Tanagers and Pygmy-Owls
This area contains one of the highest concentrations of range-restricted species in the world. No fewer than 60 endemic species depend on the region’s wet forests. Among the birds recorded at the Tanagers Reserve are globally threatened species such as the Choco Vireo and Gold-ringed Tanager, both Endangered; and the Cloud-forest Pygmy-owl, Black-and-gold Tanager, and Giant Antpitta, all of which are Vulnerable.
Golden-winged Warblers are specialists, requiring “young,” or early-successional, forests for breeding. Once their young leave the nest, the birds need mature forests for foraging nearby.
Golden-winged Warblers also suffer from competition and hybridization with Blue-winged Warblers; parasitism by cowbirds, which lay their eggs in the warbler’s nests; and loss of wintering habitat in Latin America.
