灰蚁鵙

The cinereous antshrike (Thamnomanes caesius) is a small, insectivorous bird in the family Thamnophilidae, found across Amazonia and the Orinoco basin in South America. It ranges from Venezuela, Colombia, and the Guianas south through Brazil to Bolivia and Peru. This species is a characteristic member of Amazonian mixed-species foraging flocks, in which it serves as a sentinel, alerting other species to approaching predators while also flushing insects for other flock members. It inhabits the undergrowth and lower to mid strata of terra firme and humid forest, particularly avoiding seasonally flooded várzea. The male is largely gray-blue with a black throat, while the female is brownish with a rufous wash. The cinereous antshrike is classified as Least Concern by the IUCN, with a vast Amazonian range and stable populations in intact forest. As a nuclear species in mixed-species flocks, its presence or absence has cascading effects on the diversity and composition of the flocking community. Deforestation of Amazonian terra firme forest poses the primary long-term threat to this and many co-occurring antbird species. The species is entirely absent from Europe; any database record listing Norway as its range is an artifact of data entry error.
