THE BIRD WAY

The author of The Genius of Birds returns with an exploration of “surprising and sometimes alarming behavior” of everyday avian activity.

Science journalist Ackerman showcases various aspects of typical bird activity—communicating, working, playing, parenting—that have been “dismissed as anomalies or set aside as abiding mysteries.” In reexamining these behaviors, scientists have been able to identify “remarkable strategies and intelligence underlying these activities, abilities we once considered uniquely our own,” including deception, kidnapping, infanticide, cooperation, collaboration, altruism, and culture. Extreme behavior reveals insights and new perspectives on birds’ adaptation abilities and flexibility of mind. Ackerman is a smooth writer; her presentation of ideas is deft, and her anecdotes are consistently engaging. She demonstrates that birds’ novel or seemingly eccentric behaviors are often clever strategies rooted in evolutionary wisdom as well as complex cognition in different contexts, such as decision-making, finding patterns, and planning for the future. It is becoming increasingly evident that bird vocalization postures express emotions, convey intent, and signal a range of social purposes—e.g., sharing information, negotiating boundaries, influencing behavior. And some bird species “are not just memorizing complex signals but rather applying a generalized grammatical ordering rule to decode messages.” Ackerman demonstrates bird science as an evolving discipline that is consistently fascinating, and she offers brilliant discussions of the use of smell, long overlooked but indeed deployed for navigation; courtship signals; predator avoidance, and, not surprisingly, locating food. There is a captivating section on birds working in concert with ants in foraging as well as an examination of the mean tricks of parasitic chicks and particularly aggressive species. Cowbirds, for example, often show “mafia-like tactics,” and they are “so good [at what they do] that they appear to be contributing to the demise of dozens of already troubled North American songbird species on the brink of extinction from habitat degradation.”

A brightly original book sure to please any nature lover.
