The last Hummingbird I saw at the feeder was on Thursday morning, September 15th. That morning it was only 21 degrees. After that the feeders have been quiet. I still have mine out however, as stragglers may still be coming through. It’s especially important now to have sugar water available for them as they would need the energy to continue on their trip. Some people leave them out until winter is truly here and even longer. Laura Erickson of Duluth had a rare hummingbird visit into December. Don’t worry about enticing a bird to stay longer because of your feeder – they know when it’s the time to go south.
