A sparrow. I thought for a split second someone had thrown a stone at our kitchen window! But it was a sparrow flying into it. It's still conscious but hasn't moved for several minutes, just sitting in the garden. I can see it blinking and moving its tail a little. Hopefully it will recover and fly away (maybe even before one of the neighbourhood cats finds it). But maybe it's got an internal injury and will bleed to death in the garden. Ah, it's moving its head all round now, so seems to be on the mend.
