Detalles de la observación

This is just an estimate. When I got to this spot swifts were already entering the chimney. During the Swift Night Out the night before 329 were counted. Note: one swift tried to enter at the end and either it was rejected or there was no vacancy. It flew to the southwest hopefully finding another chimney. Started taking video towards the end.
