Why was "which" selected, not "who"?

[Ov28]

Nice to meet you! This is my first post. This article from Wikipedia.

An azmari is an Ethiopian singer-musician, comparable to the European bard. Azmari, which may be either male or female, are skilled at singing extemporized verses,...

I can't understand the reason why "which" is selected here, not "who", though azmari are people. Would you clear it up? Thanks in advance.

Welcome to the forums.

Because it is the word "azmari" that is referred to, not a person.

I'd still say "who" in this context. Azmari refers to people.
While I love Wikipedia, and use it a lot for an overview of a subject, I have to point out that it's written by amateurs, and the English is not always perfect.

Best wishes for 2008

I also would have used "who" in that sentence.
