I liked hunting the odd moorhen last season, on more open land I suppose they can be caught easily but I know a patch of bramble around a large pond where it took time to locate and flush them. We had a few good hunts with the hawk crashing through cover , most of the ones I put up for her made it safely across the water into more cover but a few went the other way into the field and then it was a forgone conclusion they would be caught.
I found the hunts were quite exciting. I imagine like all quarry everything rests on the terrain, rabbits are easy if bolted from the middle of big open fiel
