SEA (?) Monkey Skull Head Gear

[asomotif]

Yes David, they look Ifugao-ish.

I found this quote on the web.
Google pictures will provide a lot of recent examples if you search for "ifugao headdress". I enclose one of them :-)

Headdress
Chenevière 1987 p186
"During a special ritual for the anitos, the clan chiefs wear ceremonial headdresses displaying the tusks of wart hogs, symbol of strength and courage, and the beak of the calao, the bird considered to be the messenger of the gods. For coming-of-age ceremonies, monkeys' heads suffice, as the animals are held to be the privileged accomplices of the spirits, who are invoked with laughter and jokes. ... [A]ccording to magic custom, the skull must look in the same direction as the person wearing it."

* Howard 2000 p43
"The feather- and skull-adorned [hats] are ceremonial headdresses."
