Tweets, I once heard a ?typical? MacGillivray?s song from a grassy slope barely outside a moist meadow/pasture. Thinking this a strange location, I gave chase and discovered a C. Yellowthroat. I did not notice any unusual plumage pattern.

The weird warbler we reported last Sunday at Duvall was most likely a
MacGillivray?s Warbler x Common Yellowthroat hybrid. Steve Mlodinow reports
that this hybrid has been described previously and that some had the white
throat we observed. Dennis Paulson thinks it could have been that the female
was MacGillivrays, the male the Yellowthroat, which might help account for
the otherwise puzzling white throat. The song (which I was not able to
record) could conceivably have been described as intermediate between the
songs of these two species, though if it learned its song from nearby
songsters it?s a puzzle what species those might have been. If anyone is in
the area and would like to try to relocate it, the GPS coordinates are N
47.73347, W 121.98959.
