I have observed a difference in the head of a female & male. I the photograph below the difference is quite clear to me. The male head is more rounded than the female. Looking at a number of pictures on the forum the difference is noticeable on some, but not all. Why that should be I have no idea. Joey, Whiskers and Edward. I'll leave you to decide if there is a difference.  |

Umm, I'm not sure that this would be a definite way to tell sexes, as the skull will continue to grow, same as humans and possibly every animal and therefore every head will have some difference. Some people have a tall forehead, and some not so, some have a long head (front to back) and so on and so on.
I see in younger birds a very shallow head (above the eyes), and in mature birds a very deeper head, if that makes sense. The skull grows to accommodate brain growth. I have not noticed if there is any difference whether it is male or female. When I go down the shed later I will see if there is anything noticeable in my birds, as I have a good age range over both sexes. It is however a good point to raise.
I just Googled skull and brain growth, but it's a bit too complex seeing as I have just finished nights and about to go to bed, I'll never sleep due to thinking about it now OP!

I agree that it's not a definitive way to tell, but yes the females do seem to have differently shapes heads, or it it just the feathers? I have noticed this before myself. The males do display more than females to show off and puff up their little heads  |

I don't know about sexing by head shape of budgies, but when we had our Eastern Rosella, 'George', we were told he was a male, 'cause he had a flat shape to the top of his head, while the females had a rounder, dome shaped head...didn't have it verified, though.
I found this...about half way down it stated, "Males also tend to have a much larger head than the females do, when compared to their respective body sizes."

So, maybe something to this theory ?

Sorry to keep you awake dazandloz. I wasn't meaning to suggest that the shape of the head could be a way of sexing budgies. It's just an observation that in most cases that I have seen there is a different shape. Obviously the feathers are what we see, yet to my inexperienced and failing eyes there is a difference. Thank you for the link Susannah, I will read that some more. It is interesting that the theory had been raised before I had made my observations. I had not heard of it before and was just making it public as to what I had seen. I did see it and it was nothing to do with the intake of single malt.  |

Joey, Whiskers and Edward. I'll leave you to decide if there is a difference. But notice also, OP, that Edward is not standing tall with her feathers flat to her head, either, which I think pronounces the "flat head" look. Her neck feathers are raised somewhat; she is in that relaxed budgie pose. Sometimes Smudge's is quite pronounced like Edward's is there in the photo; other times not so much. And Mango I have never noticed like that at all, but then she is barely still long enough to relax; there is always someone or something to annoy. |
