Wolf is correct. One should be careful about what name one calls them. I especially dislike it when people adopt a bird from somebody else and immediately change the name because they don't like it. I wouldn't like people changing my name and, in their case, the rehoming alone is so confusing and depressing that I would imagine that losing their name makes things much worse (poor things must feel completely lost!).
But, because I am a stickler for gender appropriate names, I often do change the 'wrong' ones. But I ALWAYS make it a point to choose one that sounds almost identical so Nathan became Naida but I still refer to her as Nate and good boy because she lived 24 years with that and it's what she knows.
Tiamo is a wonderful name! It means I love you in Italian - but it does sound masculine
