Falcons and Caracaras (Falconidae)
Barred Forest-falcon (Micrastur ruficollis) - HBW 2, p. 253
French: Carnifex barré
German: Sperberwaldfalke
Spanish: Halcón montés Agavilanado
Taxonomy: Sparvius ruficollis Vieillot, 1817, South America = Rio de Janeiro.
Distinctive genus specialized for life in dense forest: long tail and short wings for manoeuvrability; large ear openings and facial ruff indicate importance of hunting by sound. Most closely related to Herpetotheres. Until recently considered to include M. gilvicollis, but voice and morphology support specific status for M. gilvicollis, which is widely sympatric with present species. Possible races oaxacae and kalinowskii currently included in races guerilla and zonothorax respectively. Six subspecies normally recognized.
