Geoffroy's tamarin

Geoffroy's tamarin (Saguinus geoffroyi), also known as the Panamanian, red-crested or rufous-naped tamarin, is a small monkey found in Panama and Colombia. It is mostly black and white with a reddish nape and a chestnut-red tail with a black tip. It is diurnal and spends most of its time in trees, coming down to the ground only occasionally. Groups usually number three to five animals, with a single reproductively active female that mates with several males, and the males contribute significantly to the care of the infants. The diet mixes insects, fruit and plant exudates; insects and fruit make up most of it, while exudates matter when they are easily available. Males average about 486 grams and females about 507 grams, and the species can live up to 13 years. The IUCN classifies it as near threatened.
