Peregrine falcon portrait. (This bird was one of many captive-bred peregrines created to supplement the wild population when it was reduced by DDT usage worldwide. The coral/orange breast color is most saturated in females of the 'anatum' subspecies of the western US. The eastern US population was completely lost to DDT and the population rebuilt by captive bred birds of mixed race, generally not showing such saturated breast color in the females. Breeding peregrines in northern latitudes of Canada and most of Alaska are of the tundrius subspecies, which show consistently white breasts, with some gradation with latitude.) © David A. Ponton
