Female as she is brown rather than black and does not have the orange beak
It's a juvenile, which are all brown. When they moult, as this bird is just starting to do, the new feathers coming through reveal the sex. You can sex them on tail colour before that, but that is not easy here because of the angle. However, the few feathers coming through on the wing seem to be black, so it is probably a male. The yellow beak does not come until the next summer...young males have a mostly dark beak in their first winter.
