Stummelschwanztyrann Muscigralla brevicauda

A small, oddly-shaped flycatcher that inhabits deserts and other arid habitats. It is found mainly west of the Andes, but ranges up into interior valleys in a few areas. Short tail, long legs, and stout bill give this bird a top-heavy appearance; pale wingbars and facial markings also help separate it from other drab species like Grayish Miner. Chestnut-and-buff rump is usually hidden by the wings, and yellow crown patch is almost never visible in the field. Largely terrestrial, but also regularly sits up on bushes, rocks, posts, and other exposed perches.
