Editing Homosexual behavior in animals (section)

===== Chimpanzees =====
Compared to bonobos, less research has been conducted on same-sex sexual behaviors in chimpanzees (''Pan troglodytes''). In contrast to bonobos, same-sex sexual behaviors are less common in Kibale chimpanzees (''Pan troglodytes schweinfurthii'') and primarily occur between adult males.<ref>{{Cite journal |last1=Sandel |first1=Aaron A. |last2=Reddy |first2=Rachna B. |date=2021-02-02 |title=Sociosexual behaviour in wild chimpanzees occurs in variable contexts and is frequent between same-sex partners |url=https://brill.com/view/journals/beh/158/3-4/article-p249_3.xml |journal=Behaviour |volume=158 |issue=3–4 |pages=249–276 |doi=10.1163/1568539X-bja10062 |s2cid=234056789 |issn=0005-7959|url-access=subscription }}</ref> While less frequent than in female bonobos, same-sex sexual behaviors between male chimpanzees occur regularly and in a variety of contexts. Female chimpanzees are much less likely to engage in same-sex sexual behaviors than males.
