Need ID Help – Peru – squirrel and squirrel monkeys

Hi,

In Tapiche both the squirrels and squirrel monkeys were sometimes rather confusing:

1. Squirrels

Attached is a slightly out of focus picture of a Sciurus squirrel.

To me the hairs on the feet appear almost all red, but the hindlegs clearly show some black – does the black at the nail tips make this a Southern Amazon Red Squirrel? I think so, but not sure.

The two photos are identical, but the second has been overexposed three stops.

2. Squirrel Monkeys

The Handbook of the Mammals of the World 3 states that Ecuadorian Squirrel Monkey (macrodon) and the peruviensis form of Black-capped Squirrel Monkey both occur and intergrade in Tapiche (they specifically mention Rio Tapiche and Rio Blanco).

Some of the Squirrel Monkeys seemed to be pure peruviensis with a proper dark blackish cap, but the monkeys in these photos appear to be intergrades or even Ecuadorian Squirrel Monkeys. Can anyone comment?

Photo 1 (the “relaxing” animal) is from a different group than the other ones, which were all in the same group. One photo of three group of  3 was overexposed 2 stops in Photoshop for clarity.

Cheers,

Sjef

    Sjef,
    I wouldn’t use HMW as a source on primate taxonomy. The most recent study has found that there are only 2-3 species of squirrel monkeys: http://link.springer.com/article/10.1007/s10329-014-0452-0
