It wasn't until afternoon that I took my daily walk to the river. As I approached the bridge I saw a lively little warbler that seemed to be jumping for joy at the fineness of the day. It was busily moving about; darting here and there. When I got closer, it turned as if to introduce itself, and displayed its yellow rump giving me immediate recognition of a Yellow-rumped Warbler. It seemed to delight in its movements and was flying about from one side of the bridge railing to the other. It would find a new location to perch upon and then be gone again as quickly as it had arrived.
