In 1998, biologist David Norman published a delightful guide to the common amphibians of Costa Rica, packed with his wonderful and detailed illustrations and observations on the species’ natural history. I had the pleasure of working with David for a couple of years, publishing a magazine and having great discussions with him about biology and conservation in Costa Rica’s Northern Zone. I had the pleasure of providing 13 species photographs and some support to this project through the Environmental Management Office, in Upala, where I was working at that time. David is a passionate biologist and conservationists, and his little guide and other publications, published both in Spanish and in English, are still available for purchase.  I found a good supply of copies at the La Selva Biological Station bookstore.
