The new edition has an extra 32 pages allowing several groups more space and completely or partly new plates with more detailed text: grouse, loons, several groups of raptors, terns, owls, swifts, woodpeckers, swallows, redstarts and some other relatives to the flycatchers (formerly often called ‘small thrushes’), tits and a few finches and buntings are some of these. More than 50 plates are either new or have been repainted, completely or partly. Apart from this, a few new vignettes have been added. The section with vagrants has been expanded to accommodate more images and longer texts for several species. The entire text and all maps have of course also been revised.
