Operation Migration

picture info	Operation Migration Operation Migration was a nonprofit, charitable organization, which developed a method using ultralight aircraft to teach migration to captive-raised, precocial bird species such as Canada geese, trumpeter swans, sandhill cranes, and endangered whooping cranes. Background Operation Migration Canada was founded in 1994 as a Canadian registered charity. Operation Migration-USA Inc was established in 1999 as a 501(c)(3) nonprofit organization. In collaboration with the Whooping Crane Eastern Partnership, Operation Migration participated in the reintroduction of endangered Whooping cranes into eastern North America beginning in 2001 and continuing until the last small flock was lead south in 2015. It is believed by conservationists that approximately 500–1,400 whooping cranes existed in 1860. Their population declined because of hunting and habitat loss until 1941 when the last migrating flock dwindled to an all-time low of 15 birds; all birds of this species alive today are d ...

picture info	Ornithology In Canada Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
