Costa Rica 2012 Book

My book of photos from Costa Rica is available now at my Blurb bookstore. This book presents an overview of an intensive birding trip to Costa Rica. The 100+ photos are a great introduction to Costa Rica's birds and ecological zones, showcasing shorebirds on the western coast, the quetzals of the Talamanca Higlands, tropical diversity at La Selva, and a sampler of hummingbirds in the Central Volcanic mountain range.

This year so far
