While officially listed as least-concern by the International Union for the Conservation of Nature (IUCN), they may, in fact, be at-risk due to human-caused deforestation.

The species is known to locals of the regions it inhabits as a zog-zog or zogue-zogue;[5] however, that name has also been applied to the coppery titi monkey (Plecturocebus cupreus).

[6] Its English common name was selected in honor of Prince Bernhard of the Netherlands, who created the Order of the Golden Ark, an award equivalent to knighthood, presented each year to a group of conservationists.

It was originally described by Marc van Roosmalen et al. in 2002 as Callicebus bernhardi, with the holotype being a complete, mature skeleton, collected in November 1998.

The upper regions of its body and head are grayish black, while on its back, these shades are mixed with brownish agouti or reddish brown.

While individuals huddle together in the night, with tails entwined, this behavior does not correlate to temperature, suggesting it is instead practiced to satisfy social needs.

[11] The Prince Bernhard's titi monkey is of least-concern by the International Union for Conservation of Nature (IUCN).

The organization considered it to not be at risk due to its large range and lack of human impact on its habitat.
