The Travel Guide to the Peninsula de Nicoya, Costa Rica, with detailed Maps, Hotels and Tourist Information
The Palo Verde National Park on the banks of the Rio Tempisque is one of the best wildlife and bird watching spots in Costa Rica. The remote wetland sanctuary harbors one of Central Americas largest concentration of aquatic » birds and is the most important migratory bird site of the Mesoamerican Pacific.
Hemmed in by limestone hills and rivers, the lowlands of the Tempisque basin become a vast
area of wetlands in rainy season.
Towards the end of the rainy season Palo Verde is home to at least 250,000 birds.
For » birdwatching in Palo Verde the dry season, from Jan - April, is the best time because waters largely subside and the park's many birds cluster by the remaining marshes and waterholes. Observing the fauna is particularly good because in dry season there is little vegetation to obstruct views of the roosting birds.
Palo Verde is also important for protecting one of the last significant remnants of the deciduous dry forests of the Neotropics. The sensible eco-system of the tropical dry forest once covered most of the Central American Pacific side but has been destroyed by man over the centuries.
With little or no precipitation for half the year, most bushes and trees in the dry forest shed their leaves to conserve water. At the peak of dry season however, many trees burst into a riot of colors boasting bright yellow and red flowers on bare branches.
Palo Verde forms part of the Tempisque Conservation Area which includes the Barra Honda National Park, the Caballero Wildlife Refuge, the Lomas Barbudal Biological Reserve and other patches of biological interest. The total of protected areas in the Tempisque river basin encompasses 73,000 hectares and presents 15 different habitats thus being one of Costa Rica's most biological diverse sites.
Around 75 species of » mammals, including peccaries, armadillos, deer, monkeys, and coatis roam the thickets. Palo Verde harbours Costa Rica's largest population of » jaguarundis, a brownish, small wild cat. 55 species of reptiles and amphibians are found, and the Tempisque river has the largest concentration of crocodiles in Costa Rica.
The abundance of flowers and fruit in the national park also feed myriads of insects and colonies of » bats. Especially the Lomas Barbudal Biological Reserve, adjacent to Palo Verde, is a heaven for insectologist's: 250 species of bees have been counted which is around a quarter of the world's bee species. An abundance of wasps, butterflies, moths and other insects inhabit the forest, and in - in rainy season - there are swarms of mosquitoes.
