Susan Cerulean's memoir trains a naturalist's eye and a daughter's heart on the lingering death of a beloved parent from dementia. At the same time, the book explores an activist's lifelong search to be of service to the embattled natural world. During the years she cared for her father, Cerulean also volunteered as a steward of wild shorebirds along the Florida coast. Her territory was a tiny island just south of the Apalachicola bridge where she located and protected nesting shorebirds, including least terns and American oystercatchers. I Have Been Assigned the Single Bird weaves together intimate facets of adult caregiving and the consolation of nature, detailing Cerulean's experiences of tending to both.
The natural world is the "sustaining body" into which we are born. In similar ways, we face not only a crisis in numbers of people diagnosed with dementia but also the crisis of the human-caused degradation of the planet itself, a type of cultural dementia. With I Have Been Assigned the Single Bird, Cerulean reminds us of the loving, necessary toil of tending to one place, one bird, one being at a time.
