    Equipment Note

NOTES: This bird did quite a bit of mimicry, including Carduelis sp. call notes at the beginning of its song. This call notes were usually the signal that it was about to start its flight display. At 19:00, I switch to using a 160Hz high-pass filter on the Sound Devices 744T. At 22:00, I switch to using a 80Hz high-pass filter on the Sound Devices 744T. I switch off all filters at 32:40.
