As unlikely as this sounds I'm pretty sure that I saw a pair (male & female) of Golden Oriole this morning below Stanage Edge near Hathersage in Debyshire. The male caught my eye first: bright yellow, bigger than a blackbird, smaller than a wood pigeon, undulating flight, flew out of a tree. It just went out of sight when I saw a duller bird having the same size and shape and squared off tail, which I took to be the female, fly off in the same direction as the male.
The RSPB website would suggest this is a highly unlikely sighting (too far north) but I can't think what else it might be. The only other birds I can think off that are this yellow would be Yellowhammer and Yellow Wagtail and it was much bigger than either of them. Nor was it a Green Woodpecker, though it was that sort of size.
Anyone got any other suggestions as to what this might have been if it wasn't an Oriole?
