Tocantins River
The range of the yellow-browed tody-flycatcher is mainly in the southern Amazon Basin, and in the east limited by the Amazon River; in the southeast, its range extends eastward including Ilha de Marajo and the last downstream region of only the Tocantins River, of the Araguaia-Tocantins River system. This southeast extension of the range ends in central-(northern) Maranhão state, in the Baia de Sao Marcos region at the Atlantic Ocean.
