Looks good for the faster trill of the Pine Warbler with the longer level trill, which is what I thought in the field
Gözlem detayları
WEWA would have shown a higher octave pitch, almost up to 9 kHz, but just as long , up to @ 2 seconds and OCWA would have been of shorter duration and with the pitch more varied. Doing a faster warbled trill from the trees around a ponded area in the forest over a long period of time. Have to check could have been a OCWA or WEWA or a BHCB maybe.
