WBird conservation is a field in the science of conservation biology related to threatened birds. Humans have had a profound effect on many bird species. Over one hundred species have gone extinct in historical times, although the most dramatic human-caused extinctions occurred in the Pacific Ocean as humans colonised the islands of Melanesia, Polynesia and Micronesia, during which an estimated 750–1800 species of bird became extinct. According to Worldwatch Institute, many bird populations are currently declining worldwide, with 1,200 species facing extinction in the next century. The biggest cited reason surrounds habitat loss. Other threats include overhunting, accidental mortality due to structural collisions, long-line fishing bycatch, pollution, competition and predation by pet cats, oil spills and pesticide use and climate change. Governments, along with numerous conservation charities, work to protect birds in various ways, including legislation, preserving and restoring bird habitat, and establishing captive populations for reintroductions.

WBelize Bird Rescue (BBR) is an avian rescue and rehabilitation centre in Belize.
WBird ringing or bird banding is the attachment of a small, individually numbered metal or plastic tag to the leg or wing of a wild bird to enable individual identification. This helps in keeping track of the movements of the bird and its life history. It is common to take measurements and examine conditions of feather molt, subcutaneous fat, age indications and sex during capture for ringing. The subsequent recapture or recovery of the bird can provide information on migration, longevity, mortality, population, territoriality, feeding behavior, and other aspects that are studied by ornithologists. Other methods of marking birds may also be used to allow for field based identification that does not require capture.
WGuy Morrell Bradley was an American game warden and deputy sheriff for Monroe County, Florida. Born in Chicago, Illinois, he relocated to Florida with his family when he was young. As a boy, he often served as guide to visiting fishermen and plume hunters, although he later denounced poaching after legislation was passed to protect the dwindling number of birds. In 1902, Bradley was hired by the American Ornithologists' Union, at the request of the Florida Audubon Society, to become one of the country's first game wardens.
WCormorant culling is the intentional killing of cormorants by humans for the purposes of wildlife management. It has been practiced for centuries, with supporters of culling generally arising from the angling community. Culling techniques may involve the killing of birds, the destruction of eggs or both. Historically, culls have occurred to protect the interests of recreational and commercial fishermen who perceive the animals to be competing with them for their intended catch or for the prey of their intended catch. Since the 1960s, the growing aquaculture industry has undertaken cormorant culls to protect its farmed fish and crustacean stocks. Opponents of cormorant culling include conservation groups such as the National Audubon Society, Cormorant Defenders International and Sea Shepherd.
WThe Federal Duck Stamp, formally known as the Migratory Bird Hunting and Conservation Stamp, is an adhesive stamp issued by the United States federal government that must be purchased prior to hunting for migratory waterfowl such as ducks and geese. It is also used to gain entrance to National Wildlife Refuges that normally charge for admission. It is widely seen as a collectable and a means to raise funds for wetland conservation, with 98% of the proceeds of each sale going to the Migratory Bird Conservation Fund.
WJack Rodney Finch was an American conservationist known primarily for his efforts to save the eastern bluebird. He was known as The Birdman of Bailey.
WAt one time, the golden eagle lived in a great majority of temperate Europe, North Asia, North America, North Africa, and Japan. Although widespread and quite secure in some areas, in many parts of the range golden eagles have experienced sharp population declines and have even been extirpated from some areas. The total number of individual golden eagles from around the range is estimated to range somewhere between 170,000 and 250,000 while the estimated total number of breeding pairs ranges from 60,000 to 100,000. Few other eagle species are as numerous, though some species like tawny eagle, wedge-tailed eagle and bald eagle have total estimated populations of a similar size to the golden eagle's despite having distributions which are more restricted. The world's most populous eagle may be the African fish eagle, which has a stable total population estimated at 300,000 individuals and is found solely in Africa. On a global scale, the golden eagle is not considered threatened by the IUCN.

WSeabirds include some of the most threatened taxa anywhere in the world. For example, of extant albatross species, 82% are listed as threatened, endangered, or critically endangered by the International Union for Conservation of Nature. The two leading threats to seabirds are accidental bycatch by commercial fishing operations and introduced mammals on their breeding islands. Mammals are typically brought to remote islands by humans either accidentally as stowaways on ships, or deliberately for hunting, ranching, or biological control of previously introduced species. Introduced mammals have a multitude of negative effects on seabirds including direct and indirect effects. Direct effects include predation and disruption of breeding activities, and indirect effects include habitat transformation due to overgrazing and major shifts in nutrient cycling due to a halting of nutrient subsidies from seabird excrement. There are other invasive species on islands that wreak havoc on native bird populations, but mammals are by far the most commonly introduced species to islands and the most detrimental to breeding seabirds. Despite efforts to remove introduced mammals from these remote islands, invasive mammals are still present on roughly 80% of islands worldwide.
WA light level geolocator, light-level logger or GLS is essentially a lightweight, electronic archival tracking device, usually used in bird migration research to map migration routes, identify important staging areas, and sometimes provide additional ecological information.

WA nest box, also spelled nestbox, is a man-made enclosure provided for animals to nest in. Nest boxes are most frequently utilized for birds, in which case they are also called birdhouses or a birdbox/bird box, but some mammalian species such as bats may also use them. Placing nestboxes or roosting boxes may also be used to help maintain populations of particular species in an area. The modern nest box was invented by the British conservationist Charles Waterton in the early 19th century to encourage more birdlife and wildfowl on the nature reserve he set up on his estate.
WThe North Slob is an area of mud-flats at the estuary of the River Slaney at Wexford Harbour, Ireland. The North Slob is an area of 10 km2 that was reclaimed in the mid-19th century by the building of a sea wall. It is the lowest geographical point in the Republic of Ireland
WOperation Migration was a non-profit, charitable organization, which developed a method utilizing ultralight aircraft to teach migration to captive-raised, precocial bird species such as Canada geese, trumpeter swans, sandhill cranes and endangered whooping cranes.
WPlume hunting is the hunting of wild birds to harvest their feathers, especially the more decorative plumes which were sold for use as ornamentation, such as aigrettes in millinery. The movement against the plume trade in the United Kingdom was led by Etta Lemon and other women and led to the establishment of the Royal Society for the Protection of Birds. The plume trade was at its height in the late 19th and was brought to an end in the early 20th century.
WRaptor conservation concerns are threats affecting the population viability of birds of prey. Because of their hunting lifestyle, raptors face distinct conservation challenges. As top predators, they are important for healthy ecosystem functioning, and by protecting them many other species are safeguarded. Their extensive habitat requirements make regional conservation strategies necessary for protecting birds of prey.
WThe black robin or Chatham Island robin is an endangered bird from the Chatham Islands off the east coast of New Zealand. It is closely related to the South Island robin. It was first described by Walter Buller in 1872. The binomial commemorates the New Zealand botanist Henry H. Travers (1844–1928). It is also known as kakaruia (Māori) or karure (Moriori). Unlike its mainland counterparts, its flight capacity is somewhat reduced. Evolution in the absence of mammalian predators made it vulnerable to introduced species, such as cats and rats, and it became extinct on the main island of the Chatham group before 1871, being restricted to Little Mangere Island thereafter.
