Yellow Tyrannulet Capsiempis flaveola Scientific name definitions

The Yellow Tyrannulet is a unique yellowish flycatcher with a patchy distribution in southern Central and northern South America. With olive upperparts, yellow underparts, a long tail, and horizontal posture it resembles the doraditos (Pseudocolopteryx), except for its yellower face and neck. Its calls are bubbly and cheerful and include series of whistled notes and sputtery trills. It forages actively for arthropods in dense vegetation, generally in pairs or small groups. It avoids tall forest, preferring openings and edges with copious amounts of dense vegetation at low levels. It shows a particular fondness for bamboo.

Not globally threatened (Least Concern). Uncommon to common. Occurs in many national parks and other protected areas throughout its extensive range, e.g. Río Negro Jaguar Reserve and Tarcol Lodge, in Costa Rica, Río Claro Reserve and Tinigua National Park, in Colombia, Machalilla National Park and Río Palenque Science Centre, in Ecuador, Pacaya-Samiria National Reserve, in Peru, Caaguazú, San Rafael and Ybycuí National Parks, all in Paraguay, and Iguaçu, Itatiaia, Serra da Canastra and Tapajós National Parks, all in Brazil. Given its tolerance of converted habitats and secondary habitats, this species is not considered likely to become threatened in near future.
