of
American Robin in Tompkins County starting in 2013. Although the Feb. data
for 2017 is obviously incomplete, we can see a definite trend of increased
frequency of AMRO's occurring on checklists over the past few seasons.
 2015 is the exception; and you may recall that was the only recent winter
of extreme cold temps and above average snowfall. Note the spike in mid-Feb
occurrence in 2014 and 2016, another trend that seems poised to continue
this year.  But this is a very condensed slice of data; winters that are
warmer with less snowfall will mean we see more robins.

separateYears&continue.x=16&continue.y=1&continue=Continue

Looking further back in eBird data, and/or looking at Tompkins County CBC
data could serve to illustrate more concrete trends for this region.
