A lovely moment as this female Kestrel flies up to land on an 11kV power pole crossbar. At the time the bird seemed to be about to fly straight through but aerobraked over the pole to 'parachute' down for an elegant landing.

Now all the posts along the bridleway have gone, Kestrels have started using the overhead powerlines as hunting perches - much less effort than all this hovering business! We caught this female as she made a flight along the wire to a new hunting position. We got the whole flight in 40 shots at about 7 per second but she landed unfortunately obscured by a nearer wire. Accurately montaging these 5 taken with Hanslope Church tower as the backdrop (less than half the height of the proposed wind turbine towers and 3 times as far away) gives an impression of the elegant bird.

The female Kestrel moves by at what seems lightening speed (until you see a Sparrowhawk).

The bird flew past us and we caught this view with the Alulae (Alula plural) - the birds 'Thumb' with a few feathers on it - deployed to the same effect as a aeroplanes flaps. Her head was motionless as she hung in the wind, continuously adjusting the angles of her wings and tail. You can see the Grey tail feather quite well here.

The female Kestrel has been hunting intensively over the farm's fields. Here she turns a hover into a dive to the ground, but presumably her prey 'did a runner' and the bird pulls out of her dive.
Unfortunately photographer has already 'lost' her against the hedge and carried on panning downwards to the landing that didn't happen, so losing focus on the bird as she flies away.

Several sightings of Kestrels this week have been mostly whoosh and gone. But this bird is intent on a hunt over the sprouting crop.

The local female Kestrel spent a couple of days intensively hunting around our patch.
Here are 3 images vertically spread of her hovering. She spent about 5 minutes in a hover near the farm entrance oblivious to the traffic, dropping down in steps over what was obviously a 'beak-watering' prey.

An hour later the female Kestrel surprised us by momentarily hovering about 2m above the back 'garden lawn'. The photographer just pointed the camera and 'fired', and was surprised to find even 2 frames with reasonable pics of the kestrel on it. Long-live Auto-focus!

... and rose up for another hunt. All in 2 minutes.

... turned (into the wind of course - she is also know as a 'Wind Hover') and Hovered ...

This female Kestrel took advantage of strong breeze to mix a hovering hunt with standing on posts, railing and tree branches to look for prey. The bird was as usual basically stationary in the air, so we have spread the images top downwards to enjoy multiple moments.

A bit more detail of the hovering Kestrel.

Here hovering in a blustery wind you can see that the female Kestrel's beak tip is motionless against the distant tree despite the movements of her wings and body.

One of the more interesting moments in one of the Kestrel's hovers. Kestrels always face into the wind when they hover and apparently can not hover in still air. A well established common name is the 'Windhover'.

More usually Kestrels around here hunt from perches on the numerous cables and their support posts. But with a decent wind this one follows the traditional behaviour for a 'Windhover' of hanging staggeringly stationary head-on into the breeze using judicious wing flaps and manoeuvring her various flight feathers and tail. She suddenly dived down behind a hedge and, for us, disappeared.

After spending a few minutes hunting from a Black Poplar by the roadside this female Kestrel was hovering to our east facing into biting north wind.

Next day we watched her hunting over the farm crop. She took up a series of hover positions, as always facing into the wind, but the wind was so strong that she hardly ever flapped her wings, keeping station by endless adjustments of the wing angles, tail position and the Alulae (the wing's 'thumbs'). Wonderful to watch such accomplished flight.

The new Female Kestrel doesn't provide any opportunities for hand-held portraits, but she hunts while hovering much more than 'Grey Feather', so here is one of her near the Bridleway to the north, hovering in front of an 11kV cable. The hover starts at the top and this sequence, with a cable a useful vertical reference, and a tower (cropped out) providing horizontal positioning, shows how well the Kestrel keeps station.
Here is a general view of about 1.3 seconds of action ...

... and here more detail of the bird to see the wings and tail in action.

Moving between hovers we get a view of the top of this female kestrel's wings
