birdwatching

A fat robin keeps flying around the tree outside, clumsily grabbing onto a slim branch for a moment, then flying around again. They've visited the empty nest a couple of times. I wonder if it's the same robin who was there before? Does she want to use the nest, or does she want to take it apart and rebuild elsewhere? Foliage and flowers are thick enough now that the nest is harder to see than ever.
