Similar comparisons can be made with other bird features such as how their hips work. Most likely, the researchers have indicated, the hatched birds would be viable and not too different from regular chickens, possibly less different than some of the odd breeds generated by more traditional methods. Here’s the thing.

These are extremely detailed, covering distribution, behavior, and plumage by age and gender (when relevant) and comparisons with other species in and external to the group. Light blue boxes give brief facts on breeding age, strategy and lifespan. Additional information is presented in boxes and with photographs.

The Vocalizations section describes the species’ diagnostic and less diagnostic calls, twitters, chatters, and songs using transliteration and comparisons, also describing the pace and acoustic quality of the sounds. (In The spectrograms are much easier to read in this volume, larger and darker.

There are also two pages illustrating the “Holistic Approach,” silhouettes of each species (Western birds on the left, Eastern birds on the right), that allow for comparison of structure, size, and shape. The maps are fairly complex, showing breeding range, winter range, year-round range, migration routes, times, and directions.

This is a delightful book, large (8-1/2 by 11 inches), filled with Sibley’s distinctive artwork and an organized potpourri of research-based stories about the science behind bird’s lives. copyright @2020 by David A llen Sibley. As Sibley tells us in the Preface, he originally intended to write a children’s book.

The authors examine migration related traits and address the theoretical problems of massive comparisons across large numbers of physical features and behaviors across many species. Loons hardly ever fly when they are on their breeding grounds or their winter-water, but the migration is for many loons a non-trivial distance.

These have been used by meteorologists, technicians, and researchers who spend about 13 months on the island at a time researching a variety of sciences. About half of all breeding Wandering Albatross nest on the Prince Edward Islands. It is still volcanically active with researchers periodically discovering new flows. and seabirders.
