Put that way, both sounds are there and can be separated.
The higher sound is perceptually hid by the way people hear but both
are there. If you did get to record the Bobolink up on the hillsides
on Sat PM then take a look at the graphic display of that call and
you will see two similar volume but independent melodies sung at the
same time with different pitches. Separation of them is a real chore
though. And we could go into a long discussion regarding phase
cancellation but it is not that big of deal on different pitches in a
quiet environment.
