brasiltyrann Myiarchus ferox

Fairly large flycatcher, mostly gray-brown above with a pale throat and pale yellow belly. Different subspecies vary in the tone of the upperparts, which may be warm or cold toned but all have dark bills. Found in savannas, semi-open woodlands, and at forest edges. Best distinguished from similar flycatchers by call: a short “police-officer” whistle “prrrih.”
