Sığır Tiranı Machetornis rixosa

Medium sized flycatcher with fairly widespread range in South America. Superficially resembles a Tropical Kingbird with olive-brown back, yellow belly, and grayish crown. However, Cattle Tyrant is unique for typically being found on or near the ground, where pairs or small flocks follow grazing animals. Found in open habitats including farmland and marshes.
