Spot the male Bullfinch

I was doing some laundry when I looked out of the window and a flash of red caught my eye. I was wondering if it was a robin or a bullfinch and also if I could make it upstairs to my camera and take a picture from the bedroom window before it flew off. I did get lucky but my zoom is obviously not powerful enough because this is the best I can do for enlarging it. I'm also not completely sure it's a bullfinch.... is it bright red enough?
