A Dry tropical forest, habitat for several different species
The area of Tempisque receives its name due to Costa Rica’s largest river: Tempisque River. Bisecting Guanacaste, it separates the white sandy coast of Nicoya Peninsula from the mainland and offers an extensive variety of tropical wildlife at the river banks. The Tempisque River's dry tropical forest is an important habitat for several different species of monkeys, crocodiles, iguanas, and migratory and aquatic birds such as the roseate spoonbill, white ibis, greets egret, little blue heron, among others. The variety of birds in this region is the most extensive in the entire country.
The southern leg of the river passes through the Palo Verde National Park, a legitimate bird watching paradise, encompassing mangroves, swamp and both fresh water and salt water lagoons. Palo Verde can be explored by fot, bicycle or by boat. It's highly recommended a boat tour since it gives you the opportunity to visit Isla Pajaros (Birds Island), in the middle of the Tempisque River, which is the largest nesting site in Costa Rica for the black-crowned night-heron.
