Really, Tamborine? I wonder what the bloody great monstrosity is that’s usually taking their sparrows then, I was lead to believe that was a sparrowhawk? Saw it take a dove last year too, much bigger than this thing but didn’t have the camera to hand? It turns up periodically for a couple of days then disappears for ages?
I'll try and get a pic next time!!
My answer related to the second bird described by the OP as he implies the bird is much bigger than would be expected in a female, be interested to see photos of that one... if the size difference is less significant I would agree a pair of sparrowhawks
