\begin{abstract}
Allopreening occurs in many species of birds and is known for providing
hygienic and social benefits. While this behavior has been studied
between conspecifics, its occurrence among different species remains
mysterious. Outside of captive environment, only a few records of
interspecific allopreening exist. In this study, we describe our
observations of Spot-necked Babbler (\emph{Stachyris strialata})
preening Nonggang Babbler (\emph{Stachyris nonggangensis}) in a
non-captive environment in southern China. We provide three hypotheses
(social dominance, cleaning mutualism, and hybridization) to explain the
occurrence of this understudied behavior. We suggest that interspecific
allopreening may not be as rare as we thought if we study this behavior
under circumstances where it most frequently occurs. This study
contributes to our understanding of not only the potential mechanism(s)
for interspecific allopreening but also the behavioral ecology of the
vulnerable Nonggang Babbler.%
