The "cycle of violence" hypothesis implicates child abuse
as a cause of later violent behavior via social transmission between
generations. It has received mixed support from human research and has
prompted the study of nonhuman models with comparable abuse behaviors.
The underlying biology of child abuse remains a controversial subject,
perhaps partly because, in nonhuman animals, similar behavior occurs
relatively rarely in wild populations. The nazca booby (Sula granti), a
colonial seabird, provides a nonhuman model in which maltreatment of
nonfamilial young is widespread under normal living conditions.
Essentially all adults show social attraction at some point in their
lives to the offspring of other parents, often with a sexual and/or
aggressive motivation. Here, we show a correlation between the degree to
which a young bird is targeted by such adults and its own infliction of
maltreatment later in life. The results provide the first evidence from
a nonhuman of socially transmitted maltreatment directed toward
unrelated young in the wild.
