Similar species
Has a narrower bill and is generally slimmer and longer-winged than Pacific-slope Flycatcher. Pine is generally greyish instead of yellowish; its eyering is whitish rather than yellowish. Also note the less contrasting wingbars: pale fringes may be largely absent from the tertials but are often obvious in Pacific-slope. As with most Empidonax Flycatcher the vocalisation is a main key for identification.
Likely to overlap with Acadian Flycatcher, Alder Flycatcher, Buff-breasted Flycatcher, Cordilleran Flycatcher, Dusky Flycatcher, Gray Flycatcher, Hammond's Flycatcher, Least Flycatcher, Pacific-slope Flycatcher, White-throated Flycatcher, Willow Flycatcher, Yellow-bellied Flycatcher, Yellowish Flycatcher.

Distribution
Guatemala and Mexico.
A fairly common but localized species.
Taxonomy
Some vocal differences between populations south and north of the Isthmus of Tehuantepec (Mexico) indicate that more than one species may be involved.
Subspecies
Clements recognises the following subspecies [1]:
- E. a. pulverius in oak-pine forests of northwest Mexico (Sinaloa to Jalisco)
- E. a. trepidus in northern Mexico (Coahuila and Tamaulipas); winters to Guatemala
- E. a. affinis in pine forests of Mexican plateau (Michoacán to Puebla)
- E. a. bairdi in pine forests of south Mexico (Guerrero, Oaxaca and Chiapas)
- E. a. vigensis in oak-pine forests of east Mexico (Veracruz)
Habitat
Pine-oak forest from 1600 to 3500 m.
Behaviour
Diet
Feeds on insects.
Forages similar to Hammond's Flycatcher at all levels of forest.
Breeding
Poorly known. Territorial birds reported in Chiapas in late May. The nest is a cup placed in a tree fork at middle level of the forest.
Movements
Mainly a resident species. Some local wandering in autumn and winter, particularly birds in the northern parts of its range.
