Costa Rica has so many wonderful birds that Rainforst Publications created this guide just for the birds of the Central Valley, also known as the Greater Metropolitan Area. There have been many changes in the avifauna of this area due to habitat modification and fragmentation and numerous species have sought alternative areas or expanded their distribution. This guide can help residents and visitors identify and keep a record of the avifauna currently associated with urban ecosystems and to help protect the Central Valley habitat. Rainforest Publications fold-out field guides are both particularly portable and rich with information. They are well designed and highly usable. The 14 'pages' are approx. 24" x 8.75" (61 x 22cm) when spread flat (double sided); and fold into only approx. 3.5" x 8.75" (9 x 22cm), which is perfect for slipping into your pocket or backpack. Robert Dean's illustrations are gorgeous, full color, detailed, and scientifically accurate. Illustrations are accompanied by the scientific name of each bird, its' common name in English and Spanish, and the typical size of the bird. The illustrations are printed with fade-resistant inks and covered with UV resistant film that is waterproof. The guides are both flexible and durable, and designed for years of use both on your trips and as a quick reference when at home.
