Taiwain Post Co. Ltd. , 2008. Hardcover. New/No Dustjacket as issued. . New Old Stock. Text in Chinese and English. A hardcover book with text and many photos of the birds in color. About 8 1/2" x 11 1/4"; 24 pages, with slipcase. Includes 4 individual stamps, a Souvenir sheet with 4 stamps, and 4 post cards from the Republic of China -Taiwan distributed in pocket through text. The Taiwan blue magpie is a member of the Corvidae family and a protected species endemic to Taiwan. Its head and breast are black. The rest of its body is blue. Its tail feathers are exceptionally long. The bird’s gorgeous plumage makes it a frequent target of hunters. Overdevelopment and pollution pose an even more serious threat. To call attention to the importance of ecological conservation, this Post specially commissioned Professor Yuan Hsiao-wei at National Taiwan University to plan a set of four stamps and a souvenir sheet on the Taiwan blue magpie. The stamp designs follow: 1. Foraging: Taiwan blue magpie is an omnivorous bird. Its diverse diet, group living habit, large stature, and combative nature are all advantageous traits in terms of survival. Its food storing behavior gives it another survival advantage in the face of natural change. 2. Rearing the young: Taiwan blue magpies are cooperative breeders; individuals other than a chick’s parents, including both other adults and sub-adults, can help provide care and that ensure group survival. 3. Sub-adults: In most bird species, the parents gradually drive their young away to find their own territory after they are grown, yet the sub-adults of Taiwan blue magpies stay to help rear their younger siblings. 4. Flying: Also known as “long-tailed mountain ladies,” Taiwan blue magpies live in groups. When they fly in a line, it appears as if they are building beautiful “bird bridges” in the forests. The sight is magnificent., Taiwain Post Co. Ltd., 2008, 6, New. We are interested in the evolution of hominin diets for several reasons. One is the fundamental concern over our present-day eating habits and the consequences of our societal choices, such as obesity prevalent in some cultures and starvation in others. Another is that humans have learned to feed themselves in extremely varied environments, and these adaptations, which are fundamentally different from those of our closest biological relatives, have to have had historical roots of varying depth. The third, and the reason why most paleoanthropologists are interested in this question, is that a species' trophic level and feeding adaptations can have a strong effect on body size, locomotion, "life history strategies", geographic range, habitat choice, and social behavior. Diet is key to understanding the ecology and evolution of our distant ancestors and their kin, the early hominins. A study of the range of foods eaten by our progenitors underscores just how unhealthy many of our diets are today. This volume brings together authorities from disparate fields to offer new insights into the diets of our ancestors. Paleontologists, archaeologists, primatologists, nutritionists and other researchers all contribute pieces to the puzzle. This volume has at its core four main sections: · Reconstructed diets based on hominin fossils—tooth size, shape, structure, wear, and chemistry, mandibular biomechanics · Archaeological evidence of subsistence—stone tools and modified bones · Models of early hominin diets based on the diets of living primates—both human and non-human, paleoecology, and energetics · Nutritional analyses and their implications for evolutionary medicine New techniques for gleaning information from fossil teeth, bones, and stone tools, new theories stemming from studies of paleoecology, and new models coming from analogy with modern humans and other primates all contribute to our understanding. When these approaches are brought together, they offer an impressive glimpse into the lives of our distant ancestors. The contributions in this volume explore the frontiers of our knowledge in each of these disciplines as they address the knowns, the unknowns, and the unknowables of the evolution of hominin diets., 6<
