White-Headed Marmoset Characteristics

White Headed Marmoset

The Geoffroy’s marmoset[1], also called Geoffrey’s marmoset, white-headed marmoset, or tufted-ear marmoset is a marmoset native to the forests of eastern Brazil, where it is native to Minas Gerais, Espírito Santo, and Bahia.

  • Geoffroy’s marmosets are small primates, only around 20 cm long, with a tail of around 29 cm.
  • Females typically weigh around 190 grams, while males weigh between 230 and 350 grams.
  • The body is usually blackish or dark brown. The tail is surrounded by black and gray bands.
  • Adults have white foreheads, temples, cheeks, and throats. Also, adults have black tufts of hair in front of their ears.
  • Juveniles differ from adults because they lack both ear tufts and white markings on the face.
  • Instead, juveniles grow their ear tufts at around two weeks and have full adult markings by five months.

White-Headed Marmoset Facts

Callithrix Geoffroyi

  • The dominant female and male in each group of Geoffroy’s marmosets form a monogamous pair. Therefore, only this pair will reproduce.
  • Pre-copulatory courtship typically begins with sniffing each other’s genitals and object marking, grooming, licking, and cuddling.
  • Geoffroy’s marmosets are said to follow swarms of army ants to catch insects expelled by the ants.
  • They send out alarm calls when they sense a threat. Also, they have observed scent marking.
  • Groups of Geoffroy’s marmosets respond to predator threats by increasing vigilance rates and decreasing rates of foraging and play.
