I spent an evening on the Bow River at the Inglewood Bird Sanctuary on the weekend. It was a beautiful day, warmly lit in golden light, and I had a great time photographing the birds well into dusk. Among the birds nearby were a few Double-crested cormorants fishing and flying around. I photographed as they flew or swam by. They are exceptionally fast birds and they often fly just above the water at speed which is exciting to watch. After the sunlight had left the river, I caught sight of one of these cormorants moving upriver. Darkness was starting to settle in so I dragged my shutter in order to use the lack of light to pan with the bird as it passed me. I used a shutter speed of 1/40th of a second and it worked out pretty well.
