It was certainly an older bird, and a Male. We have a family breeding
(they're making the nest now) just down the road, and they're the only
magpies I see in the, well, valley I live in. So I can only assume that the
bird that was calling was the Adult Male that we see here, maybe he was
fending off an intruder ;)
