Two swallows, noticeably smaller than tree swallows they were flying with. One tree swallow attacked one of the caves allowing us to see side by side. Buffy rump and throat, paler than a cliff would be. Flying over ferry landing toward the rocks. Seen by Jamie first, but we all had good looks, tried for photos but non turned out. Edit: adding poor photos (just after tree swallow attacked cave) to atleast show size and buffy rump.
