studying spectrogram - almost like a Pacific starts at or above 4kHz and ends just above 6kHz but discontious like Cordilleran. Note 12/04/2019: I'm updating records I have sonograms for or have studied the sonograms of from Pacific-slope/Cordilleran Flycatcher (Western Flycatcher)  to Pacific-slope x Cordilleran Flycatcher (hybrid).  I guess I feel we know that the birds in question are neither Pacific-slope or Cordilleran so the hybrid is a better match for these recorded birds in which the sonogram is intermediate between Pacific-slope and Cordilleran. Though maybe it should be listed as  Pacific-slope x Cordilleran Flycatcher (intergrade) ?
