Distribution

Introduction

Occurs in montane forest from northern Mexico (northwestern Chihuahua in the Sierra Madre Occidental, Monterrey in the Sierra Madre Oriental) south through Central America (Guatemala, Honduras, El Salvador, northern Nicaragua, Costa Rica and Panama) and northern South America (Venezuela, Colombia, Ecuador, Peru) to south-central Bolivia (Chuquisaca Department), including the tepuis of southern Venezuela and adjacent northern Brazil and western Guyana (25, 4, 27, 28). A small, disjunct, and apparently migratory breeding population has recently become established in the Sierra del Carmen, Coahuila, in northeastern Mexico (29, 30). One record from Baritú National Park in northern Argentina probably represents a wandering vagrant from Bolivia (31). Similarly, occasional records from the southwestern United States (32, 5) usually represent vagrants from populations in northern Mexico. The only confirmed nesting records from the United States involve a female that built nests in both 2016 and 2017 in Pinery Canyon, Cochise County, Arizona . In 2016 it apparently hybridized with a male Painted Redstart (Myioborus pictus) and successfully fledged three hybrid offspring (26, 33; see Related Species). In 2019, a pair of Slate-throated Redstart was consistently present along the Boot Canyon trail at Big Bend National Park in South Texas from May–August and may have nested (eBird: S69992043).

Historical Changes to the Distribution

The recent establishment of a breeding population in the Sierra del Carmen of northeast Mexico (29, 30), along with recent confirmed or probable nesting records from the southwestern United States (26, 33; see Distribution) suggest that a northward expansion of the breeding range may be in progress.

Abundance

Relative abundance is depicted for each season along a color gradient from a light color indicating lower relative abundance to a dark color indicating a higher relative abundance. Relative abundance is the estimated average count of individuals detected by an eBirder during a 1 hour, 1 kilometer traveling checklist at the optimal time of day for each species.   Learn more about this data
