Media notes
A jet is approaching near the end of the audio unfortunately, but the Swifts were quite low over the trail allowing for a somewhat decent audio!
Observation details
Flying quite low over the mid-point of Harkins Ridge Trail as I ascended, it was amazing to hear them calling regularly as well! I actually managed to get an audio of it (attached). Tough to get an accurate count but 16 is real close I think.
