Potential overwintering group first discovered by Tami R on 12/12. Small swifts, greyish-brownish overall, paler below with very pale throat, darker above with slightly paler rump, evenly tapered wings. See photos. Longer string of calls heard a few times (audio attached) - higher and thinner than chimney. Single note chip calls also heard, but I'm not yet sure whether they're audible on the recordings. See checklist notes for additional details
