Alarmingly few Swifts, Swallows and Martin so far this year.
Here is a passing Swift.

More Swifts (again shown with the 10 body length between images reduced to very little) showing the variety of wing positions in normal flight. These images are about 0.2 seconds apart

A close spaced montage at about 10 fps.

Swifts fly fast - this montage is accurately spaced (based on the tree) at about 0.1 second intervals.

We are trying to catch the moment of an insect about to go into a flycatchers beak. During this attempt we got this unusual sequence of what we think is a swallow reaching way up to catch an insect. Probably about 200mS between images with arbitrary positions.
We guess that the insect was hidden by the right wing of the first image, and inside the beak by the second!

Swifts really fly fast - this and the next sequence are photographed at about 10 fps (Frames per second). That's about 100 body lengths per second!
The detail of the bird is lost at any size of image that it is sensible to email or put on the WWW, which is why we mostly provide 'Close spaced Montages' to get a better view of the creature.

Swifts are normally photographed as sickle shapes, but they have a full range of wing movements, here caught near the top of its wing stroke.

A Swift catching an insect - beak open next to last image from the left and the tiny speck of life it consumed is just in front of the open beak. These at about 7fps so slightly less than 1 second of action here.

The swifts have been mostly flying very high but have occasionally come low enough to be much better than 'specks in the sky'. With naked eye they tend to appear as black silhouettes but a camera with exposure locked to prevent the sky forcing underexposure it can show the subtle grey markings.

Some swifts did a few low circles. Here one has it's mouth open to catch the insects it feeds on.

No this isn't turned sideways!
The swift was sweeping up to catch an insect (not big enough to spot even in the original).

We often hear that Swifts spend their entire lives in flight expect when breeding, and even then have to choose high places where they can 'drop down' from to gain flight speed.
We understand that a Swift on the ground can not take off without help.
We had never really thought about what constant flight means, but it must include still having to maintain your feathers. Here over about 2 seconds the bird twists to access one of it's flight feathers, and drops a good distance in the process.

All three of our 'regular' owls making landing on the meadow post.
The sizes of the Owl images are all at the same scale.

A Visit by what we think of as the 'local' Tawny owl.
After the landing (left) we get a illustration of the rotation of an Owls neck - 270 degrees from multiple sources (all possibly referencing the same original). While this sounds like the bird can almost 'look behind' it, it is actually (360-270) / 2 = 45 degrees short of completely backwards each way. The eyes are so big they can barely move them in their sockets', so to remove the 'blind spot' compare the middle and right images to see that this Owl also twists it's body to increase the amount of turn.

On the second visit of the night, this Tawny Owl makes a really rather awkward landing on the post. This is the only image from the second visit, and the bird may have flown on to perch on one of the many other posts and branches that 'he' uses.

A Tawny Owl has restarted regular visits, sometimes a few days between visits and sometimes 3 a night! Unpredictability is the watchword of opportunistic hunters. Here the Tawny Owl gives us a spectacular landing with eyes firmly shut.

The less regular Tawny Owl (the individual with the blue-grey eyelids and moustache) at his preferred choice of perch at the kitchen window.
The Owl broke the trigger beam on landing, folded the wings that allowed the camera to reset, and then triggered the camera again when opening wings to drop down. Rodents occupy the 'ground floor' between this perch and the house and expect that one of them became the bird's next meal. The bottom of the leaving bird was out of frame at the bottom of the original image, so this construct is the best we can do.

The Tawny Owl visits the perch at the kitchen window. The wings are partly folded as the Owl lands.

One of two Tawny Owl visits to the kitchen window perch 13 minutes apart.
