"Since long before medieval times cranes have been considered messengers of the gods, calling annually from on high to remind humans below of the passing years and of their own mortality. Now it is up to humans to take responsibility for controlling our own fate--and also to cry out to protect not only cranes but all the other wonderful creatures that share our increasingly fragile and threatened planetary ecosystem with us."
--Paul A. Johnsgard, from the acknowledgments
Johnsgard has substantially updated and significantly expanded his 1991 work Crane Music, incorporating new information on the biology and status of these two North American cranes and providing abbreviated summaries on the other thirteen crane species of the world. The stories of these birds and their contrasting fates provide an instructive and moving history of bird conservation in North America. A Chorus of Cranes is a gorgeous and invaluable resource for crane enthusiasts, birders, natural historians, and conservationists alike.
