Yellow warbler

In downtown St John's, not very far from our house, there's a riverside path that also happens to be a good place to watch birds. We went there this afternoon to look for the newly arrived warblers and we weren't disappointed. There were matched M/F pairs of Yellow warblers and Black&white warblers, plus a dozen or so Yellow-rumped warblers. This was one of the Yellow warblers being frisky over our heads.
