Pine Flycatcher - BirdForum Opus

Empidonax affinis

Identification

  • Pale greyish lores
  • Whitish teardrop-shaped eye-ring, extending to point behind eye
  • Olive to greyish-olive crown, head side, nape and upperparts
  • Dusky wings with whitish to buff wingbars
  • Pale yellow panel on secondaries (when wing closed)
  • Dusky tail
  • Pale greyish-yellow throat

Sexes similar. Juveniles have buffy wingbars. Empidonax affinis (PIne Flycatcher).jpg

Similar species

Has a narrower bill and is generally slimmer and longer-winged than Pacific-slope Flycatcher. Also note the less contrasting winbars and the thicker eyering. As with most Empidonax Flycatcher the vocalisation is a main key for identification.

Distribution

Guatemala and Mexico.
A fairly common but localized species.

Taxonomy

Five subspecies recognized:

  • 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)

Some vocal differences between populations south and north of the Isthmus of Tehuantepec may indicate that more than one species may be involved.

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.
