U.S. Geological Survey Marine Ecologist Dr. Caroline Rogers recently captured these two kestrels, known locally as killy-killy, perched just outside her office window at Lind Point. Rogers even observed one of the birds, known in the states as sparrow hawks, enjoying a lizard snack. The female kestrel, top, is a bit bigger than the male, bottom, and has black spots on a light breast. In addition to lizards, kestrels eat mice. We spend so much time talking about things that are endangered, but these birds are still quite common and doing well, said Rogers.
