The bald eagle is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle, which occupies the same niche as the bald eagle in the Palearctic. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting.
The California condor is a New World vulture and the largest North American land bird. It became extinct in the wild in 1987 when all remaining wild individuals were captured, but has since been reintroduced to northern Arizona and southern Utah, the coastal mountains of California, and northern Baja California in Mexico. It is the only surviving member of the genus Gymnogyps, although four extinct members of the genus are also known. The species is listed by the International Union for the Conservation of Nature as Critically Endangered, and similarly considered Critically Imperiled by NatureServe.
The whooping crane is an endangered crane species, native to North America, named for its “whooping” calls. Along with the sandhill crane, it is one of only two crane species native to North America, and it is also the tallest North American bird species. The whooping crane's lifespan is estimated to be 22-24 years in the wild. After being pushed to the brink of extinction, due to unregulated hunting and loss of habitat, and just 21 wild cranes remaining by 1941, conservation efforts would lead to a partial recovery. The total number of cranes in the surviving migratory population, plus three reintroduced flocks and in-captivity, only slightly exceeds 800 birds as of 2020.
The Oregon Zoo, originally the Portland Zoo and later the Washington Park Zoo, is a zoo located in Washington Park, Portland, Oregon, approximately 2 miles (3.2 km) southwest of downtown Portland. Founded in 1888, it is the oldest zoo west of the Mississippi River.
The Endangered Species Act of 1973 is the primary law in the United States for protecting and conserving imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation". The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed. It therefore "protect[s] species and the ecosystems upon which they depend" through different mechanisms. For example, section 4 requires the agencies overseeing the Act to designate imperiled species as threatened or endangered. Section 9 prohibits unlawful ‘take,’ of such species, which means to "harass, harm, hunt..." Section 7 directs federal agencies to use their authorities to help conserve listed species. The Act also serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The Supreme Court found that "the plain intent of Congress in enacting" the ESA "was to halt and reverse the trend toward species extinction, whatever the cost." The Act is administered by two federal agencies, the United States Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS). FWS and NMFS have been delegated by the Act with the authority to promulgate any rules and guidelines within the Code of Federal Regulations (CFR) to implement its provisions.
Dichlorodiphenyldichloroethylene (DDE) is a chemical compound formed by the loss of hydrogen chloride (dehydrohalogenation) from DDT, of which it is one of the more common breakdown products. Due to DDT's massive prevalence in society and agriculture during the mid 20th century, DDT and DDE are still widely seen in animal tissue samples. DDE is particularly dangerous because it is fat-soluble like other organochlorines; thus, it is rarely excreted from the body, and concentrations tend to increase throughout life. The major exception is the excretion of DDE in breast milk, which transfers a substantial portion of the mother's DDE burden to the young animal or child. Along with accumulation over an organism's lifetime, this stability leads to bioaccumulation in the environment, which amplifies DDE's negative effects.
Karl E. Mundt National Wildlife Refuge is located mostly in the southern part of the U.S. state of South Dakota, with a small extension into northern Nebraska, and includes 1,085 acres (4.39 km2) The refuge is a part of the Lake Andes National Wildlife Refuge Complex and is managed by the U.S. Fish and Wildlife Service. Of the land area in the district, the U.S. Government owns only 780 acres (3.15 km2), while the remaining area is managed as an easement. The refuge is closed to the public but there are excellent viewing locations from the Ft. Randle Dam on the Missouri River. The Karl E. Mundt NWR has the largest concentration of bald eagles in the lower 48 states, with over 200 eagles often spending the winter on the refuge. The refuge was named for former South Dakota Senator Karl Mundt, who was a strong supporter of the Endangered Species Act of 1966.
The Catalina Island Conservancy is a nonprofit organization established to protect and restore Santa Catalina Island, California, United States. The Conservancy was established in 1972 through the efforts of the Wrigley and Offield families. The Conservancy was created when both families deeded 42,135 acres (170.51 km2) of the island over to the organization—88% of the Island.
The Ventana Wilderness of Los Padres National Forest is a federally designated wilderness area located in the Santa Lucia Range along the Central Coast of California. This wilderness was established in 1969 when the Ventana Wilderness Act redesignated the 55,800-acre (22,600 ha) Ventana Primitive Area as the Ventana Wilderness and added land, totalling 98,000 acres. In 1978, the Endangered American Wilderness Act added 61,000 acres, increasing the total wilderness area to about 159,000 acres. The California Wilderness Act of 1984 added about 2,750 acres. The Los Padres Condor Range and River Protection Act of 1992 created the approximately 14,500-acre (5,900 ha) Silver Peak Wilderness and added about 38,800 acres to the Ventana Wilderness in addition to designating the Big Sur River as a Wild and Scenic River. The Big Sur Wilderness and Conservation Act of 2002 expanded the wilderness for the fifth time, adding nearly 35,000 acres (14,000 ha), increasing the total acreage of the wilderness to its present size of 240,026 acres (97,135 ha).
The Blackwater National Wildlife Refuge was established in 1933 as a waterfowl sanctuary for birds migrating along the critical migration highway called the Atlantic Flyway. The refuge is located on Maryland's Eastern Shore, just 12 mi (19 km) south of Cambridge, Maryland in Dorchester County, and consists of over 28,000 acres (110 km2) of freshwater impoundments, brackish tidal wetlands, open fields, and mixed evergreen and deciduous forests. Blackwater NWR is one of over 540 units in the National Wildlife Refuge System, which is managed by the United States Fish and Wildlife Service.
The Sespe Condor Sanctuary is a 53,000-acre (210 km2) wildlife refuge in the Topatopa Mountains, in northeastern Ventura County, California. It is within the Sespe Wilderness in the southern Los Padres National Forest.
The Peregrine Fund is a non-profit organization founded in 1970 that conserves threatened and endangered birds of prey worldwide. The successful recovery of the peregrine falcon in the United States, which was removed from the U.S. Endangered Species List in 1999, enabled the organization to expand its mission to include other endangered raptors around the world. The Peregrine Fund is headquartered at its World Center for Birds of Prey in Boise, Idaho, on a 580-acre (2.3 km2) campus with breeding and research facilities, an administrative office, interpretive center, research library, and archives.
The Bald and Golden Eagle Protection Act is a United States federal statute that protects two species of eagle. The bald eagle was chosen as a national emblem of the United States by the Continental Congress of 1782 and was given legal protection by the Bald Eagle Protection Act of 1940. This act was expanded to include the golden eagle in 1962. Since the original Act, the Bald and Golden Eagle Protection Act has been amended several times. It currently prohibits anyone, without a permit issued by the Secretary of the Interior, from "taking" bald eagles. Taking is described to include their parts, nests, or eggs, molesting or disturbing the birds. The Act provides criminal penalties for persons who "take, possess, sell, purchase, barter, offer to sell, purchase or barter, transport, export or import, at any time or any manner, any bald eagle ... [or any golden eagle], alive or dead, or any part, nest, or egg thereof."
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
The Bitter Creek National Wildlife Refuge is located in the foothills of the southwestern San Joaquin Valley in Kern County, California. The refuge is one of four units of the Hopper Mountain National Wildlife Refuge Complex for California condors.
Hopper Mountain National Wildlife Refuge is located in the Topatopa Mountains of Ventura County, in southern California. It is bordered by the Los Padres National Forest and the Sespe Condor Sanctuary to the north. The 2,471-acre (10.00 km2) refuge was established in 1974 to protect the endangered California condor, its habitat, and other wildlife resources.
An out-of-danger species is an animal or plant species formerly categorized as Rare, Vulnerable, or Endangered that has since been removed from these lists because the species' survival has been relatively secured, e.g. Ginkgo biloba. Often known as a delisted species, these animals have been moved out of the Rare, Vulnerable, or Endangered categories through conservation efforts and government policymaking to ensure their survival and population growth. The International Union for Conservation of Nature (IUCN) established its list of endangered species in 1964, subsequently becoming a global authority on wildlife conservation. The following year, the United States created the U.S. Fish and Wildlife Service to act as a federal authority on endangered species. Currently, both international and domestic organizations implement recovery efforts and track species' population growth, delisting when necessary. Removing a species from the endangered species list is generally a slow process; most organizations and governments require long periods of observation both before and after delisting. There have been numerous efforts to delist endangered species, with both international and country-wide recovery plans being regularly implemented. These programs have led to the recovery of dozens of species, but their overall effectiveness remains contested.
The Dolan Fire was a large wildfire that burned in the Big Sur region and other parts of the Santa Lucia mountain range in Monterey County, California, in the United States as part of the 2020 California wildfire season. The fire began at approximately 8:15 p.m. on August 18, 2020. On September 8, 15 firefighters were injured, one critically, when they were forced to deploy emergency fire shelters at Nacimiento Station. Ten adult California condors and two chicks died in the blaze, which began about a mile south of the Big Sur Condor Sanctuary in Monterey County. The nonprofit Ventana Wildlife Society of Monterey lost a sanctuary that has been used to release the captive-bred condors into the wild since 1997. While no people or condors were at the 80-acre (32 ha) site, a research building, pens, and other facilities were destroyed.
Jan Hamber is an American ornithologist and conservationist. While working at the Santa Barbara Museum of Natural History in the 1970s, she became involved in the effort to save the California condor, and has been credited with playing a major role in the condor's survival in the wild. Hamber was the biologist who tracked the last known California condor in the wild, placing the phone call that led to its capture at the beginning of the successful captive breeding program that saved condors from becoming extinct.
