Is this a Clapper Rail?

[John Hawkins]

I was at Ding Darling today. Not much happening. But did find this. I think it may be a Clapper Rail. I have never seen one at Ding Darling. I used my Sony A700 with a Sigma 50-500mm lens. Data=500mm,1/250,f6.3,+2ev,ISO 800. Thanks for looking, John

Looks like a Clapper Rail to me John.

I think so. Salt water = Clapper, fresh water = King.
