摘要: The predator avoidance behaviour of a free-ranging group buffy-headed marmosets,Callithrix flaviceps, was recorded in detail during the course long-term study behavioural ecology at Fazenda Montes Claros, southeastern Brazil. Four distinct patterns behaviour, each with specific vocalisations, were recognised and are described here. selection use sleeping sites by also described.
