'''Geoffroy's tamarin''' ('''''Saguinus geoffroyi'''''), also known as the '''Panamanian''', '''red-crested''' or '''rufous-naped tamarin''', is a [[tamarin]], a type of small monkey, found in [[Panama]] and [[Colombia]].  It is predominantly black and white, with a reddish [[nape]].  [[Diurnality|Diurnal]], Geoffroy's tamarin spends most of its time in trees, but does come down to the ground occasionally.  It lives in groups that most often number between three and five individuals, and generally include one or more adults of each sex.  It eats a variety of foods, including insects, [[Exudate#Plant exudates|plant exudates]], fruits and other plant parts.  Insects and fruits account for the majority of its diet, but exudates are also important.  But since its teeth are not adapted for gouging trees to get to the sap, it can only eat exudates when they are easily available.

Although a variety of reproductive methods are used, the most common is for a single adult female in the group to be reproductively active and to mate with multiple adult males in the group.  After a [[gestation]] period of about 145 days, she gives birth to either a single infant or twins.  Males contribute significantly to care of the infants.  Sexual maturity is reached at about 2 years, and it can live up to 13 years.  Geoffroy's tamarin is classified as being "near threatened" by the [[International Union for Conservation of Nature|IUCN]].
