I meant to post these earlier, but I kind of got sucked into other things and eventually forgot. You know how it is.
The sunlight was not being cooperative with me just at this moment, so it was challenging to get any decent pictures of this particular monkey. How so?

Well, with this stupid fence mesh in the way, for a start. With a glossy finish on it, no less. Some people just have no respect for the struggling photographer, let me tell you.

Male and female white faced sakis are dimorphic. The females are all black, or possibly all grey depending on how you want to look at them. Only the males have their namesake white faces. Misogyny again, even with monkeys. What a crock.
Anyway, the unavoidable polka dot effect created by the fence here might just serve as a small but fitting unintentional tribute to Yayoi Kusama, and almost even on time.
