Two weeks ago, I was birding on the Mohawk-Hudson Bike Path in Upstate New York, Schenectady County, when I heard something strange, like some creature slapping the water. I started sneakily coming toward the bush where the sound seemed to be coming from until I saw a branch that was vibrating. Peering into the brush with my binoculars, I spotted a tiny bird, sparrow size or smaller, moving the branch somehow. It was very hard to see through the thick brush. Could it have been feeding on insects? A few minutes later I saw another one. My birding companion said I looked like I wanted to become one with the bush. I would have stayed longer, but we had other birds to see.
