First visit ever here. At 12 noon 3 Black-tailed Godwits, increasing when we strolled back at 12.30 to 15 birds, having peered with some difficulty over to Lightshaw Hall Flash from the towpath in the meantime and seen perhaps 6 Black-tailed Godwits fly across a gap; so in all about 15/21 birds present, and likely more. Looks a great area.
