观察细节
Did not sing, but called. Call was not the sharp "Flik" of a Least. Head gray with slight peak, olive back. Distinct white wingbars. Some yellow on the flanks, but not on belly. White eye-ring. Probably Alder. The bird was moving around in shrubs and small trees on the banks of Lake Superior. Swallows and terns can be heard in the background on the audio recordings.
