Heads up: Some or all of the identifications affected by this split may have been replaced with identifications of Furnarius. This happens when we can't automatically assign an identification to one of the output taxa. Review identifications of Furnarius leucopus 11281

Taxonomic Split 133965 (Committed on 05-11-2023)

Pacific Hornero Furnarius cinnamomeus and Caribbean Hornero F. longirostris are split from Pale-legged Hornero F. leucopus (Clements 2007:270)

Summary: The Pacific Hornero mainly of coastal Ecuador and northern Peru and the Caribbean Hornero of northern Colombia and Venezuela are split from the Amazonian Pale-legged Hornero.

Details: Most currently recognized taxa of the Furnarius leucopus complex (e.g., Peters 1951) were originally described as full species, and F. cinnamomeus continued to be treated as specifically distinct by Chapman (1926). Numerous more recent authors (e.g., Ridgely and Tudor 1994) have suggested or enacted splits. Differences in morphology that are largely congruent with apparent vocal (Boesman 2016 [No. 88]) and genetic divergence and paraphyly (Harvey et al. 2020) led WGAC and Clements et al. (2023) to agree with Aleixo et al. (2013), Donegan et al. (2013), del Hoyo and Collar (2016), and Gill and Wright (2006, IOC v.1.0) in enacting a three-way split. Further study is needed in the complex, as suggested by the apparently deep genetic split between Guianan and western Amazonian populations. A 2003 SACC proposal (https://www.museum.lsu.edu/~Remsen/SACCprop35.htm) did not pass pending published data.

English names: The geographically based English names for the daughter taxa align with HBW and BirdLife International (2022), Gill and Wright (2006, IOC v.1.0), and other sources.
