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. It is still volcanically active with researchers periodically discovering new flows.

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.

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.

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. Sullivan are birders as well as writers, researchers, and organizational administrators, and this makes a big difference. Authors George L. Armistead and Brian L.
