Much of the pleasure in photographing these amazing phenomena comes from the chaos. There is no leader and no structure; just a constant triggering of responses from individual birds, rapidly reacting to one another and vying for position.

There are many variables. Birds roost in different areas on different nights. They are spooked by predators and even if conditions are perfect, if you want a photograph you cannot afford to be too far away. The action is fast and short-lived. Once a critical mass is reached, the birds dive for a safe roost and the sky is empty, as if they were never there.

I have photographed at this spot many times; you have an uncluttered view over the reeds, while being close enough to them. The evening sun is behind you, but in the end it is always down to chance.

On this occasion the swirling mass of birds came low and close. For a few seconds they were all around me. It was a unique, exciting and alarming experience - to be inside the flock, to hear the sound and feel the wind-tunnel force of thousands upon thousands of wing beats.

The photographs featured on the web site are a part of an ongoing project. Digital C-types (paper size 35cm x 50cm) are available at £270 including VAT & postage (within the UK) - please email for more information.
