The Yellow-bellied Flycatcher (Empidonax flaviventris) breeds across the boreal forest from eastern interior alaska to Newfoundland and migrates through the eastern United States, including eastern Texas, to winter in central america (Oberholser 1974, Gross and Lowther 2011). It is rare west of central Texas (Oberholser 1974), with records from Big Bend National Park, Brewster county (Oberholser 1974; two specimens, 3 September 1968 and 1 September 1969), the Davis Mountains (Peterson and Zimmer 1998; 1 September 1994), and Balmorhea State Park, reeves county (Lockwood 2015; fall record with no date). The species is rare in adjacent New Mexico, with 28 individuals reported to the New Mexico Bird records committee, all from the far eastern counties of Eddy, De Baca, and roosevelt in fall migration (29 august–6 October, Sandy O. Williams III, pers. comm.). Farther west in arizona, california, and Nevada the species is a vagrant, with all records from late august to mid-October (Phillips et al. 1964, hamilton et al. 2007, Sullivan et al. 2009, https://ebird.org/), except for an exceptional mid-winter and an early June record from arizona (rosenberg and Witzeman 1999, rosenberg et al. 2017). The Yellow-bellied Flycatcher is unrecorded from the El Paso region comprising El Pasocounty, western hudspeth county, and southern Doña ana county (New Mexico) (Paton et al. 2012). although not a comprehensive source, the eBird citizen-science database contains no records for the Trans-Pecos region of Texas; its westernmost Texas record is from Midland county (Sullivan et al. 2009, https://ebird.org/).
