I am awed by the intelligence that flits through my back yard on a daily basis. I hang 2 ounces of sugar water from the awning in a tiny plastic tube, and a ruby-throated hummingbird finds it in a matter of hours. How does he do that? What sense leads him to this little tube in the midst of the vast world? Ditto for the chickadees who know when I’ve replenished the nyjer seed and the downy woodpeckers who drop in when the suet feeders are full. How do they know this? Do they instant message each other?
Here’s another mystery. I have lots of travelers, especially in the spring and fall.
