Quaker parrot sexual behavior
I have a three year old Quaker named Rocky. We assumed it was a male but the behavior lately leads me to believe it's a female. I know the only way to find out the sex of the bird is to have it tested at the vet, but it's not that important to me to know for sure, I was just curious.
Rocky has had a Happy Hut in the cage for the past year and has done nothing to it but lean against it once in a while. In the past week Rocky has taken to sleeping in the Happy Hut and is quite protective of it. Yesterday he was on a perch and began making loud breathing sounds and moving in slow motion, (almost like Tae Kwon Do) and started lifting the tail and rubbing his bum on the Happy Hut.
He/she also has an obsession with flatware spoons, often stealing them and arranging and hanging them on the cage like abstract art. I attribute the sudden love of the Happy Hut to a nesting instinct leading me to believe Rocky is female. What other behaviors do the birds have that distinguish between male and female or do both sexes act the same? Or do I just have a weirdo for a bird?
