Spend this holiday season where the rainforest meets the sea, in the most spectacular and underbirded corner of Costa Rica. [caption id="attachment_3853" align="alignleft" width="204" caption="A Gartered Trogon sits perched atop a tree in the Osa Peninsula"][/caption] The Osa Peninsula harbors over 460 species of birds including the healthiest population of Scarlet Macaws in Central America, three species of leking Manakins, Yellow-billed and Turquoise Cotingas, King Vultures and the Osa endemic BCAT. Migrant birds that frequent the Osa Peninsula include the Golden-winged Warbler, Olive-sided Flycatcher, Prothonotary Warbler and the Baltimore Oriole. Home to the largest remaining tract of tropical lowland rainforest and intact mangrove ecosystems along the tropical Pacific coast of Central America, the Osa Peninsula is the wildest and most magnificent region of Costa Rica.
