KEEP THOSE FEEDERS UP!! Make no mistake, these western hummers are very cold hardy. Several years ago I banded a November Rufous Hummer in Lemont that, on her last day seen the following January, it was -9 F. with a wind chill of -30 -35 F.
This bird currently holds the low temperature tolerance record for a Rufous Hummingbird!
Just a reminder that now that it is November, if you observe a hummingbird at your feeders please contact one of us and we will make arrangements with you to come out to catch, band and identify it. Yesterday I was in NE PA and although one would not go in the trap, I did manage to catch two rufous hummingbirds that were only 1.5 miles apart. Today, I was able to catch and identify another rufous in southeast PA.
