When threatening a human, these marmosets put their ear tufts forward and fluff up their fur to make themselves look larger. They also make a rapid and continuous vocalization. High-pitched whistle is a warning signal.

In captivity, these marmosets may catch and eat sparrows that fly into their cage.
Specialized short lower canines are used to perforate tree bark, inducing the flow of gums and sap.
