Just to confirm that on 11th September 2009, there was a steady flow of hirundines, principally Swallows, moving south through Wharfedale throughout the afternoon period - 11.30 hrs till 16.30 hrs. Birds were generally high and passing in flocks of up to circa 50. Difficult to estimate numbers, but would say around the 800 - 1000mark.
Cheers
