Ok I was just wondering because the cere seems not fully coloured. It's pretty difficult to say from their behaviour that they are male of female (apart from their obvious sexual behaviour when they are adult, but then the cere is fully coloured too).. Is she still young? My males like to tear things up as well! And my oldest male likes to throw things of the table, such as thee spoons and a small match-box XDD little rascals..
Oh, no, we've had her for several years now. She's really amazingly healthy for an English. The only other two we've had were both not nearly as athletic. Her cere also has gotten more pale over time, admittedly.
Hehe her eyes are hidden below tiny feathers, making her very narrow-eyed (looks a bit stern, don't you think?). One of my budgies (King George) has that too, but not as extreme as your Winter. The salesman said that King George comes from a line of English budgies, although I highly doubt that (he is just as small as my other 2 budgies). But it gave us inspiration to give him a noble English name
