Hi again Jamie,
Thanks for posting the photo. I've tried zooming in but can't distinguish the detail.
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.
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.
Agreed. A good debate. I'm going to assume the matter now closed. Thanks for your help.
