This pocket guide is a double sided 560mm x 21mm sheet of water resistant paper folded concertina style to 100mm x 21mm. It shows about 170 of the common birds of Mexico in breeding plumage with common and Latin names plus size. The birds are split into six sections; `waterside and nearshore', `doves woodpeckers etc.', `parrots and hummingbirds etc.', `raptors', `owls' and `perching birds'. If you are travelling light this is an ideal reference guide but you will need access to other material to sort out the females and less common birds.
