Eutoxeres condamini
The Buff-tailed Sicklebill (Eutoxeres condamini) is a distinctive medium-sized hummingbird, immediately recognizable by its extraordinarily decurved, sickle-shaped bill, a marvel of avian adaptation. Measuring approximately 13-15 cm (5-6 inches) in length, including its prominent bill, and weighing 8-12 grams, this species exhibits generally dull green upperparts, a streaked buff and greenish belly, and conspicuously buffy undertail coverts that give it its common name. A subtle white stripe ...
Found in humid foothill and lower montane forests, forest edges, and dense understory, often near streams, typically at elevations between 500 and 1800 meters.
Primarily feeds on nectar from specialized, strongly curved flowers, particularly Heliconia and Centropogon species, supplemented with small spiders and insects gleaned from foliage.
Buff-tailed Sicklebills are generally solitary and diurnal, actively foraging during daylight hours. Their unique bill is perfectly adapted for probing deeply into the strongly curved flowers of certain plant species, primarily Heliconia and Centropogon, often employing a 'traplining' strategy wh...
The Buff-tailed Sicklebill is resident across a significant portion of the northern and central Andes in South America. Its primary breeding range extends from southern Colombia through Ecuador and Peru, reaching into northern Bolivia. This species is specifically adapted to the humid foothill an...
Least Concern
