Palo Verde National Park
Palo Verde National Park is located on the Pacific slopes of Guanacaste Province in Northwestern Costa
Rica (10° 21' N, 85° 21 W).
The 19,000-hectare (46,950 acres) park has seasonally dry forest on limestone outcrops and extensive wetland vegetation bordering the Tempisque River that flows into the Gulf of Nicoya. This area includes some of the best patches of dry forest remaining in Central America, with giant Pochote, Cedro and Guanacaste trees. The freshwater marsh in front of the Station is an important feeding ground for 60 species of resident and migratory water birds.
Within the marsh, such species as the black-bellied whistling duck and the blue-winged teal have been observed by the thousands. The Park is also a principal wintering ground for many neotropical migrants, including hummingbirds, flycatchers, warblers, tanagers,orioles, vireos, owls, and falcons. The mammal fauna is equally rich and visible, particularly during the dry season when peccaries, armadillos, jaguarundis, coatis, agoutis, deer, and monkeys are attracted to the water holes.
