The thing about parrots...

Parrots have different relationships in the wild. They generally form very close relationship bonds that are far deeper than our own. Parrots are strictly monogamous. Rarely, some “reshuffling” happens, if they find that their current relationship doesn’t “yield” any young. If they lose their partner for whatever reason (death, capturing, etc.), they will also seek another mate. (via Understanding Parrots: Why Parrots Do What They Do)
