Flycatcher looking bird calling repeatedly for over 20 minutes - closest distance 40 feet away perched on a snag 30 feet high. This bird responded to wwpw call by discontinuing calling for a few minutes and responded to eawp call (which sounded identical) by flying in to closest snag and increasing calling volume and rate.
