by running towards the calling marmoset, while expressing vocalizations of excitement. The dominant female will sometimes also express these vocalizations of excitement. If the food is not given, the female and younger marmosets will stay near the adult buffy-headed marmoset while conveying short vocalizations, to display their presence and express a need for food. Diet The buffy-headed marmoset is known primarily for eating fruits, gum, and plant exudates. A small portion of their diet is composed of bird eggs and nestlings. While most marmosets are known for being gumnivorous, the buffy-headed marmoset is predominantly mycophagous-insectivorous. Additionally, they may prey on both vertebrates and invertebrates: primarily orthopterans, phasmids, coleopterans, caterpillars, and tree frogs. Fungi Often found at the base of bamboo, fungi are also known to be included in the diet of buffy-headed-marmosets. Because this group of marmosets primarily inhabits areas in which fungi are abundant, it tends to be a consistent source of sustenance throughout the year. Fruits and exudates vary seasonally, and thus are not as readily available, nor as frequently consumed. Fungi, when present, are typically preferred by the buffy-headed marmosets, and likely more nutritious by comparison to their other dietary components.
