In the raptor world, the larger female rules the roost. In this case, the male merlin was minding its own business, when the female flew in and chased it off its perch. The female took off shortly afterwards. In a world with limited food supply, competition can be fierce. I photographed this image with a Canon EOS 7D Mark II, Canon EF 500mm f4L, Canon 1.4x extender, f/5.6, 1/3200 second, 500 ISO.
