オリーブヒタキモドキ Myiarchus tuberculifer

Medium-sized flycatcher; rather small and slender for a Myiarchus. Extremely similar to other Myiarchus flycatchers and most easily identified by voice: listen for the plaintive, sad “wheer” call. Also note relatively dark crown, slender bill, fairly bright yellow belly, and rufous edges on secondaries. Some variation across range, but underside of tail usually quite dark, with little or no rufous. Widespread and common in Middle and South America, barely extending into the southwest U.S. Occurs in a variety of forested and semiopen habitats including oak-lined canyons, humid rainforest edges, and gardens.
