Guanacaste, this region provides a much different and dryer habitat than other bird havens (like the Central Valley, the Caribbean or the Osa Peninsula), so here you can expect to find lots of unique species that you might not be able to easily find anywhere else. Some good opportunity to see various of birds in nature are the protected areas like the National Parks where many tours are offered during November and April. Because of its various of landscapes Guanacaste is an ideal area to observe exotic animals.
Palo Verde National Park
In the middle of Costa Rica's hottest and driest region, the floodplains of the Rio Tempisque form an extensive and diverse patchwork of habitats including fresh and saltwater marshes, lagoons,
lakes, savanna woodlands and forests. Within the marsh, such species as the black-bellied whistling duck, the blue-winged teal and northern jacana have been observed by the thousands.
Teal, geese and ducks arrive from North America to winter in the park each year, along with many neotropical migrants, including hummingbirds, flycatchers, warblers, tanagers, orioles, vireos, owls, and falcons.
Tempisque River Tour
A boat tour along the Tempisque River is a popular way of exploring the bird life of the mangrove forests. Nesting colonies of boat-bill heron are easily spotted, along with little-blue herons, yellow-crowned herons and others. The Tempisque River has a 4-m rise and fall with the tide. Crocodiles and caimans can often be seen on its banks.
