The Carolina parakeet, Heath Hen, Great Auk, Passenger pigeon, Labrador duck and Ivory-billed woodpecker have with their passing come to represent for Cokinos a lot more than simply another group of vanished species. They are emblematic of lost time, effort, habitat, environment, and are missing slice of life. Poignant as his descriptions of their loss is, there is always an element of hope that suffuses each of his chapters.
Cokinos with this book successfully blends history with a little bit of biology and adds just enough personal observation and insight. The mix works and his writing is excellent. There is enough science here to satisfy those who wish to remain at a respectable distance. For those who don't mind getting close there is sufficient reason - through what these birds represent about our past and future on this planet - to allow them to come and perch in your soul.
