Rising from near sea level to over 3,300 m, the enormous wilderness area of La Amistad International Park contains the highest number of endangered and endemic birds of any IBA in Panama. Extending from the Costa Rican border in the drainage of the Yorkin River, in Bocas del Toro the park includes the headwaters of the Changuinola River and its Teribe, Culubre and Changuena tributaries. On the Pacific slope in Chiriquí, the park boundary follows the 2,000 (above Santa Clara), 2,200 (above Cerro Punta) and 1,800 m contours (above Boquete). The lowest point in the park is at Boca Chica (90 m) in the Changuinola Valley, while Cerro Fabrega (3,335 m), the second highest peak in Panama after Volcán Barú, is the highest. Most people living inside the park belong to the Teribe and Ngöbe indigenous groups, but with some colonization by mestizos on the Chiriquí side. The only areas of the park easily visited are Los Nubes (park headquarters) and the Los Quetzales Cabins, both near Cerro Punta on the Chiriquí side. Access to the Caribbean slope is difficult, and most of its foothill and highland areas, including Cerro Fabrega, has never been ornithologically surveyed.
La Amistad is one of the most important strongholds for the globally threatened Bare-necked Umbrellabird and Three-wattled Bellbird. Other globally threatened and near-threatened species include Harpy and Crested Eagle, Black Guan, Great Curassow, Great Green Macaw, Red-fronted Parrotlet, Resplendent Quetzal and Blue-and-gold Tanager. An additional 76 nationally threatened species also occur. The park contains 47 of 54 species (87%) of the Costa Rica and Panama Highlands EBA, as well as 9 of 11 species (82%) of the Central American Caribbean Slope EBA. On the Chiriquí side, however, the boundary is too high to include any endemics of the Southern Central American Pacific Slope EBA. With 56 endemic species, La Amistad may have one of the highest totals of any area in the world. The site also includes 48 of 68 species (71%) of the N06 biome, and 17 of 42 species (40%) of the N05 biome.
