Location........Burton Marsh, Cheshire, England, UK
1 'marsh tern', was noted early morning today, which I would have expected to be a Black Tern,.... but....it did appear to be showing much paler/whiter undersides, and was also much paler above, than I would have expected from a Black Tern.........is it too early/late for a White Winged Black Tern, to be passing through?
