From Kenn's Drawing Table: Work in progress: Red-legged Cormorant.
There are about 40 species of cormorants in the world. They occur on all seven continents but they're widely dispersed, usually with no more than four species at any one locality, so it would take a lot of traveling to see them all.
By now I've seen most of them; my favorite is Red-legged Cormorant, a specialty of western South America (Peru and Chile), with a few also in southern Argentina. I had seen these birds on past trips, but when we watched them in Peru last winter, I knew I'd have to try painting them. The pattern of whitish spots on the upperparts is unique in the family, while the circle of sky-blue dots around each eye is another intriguing feature.
