Would the vulture crown have been worn by male pharaohs? In all the images i've seen, it was worn by queens like Nefertiti, Hatshepsut and Cleopatra

Nefertiti

blue crown and vulture crown

In wartime the pharaoh wore a special blue crown. Here's an image of King Tut fighting the barbarians

Originally posted by Nick1986 As you said, the crown of Upper Egypt (in the south) bore a cobra. In Lower Egypt (in the north) the king's insignia was the vulture (see the above photo of Tutankhamen who wears both to demonstrate his mastery over all Egypt)

Am I right?
You said; Upper Egypt/South = Cobra and Lower Egypt/North = vulture

I guess, it should be opposite.

Cobra symbolizes delta of Nile so Lower Egypt is Cobra  (Wadjet)
Vulture is a desert animal, Upper Egypt                       (Nekhbet)

Vulture
In Egyptian mythology, Nekhbet (also spelt Nechbet, and Nekhebit) was an early predynastic local goddess who was the patron of the city of Nekheb, her name meaning of Nekheb. Ultimately, she became the patron of Upper Egypt

Cobra
Wadjet was claimed as the patron goddess and protector of the whole of Lower Egypt

reference:viki

In Lower Egypt(they called it Upper and themselves Uppers)we have snake cobra in crown.What did present crown of Upper Egypt?

Egyptian pharaohs had several distinct crowns. The first of these, the Nemes Headdress, was worn everyday and comprised a striped headscarf and a circlet bearing the vulture and serpent of Upper and Lower Egypt.
