Birds are disappearing.

Birds are nature's essential workers, and they are crucial members of ecosystems around the world. Hummingbirds pollinate our flowers; cardinals munch on beetles, grasshoppers, and other pests that damage crops; owls eat rodents that can spread disease; vultures clean up roadkill and other waste.
Beyond their practical aspects, birds bring us joy through their songs and beauty.

But since 1970, nearly 30 percent of all birds in the United States and Canada have vanished. Scientists are scrambling to figure out what may be causing such a drastic decline. The answer: humans. City lights and tall glass skyscrapers disorient migrating birds. Domesticated cats prowling outdoors kill billions of birds each year. Pesticides contaminate fish and insects, which are then consumed by birds of prey. And climate change might disrupt and even wipe out feeding grounds for entire species.

Discover the vast impacts birds have on ecosystems, food systems, and human communities, and learn more about what scientists are doing to protect them.

Reviews

★ STARRED REVIEW, Kirkus
This pithy book more than fulfills its promise to introduce readers to the importance of birds, the state of avian research, and how they can contribute to birds’ well-being.

The text is both graceful and accessible. It begins with how and why passenger pigeons rapidly became extinct and is unsparing in detailing the deaths of thousands of migratory birds in Philadelphia in October 2020. These sobering accounts are balanced by success stories, such as the rebounding of dwindling raptor populations thanks to wildlife protection laws, a raptor sanctuary, and the ban on DDT. However, along with mentioning how critical birds are to the ecosystem, the text clearly states that 40% of bird species worldwide are shrinking in numbers. There is also a sobering chapter about climate change and its impact on seabirds. A full chapter devoted to the threat posed by domesticated cats uses gentle humor and shows compassion in its recommendations to cat owners. Up-to-date research—including interviews with scientists—highlights the urgency of sustainable farming, bird-friendly skyscrapers, and better placement of wind farms. A cutting-edge discovery by an entomologist, further researched by an urban ecologist, shows how selecting native plants over lawns supports caterpillars, the mainstay diet of most baby birds, turning backyards into habitats. The final chapter exhorts readers to follow the recommendations for reversing the trend toward bird extinctions. The excellent layout, informative sidebars, and attractive images are noteworthy.

Well-informed inspiration.
