A Christmas armchair untick... :-CAlthough Upucerthia jelskii is considered separate species from U. validirostris in most recent classifications (e.g., Meyer de Schauensee 1970, Ridgely & Tudor 1994), evidence for their treatment as such is weak (Remsen 2003), and perhaps a return to earlier classifications that treated them as conspecific (e.g., Cory & Hellmayr 1925, Peters 1951) is warranted. They form a superspecies (Sibley & Monroe 1990). A report of sympatry in southern Bolivia (Cabot 1990) is based on a misidentification (Remsen 2003). Genetic data (Chesser et al. 2007, Fjeldså et al. 2007) confirm that they are sister taxa but weakly differentiated (Derryberry et al. 2011). Areta and Pearman (2009) found no differences in their voices. proposal needed?
