Hi David
I see those over the bottom of Newchurch Road and others on Haslingden Old Road near to the ski slope.
Not sure about Haslingden or Bacup.
I wouldn't say they were 'common' , the odd one or two over Seat Naze but I have no idea how far they travel.
Cheers
Ian
Swift numbers have been low over Waterfoot and Stacksteads this year. It was well into June before I saw any over Waterfoot. There are usually double figure flocks flying over Toll Bar in Stacksteads, but I've only seen up to 5 this year
