Elkpen (aka Christian Kasperkovitz) is a street artist based in Los Angeles, California whose work contemplates the effect of urban life on familiar, threatened or extinct flora and fauna. In 2014, she was commissioned to create the design on the exterior of the Los Angeles River Rover, a mobile classroom which is used to teach students about the significance of the Los Angeles River to wildlife in the city.
Elkpen's work has been seen on buildings, busses, beaches, fences, light poles and bus benches in the US and Canada.
Elkpen's work uses both images and words to convey biological, historical, and environmental information to draw the viewer's attention to the wild life or lack of wild life in a particular location.
Elkpen's subjects have included cottonwood trees, alder trees, coastal prairies, Grizzlies, Giant Swallowtail and Anise Swallowtail butterflies, Fairy Shrimp, Western Kingbirds, Goldfinches, Northern Mockingbirds, Yellow Chevroned Parakeets, Black Phoebes, Woodpeckers, Crows, Bushtits and many other birds found in Southern California.
