Hummingbird behavior

I had a female ruby-throated hummingbird perched on a window feeder (she looked fluffy like maybe a young one). She perched for a very long time and had her eyes closed. My husband removed the feeder from the window and she stayed perfectly perched, but still seemed to be sleeping. It was a little cool outside (around 60). I cupped my hands around her and tried to warm her. She would occasionally wake up and I could get her to take drinks of sugar water out of a pop bottle cap. She eventually flew (very slow) into a tree where she seemed to stay. I don't know what was wrong with her or what I should've done.

Birding Expert - George H. Harrison

There was nothing wrong with the juvenile ruby-throated hummingbird. When the temperature cools, hummingbirds will often put themselves in a state of "torpor," a kind of sleep, to slow their metabolism and conserve energy. They sometimes hang down by their feet from feeder perches. This is a normal behavior, and nothing about which you need to do nor to be concerned.
