Подробности наблюдения
Recording of sound and spectrogram attached. Typical Pacific-slope x Cordilleran intergrade. Not sure why this is flagged as rare while Cordilleran is not? In my experience intergrades likely make up over 90% of the "Western Flycatchers" in the area. Spectrogram of male position note is shaped more like that of Pacific-slope but frequency is closer to range for typical Cordilleran. Will try to record and analyze dawn song later.
