Long - tailed Sylph
Sylphs (Aglaiocercus) are short-billed, long-tailed hummingbirds of humid montane forests of the Andes. The Long-tailed Sylph is the most widespread member of the genus, and occurs from Venezuela south to Bolivia.
This is the only species of sylph on the east slopes of the Andes. In Colombia and Ecuador, it also is found on the western slopes of the Andes; here it overlaps geographically with the Violet-tailed Sylph, but the Violet-tailed usually occurs at lower elevations.
This species forages at all heights in the forest, and at forest edge. The nest of the Long-tailed Sylph is in a suspended ball or clump of moss, with a side entrance and tail of moss dangling below.
