Like the canary in the coal mine, "[b]irds in the wild function as a roaming, natural detection system" for environmental pollution and may themselves spread potentially dangerous viruses, writes Nobel laureate Doherty.

The author, an enthusiastic bird-watcher, combines bird lore and cutting-edge science in an attractive mix that should inspire citizen scientists to pursue their hobby with renewed vigor and convince others to join in.--Kirkus
