English: :Agitated song from a bird perched about 20m up in a leafless Red Oak. For the first minute, it sang its normal simple trill. Starting around 0:53, it began to sing in a very jumbled, agitated manner. I suspect this was triggered by my presence. Toward the end of the recording, the bird settles back into a simple trill, and at the very end, it flies off chasing another junco while calling. All vocalizations from a single bird.
High-pass filter @ 2kHz. Still a fair amount of noise from traffic, airplanes and wind.
