Swifts

I notice a few reports of Swifts heading N in the last couple of days. I heard calls in Todmorden most of yesterday, and there were 6-8 birds feeding over the Stansfield area in the evening, so I assume this is our breeding population returning.
Also, belatedly, from Tod railway station on Saturday could be heard Chiffchaff and a drumming Great Spotted Woodpecker, amongst others.
