There are still lots of hummingbirds around. Our hummingbird feeder is getting constant use as the birds fuel up for migration. I went away last weekend and filled the feeders before I left. When I returned, one was empty and the other was half full. Hummingbirds frequented the feeders all summer, but their consumption has definitely gone up in the last two weeks. So, if you have activity at your feeder, keep an eye on the level of the liquid.
