March 20, 2017 – Sharp-tailed Tyrant or Sharp-tailed Grass Tyrant (Culicivora caudacuta)

These tyrant flycatchers are found in northern Bolivia, southern Brazil, and parts of Paraguay, Uruguay, and Argentina. Their preferred habitat is older grassland, with grass of up to 6.5 feet (2 meters) tall. Though their diet is primarily insects, they also feed on grass and other plant seeds, unlike other tyrant flycatchers. Often seen alone or in pairs, they are sometimes observed in small groups of between three and seven birds. Their elaborate cup-shaped nests are constructed in clumps of grass. Listed as Vulnerable by the IUCN, their population is decreasing due to habitat loss and degradation caused by farming, overgrazing, and frequent fires.
