Las Cruces Biological Station

Birdwatching at Las Cruces Biological Station & Wilson Botanical Garden

Located in the scenic Coto Brus Valley near San Vito in southern Costa Rica, Las Cruces Biological Station is one of the country’s most compelling destinations for birdwatchers. Operated by the Organization for Tropical Studies (OTS), the station is best known as the home of the renowned Wilson Botanical Garden, which features one of the most diverse and scientifically significant plant collections in Central America.

Set at an elevation of approximately 1,200 meters (3,900 feet), Las Cruces sits at the interface of montane and lowland forest zones, creating a unique blend of habitats that supports a rich diversity of bird species. The station’s network of well-maintained trails weaves through secondary forest, regenerating areas, open gardens, and forest edges ideal for spotting everything from fiery-billed aracaris, rufous-breasted wrens, and white-crested coquettes to mixed-species flocks of tanagers and flycatchers. Early mornings are particularly active, with birds foraging at eye level, while the botanical gardens come alive throughout the day as hummingbirds, euphonias, and flowerpiercers are drawn to the abundant blooms.
