Male or Female Sparrowhawk ?

I've been getting quite a few visits from Sparrowhawks recently.

This one I've shown before and is definitely a male.

This one which I've also posted before is, I'm sure, a female.

This one has just visited. I only managed to get a brief view before it flew off with its prey.

Initially, I thought the head looked like a male but there's no rufous cheek and the back looks brown and rather mottled. It also looks quite large so  I'm now veering towards it being a female. What do you think, male or female?
