Although this book was brand new in 2010, it has recently (2017) been substantially updated providing details of many more of the best birding sites in the area. The original showed you in the clearest possible way, exactly where to go to look for the most exciting birds of northern Spain – Wallcreepers, Lammergeiers, Great Bustards, Little Bustards, Snowfinches, Black Woodpeckers, Dupont's Larks – and this new version gives you even more precise information on where to find many of these birds.
