don't laugh "yankee," in upstate ny in winter, you could get a rufous hummingbird in your yard
they migrate west to east, not north to south, and i believe new york state gets a couple a year
here in louisiana, we get many species and many individuals of "winter" west to east migrants, but i would not give up even in new york
hummingbirds migrate based on day length not on whether or not you put up a feeder, there isn't actually any harm done by leaving your feeder up all autumn and you increase the chance of getting a rufous, but this was the old theory from decades gone by when it wasn't known that many hummingbirds can and do migrate west/east rather than north/south
almost no northerner knows this, they are all shocked and charmed to get a winter hummingbird, i envy your future discoveries
on the gulf coast we have the benefit of many fine hummingbird researchers allowing us to band/track many different individuals of i think 9 different western species over the last 20 years
