Recorded by Benjamin Van Doren. Approximately 30 birds circling overhead, occasionally chasing each other. At first, heard vocalizing multiple times overhead around 8:02 AM but remained unseen. Very rapid calls, often equated to laser fire. 'Wop-wop-wee-bow-bow.' Unlike the constant twittering of Short-tailed Swift (Tumbes). Later refound at 8:45 AM higher up the trail. A good sized, fairly tight flock kettling somewhat low above the treeline. Interestingly doing a lot of gliding, fanning out their tails in the process.

*very rare/unexpected* First record for Jorupe lodge, I think. I can only think of one other record for the SW off the top of my head. Number is a rough estimate, but there could have easily been more. At first, heard vocalizing multiple times overhead around 8:02 AM but remained unseen. Very rapid calls, often equated to laser fire. 'Wop-wop-wee-bow-bow.' Unlike the constant twittering of Short-tailed Swift (Tumbes). Later refound at 8:45 AM higher up the trail. A good sized, fairly tight flock kettling somewhat low above the treeline. Interestingly doing a lot of gliding, fanning out their tails in the process. BVD has an iPhone recording of the calls, GM has photos. We recently acquired familiarity with this species the week before in the NW. DEFINITELY an overlooked species!
