The third edition of the first guide to treat the 386 species that are regularly present or occasional in Catalonia, the Community of Valencia, the Balearic Islands, North Catalonia, Andorra and the Aragonese Strip. It contains 1,033 illustrations which permit the identification of plumage according to sex and age, including recently established exotic species. The texts and 323 distribution maps contain the most up-to-date information available.
Each species is covered in the following sections: illustration, text, map and QR code. The information is presented on double-page spreads, allowing easy consultation of the various characteristics.
The text includes the Catalan name and the scientific name (indicating those cases where names are different in the Community of Valencia or the Balearic Islands), size, differences in plumage of similar species, voice, ecological requisites, distribution in the Western Palearctic and in the territory covered by the guide, as well as population size and tendency.
The QR code links directly to the Internet Bird Collection (IBC) web page of each species, where a photo gallery, videos and sound recordings complement the information provided in the guide.
