Córdoba, Veracruz, Mexico


Formerly considered conspecific with F. analis (which see), but differs in both plumage and song. Race pallidus originally described in genus Furnarius, in error; this mistake was emended in index to same volume#R#R, but index not published until 1883 so does not form part of original description. Three subspecies recognized.

Subspecies and Distribution
  • F. m. moniliger P. L. Sclater, 1857 – Caribbean slope from S Mexico (S from C Veracruz) E to Guatemala (except Petén).
  • F. m. pallidus (Lawrence, 1882) – Yucatán Peninsula (in SE Yucatán, Campeche and Quintana Roo) and N Guatemala (N Petén).
  • F. m. intermedius Ridgway, 1908 – E Guatemala (presumed), Belize and NW Honduras.
