Displaced Sand Martins

Hi David,
Since the movement of Swifts on 23rd June 234 in an hour West at Thornton, Sand Martins have been in evidence on all our reservoirs, 50+ at Silsden Res on 29th June, 60+ feeding over Leeshaw res on the 5th July, also a male Whinchat at Leeshaw on Monday the 2nd of July Moving through.

Brian Vickers.

Anyone else getting displaced Sand Martins?
