The usual Jumbo rubric: as the solution is available alongside (or indeed before) the blog, comment is confined only to references that might remain obscure to overseas / inexperienced solvers even with the answer visible, or anything I thought notably good or deserving a question mark; other clues are, however, happily discussed by request, please comment if required.
A slightly on the hard side of average puzzle, I thought, in terms of both wordplay and required GK.

| 15 | TWITCHER – see here for an explanation of the distinctions between twitchers, birders et al. |
