Detalles de la observación

First observed at 19:48 as soon as sun was down. At least five individuals simultaneously foraging overhead and seen from underside. Birds apparently attracted to exterior lights of structure; they flew back and forth through the light giving intermittent “peek” calls and a pair repeatedly churring. Incredibly active for about half hour, then no longer visible overhead. Site of recording was on a rise, with windy conditions heard on audio. No other birds observed.
