30 pictures and videos, 20 seconds to watch each one, and sounds of all the birds of the Western Palearctic, will appear in front of the most daring birders that will try to guess the maximum number of species. Do you think anybody will guess correctly all the species? Do you dare to guess them?
Lynx Edicions will be the sponsor of the ID Challenge another year. They will award the winners with three prizes that any good birder has to have in his bookcase: a volume of the Handbook of the Birds of the World for the winner and other outstanding publications for the second and third classified.
