Kommentarer
Calls recorded as murrelets circled above redwood canopy and then flew west towards ocean. Lots of campground noise in recording, as well as vehicular noise from nearby Pescadero Creek Road. Applied a pass filter at 200 Hz in attempt to reduce some of the vehicular noise. Also, user error at time point 23 seconds reflects knocking the pause button and then unpausing; actual elapsed time is 5-6 seconds.
Observasjonsdetaljer
approximately 30 minutes after sunset, one group of 4, plus another group of 3, called and briefly circled just above top of redwood canopy before flying out.
