None of my males know how to wolf whistle, but they are great singers, they can learn if I either whistle it to them or play videos on YouTube to them (I don't know how to whistle so that gives me one option)
I am currently teaching my birds how to sing happy and you know it
But as stated above, not all males whistle
Mine came home from the Bird Farm knowing it (when we bought him). I assumed the employees taught him. He hasn't done it in ages though. "Whistle While You Work" is his favorite although I'm trying to teach him other songs.
I just read somwhere that males wolf whistle so I thought it was a natural call and It was just coincidence that it sounds like what humans do .
anyway our tiel (pikachu) original I know lol ! , does wolf whistle when we walk in or just randomly and is really noisy when gets goin ha , it's around 17week old so I'm guessing there's a good chance it's a boy .
we've only had him 9 days or so .
I've taught him to handshake with millet spray , although he's not keen on being stroked .
anyway it sounds like Tiels are not known for mimicing human speech rather just whistleing tunes .
we had a budgie what knew 100s of words and sentences and we found him on street lol
