Himantopus himantopus – Hirgoes Adeinddu – Vagrant.
The Black-winged Stilt is a breeding summer visitor to mainland Europe from wintering grounds in Africa.
The Black-winged Stilt was first recorded in Pembrokeshire on the 24th July 1967, when G. T. McTaggart , a postman delivering mail, came across one on a small pond near Narberth.
The second was at West Dale, also visiting the Gann, between the 3rd and 6th April 1987.
On the 19th March 1990 a Black-winged Stilt was noticed wading in flood water at Penally by an alert observer travelling on a passing train, it remained until the 30th March.
Another was at Skokholm on the 7th and 8th May 1990, where it was frequently harassed by breeding Lapwings.

Black-winged Stilt head-bobbing
I had a long look at the Dale Black-winged Stilt on 6 April 1987 and was much impressed by the extent to which head bobbing was a prominent feature of its behaviour. The tempo of bobbing was neither fast or slow but it was rhythmic. It was accompanied by a somewhat bulbous inflation of the neck and a minimal flexing of the legs in time with the bobs. A bout of bobbing might continue for quite half a minute, the bird remaining silent- I was inclined to think that any movement by me, when I was already within 30 yards, would trigger off another bout of bobbing.
I have now checked through the literature on my shelves from Coward onwards. I find that only in BWP, Vol. lll, p .41, is this bobbing mentioned and that too is in the context of anxiety. Yet it is so obvious that others must have noticed it but nobody cites it as a specific characteristic.
