Cordilleran Flycatcher


At the Cayuse Bridge over the Umatilla River near Pendleton, 6/22/14. This bird was high up in a tree, but could be viewed at eye level from the bridge:


A 2-second video clip where the bird gives its male position note:


Spectrogram taken from the 2-second clip, which shows the distinct two notes (vs. the one-syllabled Pacific-slope Flycatcher position note):


Background information:
"Male position note: Most birders use only one clue to identify these two species (Pacific-slope vs. Cordilleran Flycatcher): the subtle but distinct difference in the position notes of the males. Pacific-slope gives a one-syllabled upslurred whistle, and Cordilleran gives a two-syllabled up slurred whistle"
