Looks like a male to me.
His diet is in need of improvement, in my opinion. If you have been feeding this bird this diet for four years and other diets of a similar type then I would suggest that you have a comprehensive blood panel with a bile acids test done to rule out liver disease. The bile acids test is expensive but it is the only test that can detect liver disease before liver failure is imminent.
I am always afraid of dried fruits and so I never use them for my birds, I give them fresh fruits instead. I also give them both fresh, raw vegetables and cooked vegetables daily. The cooked vegetables are part of a cooked food that is the base of their diets. This food consists of 40% cooked whole grains, 40% cooked mixed vegetables and 20% cooked white beans and lentils. I then feed a seed mix similar to the one you describe for their dinner, but I remove it when my birds go to sleep at night. The cooked foods and fresh vegetables, fruit and a fresh leafy green are given for breakfast and left for them to nibble on all day.
I feed my birds in this manner because all of the seed mixes or pellets are too high in protein and many of them contain soy and other substances that I feel are bad for my birds.
