Is it a male?

[ceegull]

My GCC lifts its wings and spreads them abit and makes itself bigger by 'standing' up when playing or getting angry. I read somewhere this is male behaviour. Does anyone have a female that does this? Or does anyone know it to be true? My sun conure does not do this at all it just extends its neck out to attack. I will soon do a DNA to find out but I am real curious if this behaviour is a giveaway.

My conure is DNA sexed as female and does this. Easiest way to know is just simply get the test done - costs $25 from companies like Biotech (if I recall properly)!!
