Would that even work (assuming you mean the bird songs)? I'd imagine bird songs are mostly equivalent to non-verbal singing (e.g. like "la la la") combined with very general information like "I'm here, healthy and single". I really doubt there's anything in bird songs that would constitute language in the sense of verbal expression of information (not to be confused with warning calls, which could as well be specific to certain predators e.g. different calls for "snake", "raptor", or "cat").
