Longterm Monitoring
Tracking tamarins can be tricky. They are small and fast, and you have to earn their trust while trying to distinguish each near-identical animal from the next. To achieve this, we use an annual mark-recapture program, behavioral observations, tracking technology, and genetics.
By The Numbers
Who are the Tamarins?
Tamarins are primates (family, Callitrichidae) known for their miniature stature and complex, female-dominant social systems.
They have hirsute faces and are very hard to distinguish from each other. No sexual dichromatism is present in the species’ pelage.
They produce twin offspring over 90% of the time. These dizygotic or fraternal twins are more closely related on average due to genetic chimerism

Emperor tamarins (Saguinus imperator), known for their fantastic mustaches, are also fierce creatures, despite their size.
Saddleback tamarins (Leontocebus weddelli) are milder in temperament. They are the most widely ranging tamarin species in the Amazon.
Goeldi’s monkey (Callimico goeldii) is a rare and cryptic primate occasionally observed at our site. They are larger, quieter, and fond of fungus.
Published Findings
We published a protocol on safe mark-recapture techniques for callitrichids. Additional detailed protocols are available upon request.
Our review of sightings of Callimico goeldii in Peru examined data from 340 sites over 40 years to and predict species distribution.
We developed a model to predict the breeding status of individuals based on morphological, reproductive characteristics.
We collated published and unpublished data from 86 studies across 65 localities to assess titi monkey (Callicebinae) terrestriality.
