It's the most usefull book I own related with the mammalfauna proyects ( inventories, education, management ) we are doing in Central and Western Colombia. Every aspect of the text and illustrations has proven to be very usefull and practical. The taxonomical descriptions are generaly good enough to clasify the bigger species in the field, and the habit and habitat descriptions coincide mostly with our own experiences. The distributionmaps included in the text are also very usefull. The illustrations are sometime a little small, but have proven to be easily recognized by the local habitants, what is extremely usefull during quick inventaries. The relation price-quality is outstanding
