Black-bellied thorntail

The black-bellied thorntail (Discosura langsdorffi) is a slow flying species of hummingbird in the family Trochilidae.[2] It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest at about a 100-300m altitude.[3] It stays high in the forest which explains the lack of scientific information on it.[4] The male will attract the female by fanning out their tail and zooming side-to-side with a loud cracking sound.[2] Generally they'd only make a quick “tsip” or “chip” noise when feeding.[3]
