Schwarzkinn-Schattenkolibri Threnetes leucurus

Scarce hummingbird that looks similar to a hermit. Look for buffy patch across the base of the neck, bold whitish flashes in the tail, and a fairly long, slightly decurved bill. Face pattern is rather diffuse, but look for the whitish mustache and pale line behind the eye. Found in the understory of forest and edges in lowlands and foothills below around 1,100 m where it stays low, quickly zipping around flower patches.
