A Tree Swallow in flight as seen in a profile view which reveals the beautiful delicate detail of the birds wings and tail feathers. Tree Swallows are fast flying, acrobatic birds typically seen chasing insects over wetlands. I captured this image at using a Nikon D7100 with a AF-S Nikkor F4 lens at a shutter speed of 1/4000 second, aperture f4, ISO 450, at a focal length of 300mm. Capturing this beauty in flight was an exercise in patience and I have yet to capture a similar image of a swallow in flight. Photographed in Spring at Burnaby Lake, Burnaby, B.C.
