This afternoon, at around 4:25, I located a Palm Warbler near where the bridge crosses the stream in Dutch Creek Park in Louisville CO. The bird was foraging at a very low level, often on the mud along the stream, and kept returning to the bridge during the course of my observation period(40 minutes). Active warbler, pumping tail often, with a rufous crown, bright yellow throat extending down to center of belly, brown streaking on sides, brown face, and a brown back. eBird link:
