But I'm not interested in Kingfishers anyway .... I'd be interested to hear the response from someone who is, eg Blythman, who takes great natural looking bird photos. Does he feel the same as me, or is he wowed and inspired to get those lights out and set up down by the lake .... ?

Never fear !.... I don't know if this is exactly what happened with this image David, but what I think the guys are saying is that there were two 'effective' exposures, one after the other....
The first was the ambient exposure of 1/15thsec, and this recorded the blurred movement ....
The 2nd was the flash exposure of an extremely short duration. (eg 1/15,000th sec), and it was this that recorded he sharp 'frozen' parts ....
The '2nd (or trailing) curtain sync' thing means that the ambient exposure records first and then the flash exposure occurs at the extreme end of the ambient exposure. This ensures that the blurring appears at the 'trailing' (rear) end of the moving object, a natural looking phenomenem.
But. .... The effect is usually seen on the whole subject, as a blurring of the whole subject with a frozen outline, do I agree with David that in this image it appears odd .... Or at least the flash technique I've just described cannot explain everything about the image.

rear sync flash!

That blue streak behind the kingfisher can't be for real, the bird is pin sharp (1/15th sec)? really? If the bird was frozen by flash how come there is a trail at all?
I'm not knocking the excellent photo, all the above organisations would praise this image in an open competition, but in natural history?
I'd be interested to know a lot more about how this picture was achieved.

The question is really over whether the standard flash technique we're talking about, rear curtain sync with a fairly long exposure, could possibly have produced this image alone. In flash-speak the technique is known as 'dragging the shutter', with the long ambient exposure recording the blurred movement and the flash burst right at the end freezing the subject outline. The 2nd curtain sync mode ensures that this outline is positioned in front of the blurred elements, which therefore 'trail' the subject.
But of course the whole bird was moving, not just the tail, so I do not understand why the blurring is only seen on the tail, unless it is a blend of different frames.
