About the Yellow-billed Cacique

The yellow-billed cacique (Amblycercus holosericeus) is a species of bird in the family Icteridae. It is found in Mexico, every Central American country, Bolivia, Colombia, Ecuador, Peru, and Venezuela. The yellow-billed cacique was formally described in 1830 with the binomial Sturnus holosericieus. In 1851 Jean Cabanis erected the genus Amblycercus with it as the type species. For part of the twentieth century it was assigned to genus Cacicus but by the end of the century had been firmly placed back in Amblycercus. It is basal to the oropendolas and caciques but is not closely related to any of them.

The yellow-billed cacique is the only member of its genus and has these three subspecies: Amblycercus holosericeus holosericeus (Deppe, 1830) Amblycercus holosericeus flavirostris Chapman, 1915 Amblycercus holosericeus australis Chapman, 1919

Some authors have suggested that A. h. australis might warrant full species status. The Clements taxonomy draws some distinction within the species, calling A. h. australis the "yellow-billed cacique (Chapman's)" and grouping the other two subspecies as the "yellow-billed cacique (Prevost's)".
