The inner tail feathers are very short and the outer ones very long. Voice: The long-tailed sylph's apparent song is "a continuous series of buzzy notes 'bzzt...bzzt...bzzt...'." Its calls include "a repeated, short, buzzy or raspy 'dzzrt'...a more drawn-out, higher-pitched 'bzzeeew' a thin high-pitched rising twittering."
