Hello, last weekend I was out walking in woods on the Welsh border when I heard a loud call overhead. I large bird of prey passed over. Half an hour later I saw the bird again, and the same noise. I get buzzards over the garden a few miles away so don't think it was that. And although there are red kites in a valley about five miles away, the tail did not look forked. Earlier today I was walking on farmland about a mile from last week's place when I heard the noise again and saw the bird. Has to be a bird of prey as it is pretty big. But the noise is almost like a duck or goose!? Like short series of honks is the best I can describe it. Is there a bird of prey that makes a non typical noise? Only other thing I can think is it is startling another bird. But seems coincidence. Any help much appreciated!
