Spotted
The Olivaceous Thornbill is a high-Andean hummingbird known for its subdued, olive-green plumage. Unlike many hummingbirds, it lacks brightly iridescent throat patches, making its overall appearance rather understated. It prefers dense, humid montane habitats.
Where to spot
Endemic to the eastern Andes of Peru, it primarily inhabits humid montane forests, cloud forests, and elfin forest edges. It is typically found at elevations ranging from 2,300 to 3,700 meters (7,500-12,100 feet).
How to spot
Its lack of bright iridescence is a key identification feature. Look for a small, olive-green hummingbird with a short, straight black bill. It often forages low in the undergrowth or at mid-story levels, feeding from small flowers. Patience is key due to its camouflaged appearance.
When to spot
Active throughout the day, year-round. Prime observation times are dawn and dusk when they feed actively. They may be less active during the middle of the day or in inclement weather.

Unlike many flashy hummingbirds, the Olivaceous Thornbill relies on camouflage to blend into its dense, mossy habitat. Its subtle coloring makes it surprisingly difficult to spot despite its activity.
