... and sheep can't believe their eyes! Conditions weren't great as we stopped at Foryd Bay and scanned the shoreline, but still there were birds. 72 Pale-bellied Brent Geese were joined by 26 Dark-bellied Brents. Clouds of waders swirled about: Golden Plover, Lapwing, Knot, Dunlin and Bar-tailed Godwits. Little Egrets fed in the shallow creeks. Next we moved on to nearby Dinas Dinlle where we again enjoyed watching the flocks of Golden Plover and Lapwing.With the strong winds and heavy showers, we decided to move inland a little way and headed for Parc Glynllifon. We wanted to check out the walks and cafe to go in the forthcoming new edition of Birds, Boots & Butties on the Lleyn Peninsula. A flock of Long-tailed Tits and Goldcrests passed through the Pine Trees, and Grey Wagtail fed on the damp path right in front of us. We followed the path beside the stream up the valley and had reached the furthest part of the grounds, when the movement of a washed-out grey warbler caught our eye. It was a Chiffchaff, but not a Chiffchaff as we know it. It was clean white below, pale grey-brown above, with just a hint of greenish wash on the tertials. The bill and legs were black and surprisingly, the tail was never pumped in typical Chiffchaff fashion. The bird appeared to be a Siberian Chiffchaff (Phylloscopus collybita tristis), a rare visitor to the UK. Sadly, the bird was too fast-moving to get a photo.Walking back to the car, we passed a flock of sheep. Don't know what Alan was doing as Ruth took the photo, but clearly the sheep had never seen anything quite like it before!
