| Abstract: | Researchers have long considered the color of female sexual skin to play a role in attracting or inciting competition among
males, or both; however, females may also use color in intrasexual communication. To assess this possibility, we examined
whether variation in same-sex sexual skin color is salient to female rhesus macaques (Macaca mulatta). We exposed adult females to computerized images of conspecific female faces and hindquarters manipulated for color (red
vs. non-red), within the natural range of color variation. Females visually attended more to both reddened faces and hindquarters
over the non-red counterparts. We conclude that female color might be biologically meaningful to other females. |
