Yep, that's a moorhen, coot's first cousin. They are a little different eatingwise - coots are dark meat like ducks, moorhens are lighter like pheasants. These guys are very secretive and will flush on you like a grouse or pheasant. Coots will try to swim away first then flush by skittering on the water.
Either way, eat 'em up - but you MUST skin them and remove the fat. Unlike ducks, coot/moorhen skin & fat tastes AWFUL. Meat is like venison. Servie it medium-rare.
I love all of God's creatures, properly prepared.
