Détails de l'observation
Singing and position note from same individual. Confirmed as intergrade by Andrew Rush at UC Berkeley, his thoughts: "The songs that you recorded are typical of intergrades. They appear more like Pacific-slope to me, but the peak frequencies are not as high and, e.g., the second song type in the typical sequence is more rounded. But, the second song type retains the break in the middle, which you really don’t find in pure Cordilleran populations. For pure Cordilleran, you are safest in southern Colorado and Utah and New Mexico, Arizona, and Texas. Otherwise, the populations tend to be at least partially intergrades (all the way to the Black Hills)."
