What's the female/male ratio for Chimpanzees and Bonobos? Is
this even known?

Research stations and breeding programs would produce a record
of births plus what is living at any one point and their age.
The Gombe people would know but I think its pretty much what
you find in humans. You get odd things with the Big G.

Actually, for humans it varies by location between 0.86
male/female births in the Cayman Islands to 1.14 male/female
births in Guam. Most places are around 1.05, but it's lower
in southern places, on most island locations and in the
southern hemisphere; and is slowly decreasing in
industrialized nations.

The adult ratio is apparently heavily skewed in the female
direction for chimps because of all the fighting that goes on.
What the ratio is at birth, however, is a different question.
