Yes. At night they come reliably to the hummingbird feeders. You can go to the overlook next to the gift shop and watch them there. Or, if you have a room with a back porch (as my brother's unit did but mine did not), you can borrow a feeder from the gift shop and hang it from a rod they have on your back porch. That is what we did. There are also a few different species of insectivorous bats, but of course they don't sip nectar from a feeder.
