Here is my almost 2 year old cockatiel. His name is Pollo and I still don’t know why he keeps making baby sounds when he is around me or when I pet him. Is like a radio trying to catch a channel 😂 he is my velcro bird

I feel like it's supposed to be something related to infinity or some hypothetical number but I can't get any firm results from a precursory image search. I tried drawing what I think the symbol looks zoomed in.

Is it just an 06 or is it something more?
