Or do hummingbirds only appear to be busy?
Last evening, looking out the window into the side yard, I noticed a hummingbird stop to rest on a tree branch. Every few minutes she would go swooping over the house, presumably to visit the feeder on the back porch, and then return to the tree a minute later. What a life. Rest. Eat. Rest.

Another surprise was that I saw this same hummingbird swipe at a large insect. I thought hummingbirds only drank nectar! Come to find out, 50% of their diet is insects! So just putting out the feeders is nice, but the hummingbirds probably also like the flowers in my garden, since they attract more insects for them to munch on.
My husband asked another interesting question- do humming birds sleep? Yes, they actually can go into such a deep sleep-like state that sometimes people assume they are dead! The hummingbirds lower their metabolism at night by 95%, lowering their body temperature and conserving energy. They wake up automatically about an hour before dawn.
I'm going to take a look this week to see if I can spot a humming bird nest. Well I better bring along the binoculars. The nests are so tiny!
