Whiteholme

Around midday huge numbers of Swifts were flying SW in a force 4 westerly.
I counted 300 in about 15 minutes, and the passage continued at the same pace when I stopped counting Swifts to focus on what else might be moving.

I logged 47 House Martins SW in 40 minutes. No Sand Martins however.

Other than these, just one Wheatear at Blackstone Edge.
