觀察細節

Many birds heard but not seen. I am not yet proficient enough to identify most birds by sound alone. There is much interference from bugs, wind, footsteps, and the dog breathing, so the camera did not record many of the high pitched or distant sounds well. NOTE: The "mrrr" sound at 0:35 seconds in one of the recordings is my attempt to reproduce a sound heard directly before starting the recording.
