For three years, Jennifer Ackerman lived in the small coastal town of Lewes, Delaware, in the sort of blue-water, white-sand landscape that draws summer crowds up and down the eastern seaboard. Birds by the Shore is a book about discovering the natural life at the ocean’s edge: the habits of shorebirds and seabirds, the movement of sand and water, the wealth of creatures that survive amid storm and surf. Against this landscape’s rhythms, Ackerman revisits her own history–her mother’s death, her father’s illness, and her hopes to have children of her own.
