Male or female?
My Flickr photos...
Male due to extent of red on head and black nasal bristles. Also dark wings.
Looks like it, on the amount of red behind the eye.
For non-ringers, females tend to have the red above the eye with a concave edge, where in a male it tends to be convex, as in this bird, extending beyond the rear edge of the eye. Not always reliable, but usually works.
Nasal hairs (male=black, female=grey-black) I have problems with...it takes a really close view and I am poor at colours. Well done to anyone who can sex a Goldfinch in the field on nasal hair colour!!
The reference to dark wings is the lesser coverts on the shoulder, which are black in a male and brown edged in a female. They are rarely visible on a perched bird, however.
