The recording of the water rail in opus only gives the pigsqueal grunt, which if it was the only thing you heard would hardly equip you for the other sounds the bird makes. I agree there is a superficial similarity between the pattern of some of the Water rail's call and the Corn bunting, but the speed is different, the pitch is different.Bird calls vary between individuals and location, with regional variation, urban Blue tits for instance have a higher pitch call than their country cousins, to cut through traffic noise.All you can do is get out there, look and listen.Just for information: the first 40 seconds of the water rail recording are of an advertising male, the second 13 seconds (the corn bunting soundalike) are the courtship song of a female.Information and recordings taken from "British bird sounds on CD" from the National Sound Archive, published by The British Library.
