chapter one of Pirkei Avot states “And do not engage in excessive conversation with a woman. This is said even regarding one's own wife--how much more so regarding the wife of another.” does this apply to females as well? Or are they allowed to engage in "excessive conversation" with males?
Avot Derav Natan 7:3 describes what this excessive conversation is about. You can read the source, there. In summary, it says that if one was embarrassed by his friend in the Bet Midrash, or he had a confrontation with his friend, there, he should not mention the details of it to his wife, because his wife will make fun of him, and he will lose his respect from his wife.
Since women are unlikely to study in the Bet Midrash, it would seem that the Mishna mentions this prohibition regarding men talking excessively with women.
However, if you were to follow a more general adage from Avot 1:17, Shimon ben Gamliel says that the best thing for the body is silence. That Mishnah is not specific to men but applies to everyone.
I'm going to follow his suggestion by stating, "Enough said."
