* Two notes:
I myself like to use the word “who” to refer to animals and birds, but I’m in a minority.
American editors, teachers, and presumably professors strongly prefer the word “that” in restrictive clauses, to the point that many consider “which” an error. I disagree, but I’m in a minority. My advice: use that for restrictive clauses and which for nonrestrictive.
