Here we provide a detailed comparison of the anatomy of Ambiortus relative to other known Early Cretaceous ornithuromorphs from the Chinese Jehol Group and Xiagou Formation. We include new information on Ambiortus from a previously undescribed slab preserving part of the sternum. Ambiortus is superficially similar to Gansus yumenensis from the Aptian Xiagou Forma tion but shares more morphological features with Yixianornis grabaui (Ornithuromorpha: Songlingorni thidae) from the Jiufotang Formation of the Jehol Group. In general, the mosaic pattern of character distri bution among early ornithuromorph taxa does not reveal obvious relationships between taxa. Ambiortus was placed in a large phylogenetic analysis of Mesozoic birds, which confirms morphological observations and places Ambiortus in a polytomy with Yixianornis and Gansus.

Birdobserver17.4 Page183-188 an Honor Without Profit Richard K
AN HONOR WITHOUT PROFIT by Richard K. Walton eponymy n The derivation of a name of a city, country, era, institution, or other place or thing from the name of a person. Gruson in his Words for Birds gives seven categories for the origins of common bird names: appearance (Black-capped Chickadee), eponymy (Henslow’s Sparrow), echoics (Whooping Crane), habitat (Marsh Wren), behavior (woodpecker), food (oystercatcher), and region (California Condor). The second category comprises people and places memorialized in bird names. Many of our most famous ornithologists as well as a fair number of obscure friends and relations have been so honored. A majority of these names were given during the eighteenth and nineteenth centuries, the pioneering era of North American ornithology. While some of these tributes are kept alive in our everyday birding language, others have slipped into oblivion. Recognition or obscurity may ultimately hinge on the names we use for birds. There is no more famous name in the birding culture than that of John James Audubon. His epic The Birds of America was responsible for putting American science, art, and even literature on the international map. This work was created, produced, promoted, and sold largely by Audubon himself. In the years since his death in 1851, the Audubon legend has been the inspiration for a multitude of ornithological pursuits and causes, both professional and amateur. Audubon painted some five hundred birds in Birds of America and described these in his five-volume Ornithological Biographies. Many of the names given by Audubon honored men and women of his era. -
Thinking with Birds: Mary Elizabeth Barber's Advocacy for Gender
Thinking with Birds: Mary Elizabeth Barber’s Advocacy for Gender Equality in Ornithology TANJA HAMMEL Department of History, University of Basel This article explores parts of the first South African woman ornithologist’s life and work. It concerns itself with the micro-politics of Mary Elizabeth Barber’s knowledge of birds from the 1860s to the mid-1880s. Her work provides insight into contemporary scientific practices, particularly the importance of cross-cultural collaboration. I foreground how she cultivated a feminist Darwinism in which birds served as corroborative evidence for female selection and how she negotiated gender equality in her ornithological work. She did so by constructing local birdlife as a space of gender equality. While male ornithologists naturalised and reinvigorated Victorian gender roles in their descriptions and depictions of birds, she debunked them and stressed the absence of gendered spheres in bird life. She emphasised the female and male birds’ collaboration and gender equality that she missed in Victorian matrimony, an institution she harshly criticised. Reading her work against the background of her life story shows how her personal experiences as wife and mother as well as her observation of settler society informed her view on birds, and vice versa. Through birds she presented alternative relationships to matrimony. Her protection of insectivorous birds was at the same time an attempt to stress the need for a New Woman, an aspect that has hitherto been overlooked in studies of the transnational anti-plumage -

Observebserve a D Dinosaurinosaur
OOBSERVEBSERVE A DDINOSAURINOSAUR How did ancient dinosaurs move and behave? To fi nd out, paleontologists look for clues in fossils, such as fossilized footprints, eggs, and even dung. They also observe and analyze the movement and behavior of living dinosaurs and other animals. These data help paleontologists interpret the fossil evidence. You can also observe living dinosaurs. Go outdoors to fi nd birds in their natural habitat. (Or you can use online bird videos, such as the Cornell Lab of Ornithology’s video gallery at www.birds.cornell.edu/AllAboutBirds/ BirdGuide/VideoGallery.html) 1.

The Making of a Conservationist: Audubon's Ecological Memory
Journal of Ecocriticism 5(2) July 2013 The Making of a Conservationist: Audubon’s Ecological Memory Christian Knoeller (Purdue University)* Abstract While Audubon’s exploits as consummate artist, accomplished naturalist, and aspiring entrepreneur are widely recognized, his contributions as author and nascent conservationist remain less fully appreciated. Extensive travels observing and documenting wildlife as an artist-naturalist gave him a unique perspective on how human-induced changes to the landscape impacted wildlife. He lamented the reduction in range of many species and destruction of historic breeding grounds, as well as declining populations caused by overhunting and habitat loss. His understanding of changing landscapes might be thought of in terms of ecological memory reflected in his narratives of environmental history. He described the destruction of forests and fisheries as well as the shrinking ranges of species including several now extinct such as the Passenger Pigeon, Carolina Parakeet, and Ivory-billed Woodpecker. Quadrupeds of North America and the Missouri River Journals depict the impact of environmental destruction he witnessed taking place in the first half of the 19th century. While these later works suggest a growing interest in conservation, Audubon had already voiced such concerns frequently in his earlier writings. Copious journals kept throughout his career in the field on America’s westering frontier reveal a keen appreciation for environmental history. By the time he arrived on the Upper Missouri in 1843, his values regarding the preservation of wildlife and habitat had been forged by writing for decades about his observations in the wild. What began as a quest to celebrate the natural abundance of North America by documenting every species of bird took on new dimensions as he expressed increasing concerns about conservation having recognized the extent of development and declines in wildlife during his lifetime. -

(Evolution) Prior to Darwin's Origin of Species
Theories of Species Change (Evolution) Prior to Darwin’s Origin of Species Theories of Species Change Prior to Darwin Entangled with: 1. Theories of geological change. 2. Theories of heredity. 3. And theories of ontogenesis, that is, of individual development– embryology. Notions of Species in the Classical Period of Greece Plato: the essence or form of an organism is eternal and unchanging; embodiment only the appearance of that form. Aristotle: the essence or form of an organism is incorporated in the physical body; the only kind of eternity enjoyed is through continued reproduction. Theories of Species Change in the Early Modern Period Descartes: gradual evolution of physical system according to fix laws (Discourse on Method, 1628). Buffon (1707-88) and Linnaeus (1707-78): God created a limited number of species, but through hybridization and impact of environment, new species appear. Kant: evolutionary development from earth possible only if earth already construed as purposive; species change possible but no evidence (Critique of Judgment, 1790). Transformation of one species into another through change of scaling, from D’Arcy Thompson, On Growth and Form (1942). Carus’s illustration of the Richard Owen’s illustration of the archetype archetype, from his On the Nature of Limbs (1849) Georges Cuvier (1769-1832). Portrait by François-André Vincent Adam’s Mammoth, found in Siberia in 18th century; St. Petersburg Natural History Museum Cuvier’s illustration of the Siberian mammoth; he identified it as an extinct species of elephant (1796). Cuvier’s illustration of the “Ohio Animal,” which he named “mastodon.” Megatherium (i.e., “large animal”), discovered in South America, described by Cuvier as an extinct creature similar to the modern sloth.
