Similar comparisons can be made with other bird features such as how their hips work. Many dinosaurs had feathers covering or adorning their bodies, but again, modern birds use feathers in ways that overlap with but are different from how those early non-bird dinosaurs used them (see: On The Threshold Of Flight.

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.

But that is science in hierarchical institutions). For comparison, here is a photo of the same species taken at Nanhui, Shanghai, far further east.

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. I appreciate the addition of pencil drawings in some species accounts to illustrate structural features.

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.

Science proving the obvious again, part 78 : Eurasian Spoonbills preferred departing from one of their stopover sites when tailwind conditions were good. eBird calls the Eurasian Woodcock a “bizarre and cumbersome-looking relative of the snipes”, which is a pretty good description, I think.

If this comparison bothers you, here’s something to comfort you (but not me): Donald Trump will be the next US president, the squirrel will not. Which sounds like a species name taken from a science fiction novel for children. A giant squirrel, actually. Attack of the giant squirrels from Mars.

As much as recent field guides have tried to include more vagrant birds, there just isn’t enough space for the kind of detailed comparisons provided here. He has led birding tours for many years and is a research associate at Point Blue Conservation Science. This is valuable material.

Describing gull plumage is a combination of science, graphic art, and visual metaphor. A quick comparison of several accounts from both books indicate that the descriptions are re-written, sometimes totally.

Though to be historically accurate, the breaking wheel would be a better comparison. But then, maybe not – it seems to be the nature of science that the more you know, the more you want to know. Guantanamo for frogs. So much for this post’s pseudo-philosophical thought.
