Graumaskentyrann Empidonomus aurantioatrocristatus

Medium-sized, grayish flycatcher, commonly encountered in the canopy of tall forest. One of the more prominent Austral migrants in South America, with the bulk of the population moving into the Amazon basin during the Austral winter, becoming a common sight from canopy towers. During the Austral summer, it prefers deciduous and semi-humid forests. Size, overall grayish coloration, darker cap and eyeline, and brownish tinge on the back make this species easy to identify. Generally quiet for a flycatcher; its high-pitched, buzzy song is mostly heard on the breeding grounds.
