It was a spring day on the Crouch, the River Crouch in South Woodham Ferrers. At this time it was high tide. These images were captured on two days.
Black headed Gulls
On the first day I had taken some bread with me and sat on a bench. It was tricky to both throw the bread and then capture images of the black headed gulls as they piled in after the bread. I needed a second person with me for throwing. Nevertheless, good images were captured as the noisy varmints wheeled and turned before they dived for the bread.

Firstly, there is the image of three gulls ready pounce on the bread that has just been thrown. They have no regard or anyone else and that includes the much larger swans. Unlike the gulls, the swans sit patiently like battleships in the water waiting for the bread and let the gulls scavenge around them. The second image shows a gull flying past with its head turned 90 degrees, looking right at the camera. Alternatively, its looking for more bread! Nonetheless the image captures the gull as if it is stationery in mid air. In the third image a gull is concentrating on its target as it descends.
Swans
Swans are so majestic. Image four shows a swan which may be asleep as it floats by. A close look reveals a beady eye watching the bank though. Image five shows a swan propelling itself along with one of its feet in the air. Several swans were doing this, however it looks like a contortion to me. The sixth image shows these creatures in full regal majesty making there way across the water. In contrast to the others, image seven shows two swans on the shore billing and cooing.
Returning to the water, image eight clearly shows that one of the swans has disturbed the water as it makes a 90 degree turn while its mate carries straight on.
Panning
Moving on, the two final images are captured at Clementsgreen Creek and use the panning technique on another a spring day on the Crouch. Essentially, the camera moves with the subject. This allows the subject to be frozen clearly in the shot as the background is blurred as the camera speeds past it.
