Wings over water.

The new Weekly Prompt Photo Challenge is Wings.

I thought about swarms of insects but decided that while you can see the insects you can’t see their wings while they’re flying in the swarm.

Then I thought about some of the photos from when I was a member of a small group of birders surveying and recording a winter roost of Gull species on an inland reservoir in south Cheshire, England.

This week’s Cosmic Photo Challenge is Bodies at rest/Bodies in motion.

My first thought was a flock of birds taking flight. That should be easy as I have lots of flocks of birds in my files. Well it didn’t quite work out as easy as I thought it would be. For example, every photo of Snow Geese taking flight I checked has all the birds in motion. I checked some of the wader (shorebirds) species I have on file. Most of those photos either had all the birds at rest or all the birds in motion.

Then I remembered some of the photos from when I was part of a small group surveying and recording an inland Gull roost on Hurleston Reservoir in south Cheshire. The photo below shows a section of the Black-headed Gulls moving to a different part of the reservoir with other birds staying in place on the water.

The Weekly Photo Challenge is Prolific.

For several years in the 1990s I was part of a small group surveying and recording an inland Gull roost on a reservoir in Cheshire, England. Numbers peaked in the winter although there was birds there every month.

The majority of the birds were Black-headed Gulls. Typical numbers were between 13,000 and 22,000 Black-headed Gulls in the winter.

The photo shows part of the roost in the process of moving to a different section of the reservoir.
