Big fall of Chiffchaffs and Small Eggar visit

Small Eggar

Chiffchaff

I don't know why but for some reason my predictions are often on the day before the fall and this happened again on this occasion. The troughs developing off the south-east coast of Spain did become a series of fronts and did move north into the UK but not until later on the day of prediction and this I think is why my predictions are sometimes out by a day. Last nights temperatures were held up by the warm air dragged up from the south, humidity levels rose from 40% to 55% with just a light spell of rain at mid-night. Winds stayed light and variable until just before mid-night when they picked up to light northerly. Later in the early hours of the morning the winds swung to easterly and then south-easterly by dawn. This morning it was evident that there had been an arrival of Chiffchaffs. I made my way to Brean and could see Chiffchaffs in good numbers on the Down in excess of 30 birds.
On the moth front Small Eggar and Agonopterix alstromeriana in the garden trap were the highlights and an hours trapping on Brean produced: 2 Red Chestnut, Dotted Border, Early Grey, Mottled Grey, Twin-spotted Quaker, Hebrew Character, Common Quaker, Shoulder-stripe and March Moth.
