While I was keeping a close watch on the hawk nest ...
...wrens hatched out somewhere near my front porch.
I spotted One and Two (Three--obviously the problem child-- was on the other end of the porch) after they'd settled themselves in the rafters. Mom and Dad were hard-pressed to keep up with the demand for food, flying out and back, out and back. Eventually Three made his way to the group gathering with a series of four short flights to cover the approximately eight-foot distance.
While I still haven't found the nest, I'm so happy I got to see these youngsters before they headed out into the wild world.
