`... a must for anyone with an interest in neotropical birds' David Tomlinson, New Scientist, August 1995`This guide is a major contribution to field ornithology and birding in Mexico and northern Central America. Most highly recommended.' Wildlife Activist, No. 25, December 1995`Few, however, who actually looked at this book would question its importance, as it radiates authority and excellence. One of its most prominent features is the sheer quantity of information not available from any of the region's comparable field guides ... maps are a highly commendable ... the plates are very good; they are accurate in plumage details and postures, and species within a plate are to scale. Especially striking are the plates depicting cryptically plumaged species such as owls (plates 25 and 26), nightjars (plate 27) and sparrows (plates 63 and 64) ... wealth of information presented and its excellence. Few guides are better value for money: produced on good quality paper with 71 colour plates, the softback edition costs only £25.00. It will quickly become the main guide to the region's birds.' Adrian Long, The Ibis, 1996, Vol. 138`impressive book ... As a guide to one of the ornithologically richest parts of the world, this book is unlikely to be superseded for a very long time.' Bulletin of the British Ornithologists' Club, Volume 115, No. 3, September 1995`This is a first-class book by any standards and will clearly not be superseded in the foreseeable future.' Bryan Sage, Country-Side, October-November 1995`the book is well researched, produced, and published, a valuable addition to any birdwatcher's library ... a most invaluable resource' Jack Siegel, Nature Canada, Autumn 1996`...The result of this immense labor is not just a very fine field guide, but also a manual to the birds of Mexico and northern central America. This extraordinary achievement is not likely to be improved in the near future...This wonderful book treats about 1070 species...the maps in Howell and Webb are excellent....mandatory reading not only for all birders but also for some professional ornithologists...superb, extremely well-prepared species accounts, its very clear range maps, and its magnificent plates, which are beautifully reproduced, all converge towards making this book an exceptional volume' Ornitologia Neotropical (1997) 8: 195-236
