Spent a few hours around Therfield. Not an awful lot to report. Most interesting sighting was of over one hundred Swallows, nearly all juveniles on migration, perched just above the ground in a recently cut field. They were obviously feeding on insects on or near the ground but made for quite a strange sight and something I’ve not seen before. A few Chalkhill Blues were out, mostly quite tatty.
Shepreth was overgrown and held little.
