This image, initially, looks pretty wierd to people.
On first impression many people think the owl is flying upside down, but then they see the mouse in its talons below.
The owl is flying in level flight with its head rotated 180º looking upwards towards the sky - Not a typical flight posture as most avian predators rarely have to be concerned with attack from above themselves by another predator - falcons notwithstanding
But wait, what is that shadow on its face?
It is a northern harrier's shadow, flying above, which is strongly contesting ownership of the mouse.
Like with canines, you really don't own food until you have swallowed it.
This frame was one of many, shot in a sequence of High Frame Rate images, as the owl and the harrier went at mortal combat in aerial flight -
The owl eventually dropped the mouse, and both the owl and the harrier went hungry for a bit longer. I think the owl was at a disadvantage with one set of talons holding a mouse and hence unable to be used to defend against the harrier.
The talons of an owl, or a harrier, would pass right through the palm of your hand and stick out the top, like passing through hot butter. I have seen many mice and voles impaled on the talons of owls - it is no contest.
