Osprey chasing Turkey Vulture. Flamingo Marina, Everglades National Park, Florida.
Action photography is always something I have been drawn to, and particularly raptors in flight. The Everglades National Park is really Osprey heaven. There are roughly 20-25 pairs of Ospreys in the Flamingo area, and many have their nests close to the shoreline, for ready access to the abundance of Florida Bay. Ospreys are remarkable in many ways; one fortunately is that for a large raptor, they are remarkably tolerant of humans. Vultures are another story, however, and the ever present vultures eventually annoy either of the nesting osprey parents into a chase. The vultures often appear to deliberately provoke the ospreys by gliding within a few feet of the nest, and then just take off with the angry osprey parent close behind. Unlike other smaller raptors, I have never seen an osprey actually strike a vulture with deadly intent in their mid air combat displays. Like most images involving a chase, it is difficult to have both animals in focus at the same time, particularly with the narrow depth of field available when using a long telephoto lens and teleconverter. Another problem is on which of the birds do you hold the AF sensor to achieve the maximum sharpness? One trick I have learned is to use the AF stop buttons on the lens and camera back – particularly when the birds are flying parallel to me. As they are not rapidly moving out of the zone of sharpness; once the AF has locked on, I use the AF stop button to hold the focus, then recompose as I am panning (to ensure both birds are in the frame) and then release the shutter. After a single frame or a short burst – I then engage the AF again, and repeat the process if there is still an opportunity.
