Hanson lives in the U.S. state of Washington with his wife and son.
Archaeopteryx, sometimes referred to by its German name, "Urvogel", is a genus of bird-like dinosaurs. The name derives from the ancient Greek ἀρχαῖος (archaīos), meaning "ancient", and πτέρυξ (ptéryx), meaning "feather" or "wing". Between the late 19th century and the early 21st century, Archaeopteryx was generally accepted by palaeontologists and popular reference books as the oldest known bird. Older potential avialans have since been identified, including Anchiornis, Xiaotingia, and Aurornis.
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 million years ago; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are modern feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage to survive the Cretaceous–Paleogene extinction event approximately 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and the extinct non-avian dinosaurs, which are all dinosaurs other than birds.
Edward Osborne Wilson was an American biologist, naturalist, and writer. His specialty was myrmecology, the study of ants, on which he was called the world's leading expert, and he was nicknamed Ant Man.
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on dinosaurs, both avian (bird) and some non-avian (non-bird) and possibly other archosauromorphs. They are considered the most complex integumentary structures found in vertebrates and a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups.

Craig Stanford is Professor of Biological Sciences and Anthropology at the University of Southern California. He is also a Research Associate in the herpetology section of the Los Angeles County Natural History Museum. He is known for his field studies of the behavior, ecology and conservation biology of chimpanzees, mountain gorillas and other tropical animals, and has published more than 140 scientific papers and 17 books on animal behavior, human evolution and wildlife conservation. He is best known for his field study of the predator–prey ecology of chimpanzees and the animals they hunt in Gombe National Park, Tanzania, and for his long term study of the behavior and ecology of chimpanzees and mountain gorillas in Bwindi Impenetrable National Park, Uganda.
Feathers are epidermal growths which form an outer covering on birds and some dinosaurs.

The evolution of birds began in the Jurassic Period, with the earliest birds derived from a clade of theropod dinosaurs named Paraves. Birds are categorized as a biological class, Aves. For more than a century, the small theropod dinosaur Archaeopteryx lithographica from the Late Jurassic period was considered to have been the earliest bird. Modern phylogenies place birds in the dinosaur clade Theropoda. According to the current consensus, Aves and a sister group, the order Crocodilia, together are the sole living members of an unranked "reptile" clade, the Archosauria. Four distinct lineages of bird survived the Cretaceous–Paleogene extinction event 66 million years ago, giving rise to ostriches and relatives (Paleognathae), ducks and relatives (Anseriformes), ground-living fowl (Galliformes), and "modern birds" (Neoaves).
The scientific question of within which larger group of animals birds evolved has traditionally been called the 'origin of birds'. The present scientific consensus is that birds are a group of maniraptoran theropod dinosaurs that originated during the Mesozoic Era.
Nalini Nadkarni is an American ecologist who pioneered the study of Costa Rican rain forest canopies. Using mountain climbing equipment to make her ascent, Nadkarni first took an inventory of the canopy in 1981, followed by two more inventories in 1984.
The John Burroughs Medal, named for nature writer John Burroughs (1837–1921), is awarded each year in April by the John Burroughs Association to the author of a book that the association has judged to be distinguished in the field of natural history. Only twice has the award been given to a work of fiction.

Carla J. Dove is an American researcher who specializes in identifying birds that have gotten trapped in airplane engines, known as bird strikes. She is currently the Program Manager for Feather Identification Lab in the Division of Birds at the National Museum of Natural History. Her work helps promote wildlife safety, as well as pave the way for the development of preventative measures that will decrease the chance of wildlife impacting airplanes. She has published over 40 articles on her research so far.
