Where Have All the Birds Gone?: Nature in Crisis

This nonfiction account examines the decline of bird populations and the many threats birds face, including cats, wind turbines, glass windows, shrinking food supplies, habitat loss, and light pollution that disrupts migration. It discusses a 2019 study reporting that three billion birds, or 30 percent of bird populations, had disappeared since 1970. Chapters explore particular dangers, stories of loss, and some successful recoveries. The book also explains birds’ roles in ecosystems, such as pollination, pest control, rodent control, and cleaning waste, and considers actions people can take.
