For an assignment to show a “special view” of a natural process and in this case, I wanted to show an implied lifecycle of Leucochloridium variae as it cycles between two hosts: a black-and-white warbler and amber oval snails #gouache #Sciart
A planted scene featuring two black-and-white warbler on a stump. One warbler has a snail in its beak as the other looks at a soon to be eaten parasitized snail. Healthy snails are at the base eating bird poop.
