Observation details
NFC hundreds - passage started at 2012, last at 2201, peak passage around 2120, initially just male calls, then some (female?) 'squeaky gate' calls then lots of wing whirrs and calls of both (sexes?) but more whirrs than calls, constant at one one point suggesting very large flocks of hundreds/thousands.
