It's still somewhat of a mystery to me. I'd be inclined to agree with the
gentleman who called it a Bewick's Wren. They normally don't like to get
high up in trees unless they're well concealed, but your hawthorn & holly
are obviously thick enough for that (since you didn't see the bird). And
calling it a Bewick's Wren is a great cover for my ignorance, since they
do make a startling variety of calls ("the bane of Western birders" is what
one friend has called them). Be sure to listen to several different tapes to
get an idea about this variety.
