My first “big book” that I researched, wrote and illustrated was A Field Guide to the Mammals of Central America and Southeast Mexico, published in 1997 by Oxford University Press. Now, 12 years later, a second edition is about to be released. It has numerous updates, and I am hoping above all that it has more accurately reproduced color illustrations. I just received a copy of the cover from OUP, and here it is, below.
The book should be available in May or June 2009, the price has dropped to $45.00 US, so pick up a copy soon!
