Purple Sandpiper at Farmoor |
I braved the winds on Saturday and went out walking on Port Meadow in the hope of some storm-driven seabird. No such luck, but there were quite a lot of gulls lingering over the floods - usually they disperse during the day but I assume they must have been grounded. The individual below caught my eye and I'm still puzzling a bit over its identity. When I initially saw it fly past through bins I assumed it was a Caspian Gull (largely due to the white underwing and general structure), but it has a tail pattern that is much more typical of Yellow-legged Gull (in fact, out of hundreds of Caspian Gulls I don't think I've ever seen one with a tail like this) and very dark wing feathers with reduced inner primary window. To me the face/eye position and head shape are a bit weird as well.
After getting a few opinions it seems that my initial impression was correct and that it's most likely to be a Caspian Gull (presumably a large male). Usually I find that most individuals are fairly easy to assign to either Caspian Gull or Yellow-legged Gull (a much trickier problem is the separation of some Yellow-legged Gulls and Lesser Black-backed Gulls) so always good to come across an instructive bird like this.
