Observation details
Group of about 4 seen first at 11:35 from staging area overlook; then much better and extended looks from overlook at the start of the boardwalk; at one point I saw 6 swifts at one time, but mostly they were in groups of 3 or less; they flew along the south cliffs, sometimes flying overhead or ranging out, at other times dropping below the cliff top; occasionally calling when a pair interacted; one bird in juvenile plumage with white streaking on belly--I believe this likely indicates successful breeding in this area; see photos.
