This pack is probably the best thing you could buy if you are going to Great Britain or Ireland and have anything remotely resembling a casual interest in birds. The map shows a good bird spot easily within reach from almost anywhere (need your own road map or GPS) and the book has every bird that breeds or winters in in the region, as well as some of the more common rarities. The regular birds get whole pages to themselves, rarities are several to a page. There are also page illustrations of problem groups, and Bill Oddie's writing is superb, almost as though he is there with you giving you help. The only thing missing is the plane ticket!
