Hag Lane and Shibden Valley

An hour up there mid afternoon.
An amazing number of House Martins feeding in the shelter of the valley, mostly in the area north and south of Shibden Mill Inn. Also lots of Swallows though these were feeding at a higher elevation. Impossible to count but maybe 100+ Hs M and 50+ Swallows (??)
Also a few Jays around and about and starting to show now that the acorns are ripening.
