Similar comparisons can be made with other bird features such as how their hips work. So this new research is very interesting, and we applaud the scientists for their work. These researchers carried out two different major efforts that in combination advance our understanding of the evolution of the bird beak.

So comparisons of bill shapes, foot shapes, and the like can certainly stimulate the imagination, but we need rigorous science to explore and synthesize more molecular work, morphological analysis, and biogeographical hypotheses in order to close more gaps in our understanding.

Birding by Impression is a conscious, deliberate method of identifying and recognizing birds based on the study and evaluation of “distinctive structural features and behavioral movements” and comparison with nearby and similar species. So say Kevin T. Gladwell is a good read, but not credible scientific support.

The birding process is stripped to the essentials without losing the significance of important, sometimes complex ideas—migration, habitat, research, documentation, community. The focus is on learning by doing, with 12 Activity sections integrated within the eleven (ten plus a “bonus”) chapters.

South Africa is their steward and have been declared Special Nature Reserves under the South African Environmental Management: Protected Areas Act in 2003, which restricts activities on the islands to research and conservation management.

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.

Way back when I started what turned out to be my thesis research (on humans), it became important for me to learn about bird migration. I was involved in the study of human movement and navigation on land, and there was a lot of research coming out about bird navigation. That’s because the two are related. 2 PIERSMA, T.,
