Typical Antbirds (Thamnophilidae)

Undulated Antshrike (Frederickena unduligera)

French: Batara ondé German: Dunkelbrauner Ameisenwürger Spanish: Batará Ondulado

Taxonomy: Thamnophilus unduliger Pelzeln, 1868, Rio Içanna, north-west Brazil.
Genus presumed related to Thamnophilus on basis of external morphology, especially the strongly hooked bill, but supporting molecular or other evidence unavailable. Considered to form a superspecies with F. viridis. Races defined on basis of female plumages, but racial assignment of specimens often difficult because of extensive individual (though possibly age-related) variation, even among females from same locality; geographical limits of fulva and diversa are based on preliminary vocal analysis; re-examination of taxa required, and molecular and vocal analysis l..

Taxonomy: Thamnophilus unduliger Pelzeln,1868. Rio Içanna, north-west Brazil.
Genus presumed related to Thamnophilus on basis of external morphology, especially the strongly hooked bill, but supporting molecular or other evidence unavailable. Considered to form a superspecies with F. viridis. Races defined on basis of female plumages, but racial assignment of specimens often difficult because of extensive individual (though possibly age-related) variation, even among females from same locality; geographical limits of fulva and diversa are based on preliminary vocal analysis; re-examination of taxa required, and molecular and vocal analysis likely to prove most useful. Four subspecies recognized.

Subspecies and Distribution:

  • unduligera (Pelzeln, 1868) - NW Amazonian Brazil on upper R Negro, possibly extending S to N bank of R Solimões.
  • fulva J. T. Zimmer, 1944 - SE Colombia (E Cauca, W Caquetá, W Putumayo), E Ecuador and E Peru (N of R Marañón and R Amazon), possibly extending E into Brazil (Amazonas N of R Solimões).
  • diversa J. T. Zimmer, 1944 - E Peru (S of R Marañón and R Amazon) and NW Bolivia (S La Paz, extreme S Beni).
  • pallida J. T. Zimmer, 1944 - SW Amazonian Brazil (Amazonas S of R Amazon), probably also NC Bolivia (E Pando).
