I was present when this bird was around (we spoke).
Can you post any clear pictures if you get them. There's still some debate down here in Winchester as to its identity.
Apologies for the delay. I'm the photographer who was next to you. I've got some photos but they're not brilliant. Email me at collinsphil@hotmail.com and I'll send them to you.
Hi, folks. Good to see all the photos. One clearly shows a bird with a bill that's too long for a SC. I saw the juv W Rail there a few days after and it certainly looks like this bird.
Cheers,
Andy.
I think we can conclude that this was indeed a Water Rail. Some very experienced birders above have ID'd it as such (including seeing the bird themselves), which is certainly good enough for me.
Nice that the bird generated a decent debate though.
