Mantled howler monkey(rare lack of melanin)

Normally mantled howler monkeys are all black, with a touch of reddish toning on the shoulder. Due to inbreeding of this troop, Goldy(and a sister before her) are an all over gold-red with pale face and feet/hands(which differentiates her from A, palliata palliata, and A seniculus). She has been unable to carry an infant to term. We had been told that they hadn't seen her for several months and were hoping she was still with her adoptive troop - having been kicked out of a previous troop. I never could get a photo of her with other members of the troop. I also found that I was able to get more pictures of her that were clear than with regular howlers
