The natural history of Atlapetes pallidiceps has been studied in some detail by Krabbe and coworkers (Agreda et al. 1999, Krabbe 2004) and Oppel and coworkers (Oppel et al. 2004a,b), but far the most data has been collected by Mery Juiña with various assistants and coworkers (including Harold Greeney) from 2002 until present. Her results are expected to be published in 2008, and
a summary will later appear in this section.
