Drake Common Scoter as reported by DJS still on Mixenden reservoir today at approx 1205 hrs. It looks like staying today due to the rain and slight mist which didn't inspire any attempts at photography especially as the bird kept itself at distance at all times.
The same conditions gave rise to low flying Swifts at head height allowing very good views with the naked eye. Also several House Martin few Swallows & 2 Pied Wagtail, 6 Canada, c8 Mallard.
Thanks to DP for the journey and Dave for the alert.
