SOLVED. Memoir-type about chimps adult author works in park and describes about 8 chimps' lives [s]

[Elisheva Rina]

He writes about working in a reservation/park while working towards his degree. The park has several "islands" separated by water. He is fascinated by the complicated lives and families of the chimpanzees. The chapters are mainly based on one chimp and he goes into the life stories of possibly 8, maybe 6 of them. One thing he feels strongly about is that apes have fascinating family structures and a "culture" of their own, and teaching them English is nonsense (he hates Koko's teacher). Fascinating book, I really liked it. Possibly published in early 2000's.

This is probably too recent... The Song of the Ape: Understanding the Languages of Chimpanzees by Andrew R. Halloran?

That's it! Thank you, thank you! (I was totally guessing about the year it was published.)

You're welcome.
