Eutoxeres aquila
The White-tipped Sicklebill (Eutoxeres aquila) is a distinctive medium-sized hummingbird immediately recognizable by its dramatically decurved, dark sickle-shaped bill, which sets it apart from almost all other avian species. Measuring approximately 11-14 cm in length, including its formidable bill of 3.5-4.5 cm, and weighing 8-12 grams, its plumage is a rather subdued olive-green on the upperparts, contrasting with heavily streaked white and dull green underparts. A key field mark, besides t...
Found primarily in humid foothill and lower montane forests, cloud forests, and dense secondary growth, favoring areas with abundant understory and large-leaved plants. It typically occurs at elevations ranging from near sea level up to 2500 meters.
Exclusively feeds on nectar, predominantly from large, curved Heliconia flowers, which its specialized bill perfectly matches. It also gleans small insects and spiders from foliage to supplement its diet, especially during breeding season.
The White-tipped Sicklebill is largely solitary and diurnal, often observed performing a 'traplining' foraging strategy, systematically visiting a circuit of favored nectar sources. Its flight is direct and buzz-like, often appearing more like a large bee or insect due to its unique bill and wing...
The White-tipped Sicklebill has a wide distribution across Central and South America, primarily inhabiting the humid lowlands and foothills. Its range extends from Costa Rica and Panama, south through the Andes of western Colombia, western Ecuador, and into northern Peru. East of the Andes, isola...
