Medium-sized Myiarchus flycatcher very similar to Ash-throated Flycatcher of western North America but slightly brighter overall, with bushier crest and browner face. Best identified by voice. Ash-throated is a winter migrant throughout much of Nutting’s range. One form of Nutting’s occurs in arid scrub and oak woods of lowlands and foothills; its commonest calls are a loud “wheek” and bickering “kwidik-kwidik.” A second form of Nutting’s (“Ridgway’s Flycatcher”) occurs in hedges and semiopen country in lowlands from Chiapas south to Central America; its commonest calls are “wh’beer” and “dee-dee-dee-dee.”
