Living on the Edge is a collection of photographs of black and white birds taken along the Pacific shore of northern California during the winter of 2020. The white birds are great egrets and snowy egrets, the black birds are crows and ravens. These are all common birds, managing along a thin edge of possibility. They are common because they are so adaptable, living along the cliffs at the edge of the ocean, and at the margins of human activity. They are experts at calculating exactly how much energy to spend avoiding close contact with humans.
