I leave my feeder up until frost. There are occasional late stragglers coming through.

Considering the question of when to stop feeding hummers, keep in mind that there are more hummingbirds than our Ruby-Throated. Hummers that are out of range can be out of season too. A quick visit to the archive of ARCC reports at the COA web site (ctbirding.org) turned these examples up, but there were more.
