Extractions: Natural Causes Extinction is recognized as a natural biological process consistent with the concepts of evolution. Based on fossil records, birds have a mean species lifespan of about 2 million years, while mammals have a mean species lifespan of about 600,000 years. Extinction by natural causes may mean the actual death of a species or the evolution of the species into one or more new forms. Overspecialization, competition, sudden climatic change, or catastrophic events such as earthquakes or volcanic eruptions are natural causes of species' death. Introduced Exotic Predators Introduction of exotic species to ecosystems often disrupts natural systems, especially when a predator is introduced. Native species are seldom adapted to handle these often devastating components of their environment. Sometimes predators are introduced to control another exotic species, thus compounding the biological effects on the system. Exotic predators will inevitably turn to native fauna or flora in search of food. Nonpredatory Exotics Nonpredatory exotics are often agents of competition and/or disease. Other effects may also be attributed to their introduction.

It is unlawful to kill, harm, or harass endangered species. Listed: 35 Federal Register 8495; June 2, 1970 Historical Status: The historical breeding range of the whooping crane extended from Illinois, northwest through North Dakota, and up to the Northwest Territories. The last nesting record for North Dakota was in McHenry County in 1915. The birds historically wintered along the Gulf of Mexico. By the 1940's there were an estimated 21 whooping cranes left in the world. Most were from a flock that wintered at the Aransas National Wildlife Refuge on the coast of Texas. It was later discovered that the birds were breeding in Wood Buffalo National Park in the Northwest Territories. Present Status: There are presently about 145 whooping cranes in the wild. About 132 birds are in the Aransas-Wood Buffalo flock and 13 birds are in a flock that migrates between Grays Lake National Wildlife Refuge in Idaho and Bosque del Apache National Wildlife Refuge in New Mexico. The Aransas-Wood Buffalo population migrates through North Dakota. During the 1991 fall migration there were 8 sightings in North Dakota from late September to mid October. The spring migration occurs from late April to mid June. Birds can show up in all parts of North Dakota although most sightings occur in the western 2/3 of the state.

Extractions: Conservation A. Endangered and threatened species and populations. 1. Diurnal bird of prey species have become endangered or threatened due to poaching, pollution, and habitat destruction. 2. As of August 1994, 18 species of diurnal birds of prey are considered endangered or threatened by the United States Fish and Wildlife Service (USFWS). An endangered species is any species of animal or plant that is in danger of extinction throughout all or a significant portion of its range. A threatened species is a species likely to become endangered in the foreseeable future. Following are a few of the federally listed species: a. Southern bald eagle populations declined dramatically in the 1940s and 1950s due to the heavy use of organochlorine pesticides, such as DDT. In 1974, only 700 breeding pairs existed in the contiguous 48 states (Johnsgard, 1990). The bald eagle began a slow recovery following the ban of DDT in 1972, dieldrin in 1974, and endrin in 1984. At the same time, federal laws were enacted to prevent poaching and disturbance of nest sites. Today, there are about 4,500 pairs of breeding bald eagles in the lower 48 states. The USFWS has proposed a change in their status from endangered to threatened in all but three of the 48 states. b. Peregrine falcons met a fate similar to the bald eagle's, but their population decline due to pesticides was even more dramatic. By 1975, there were no peregrines breeding in the eastern U.S. and only 39 known breeding pairs in the western U.S. Pesticide bans, regulations, and intensive captive breeding and release programs have resulted in the peregrine's comeback. In 1994, approximately 1,000 breeding pairs were recorded in the lower 48 states (The Peregrine Fund, 1994). The American peregrine falcon

"Threatened" (T) species are native species which are likely to become endangered in the forseeable future, or which are declining or rare as determined by biological research and inventory. "Special concern" (SC) species are native species which have been documented by biological research or inventory to have suffered a decline that could threaten the species if allowed to continue unchecked, or which occur in such small numbers or with such restricted distribution or specialized habitat requirements that they could easily become threatened within Massachusetts. Any native species listed as endangered or threatened by the U.S. Fish and Wildlife Service is also included on the state list.

This expression, originally referring to species of plants or animals in danger of dying out, began in the 1980s to be extended to anything or anyone becoming rare. Encyclopedia endangered species, any plant or animal species whose ability to survive and reproduce has been jeopardized by human activities. In 1999 the U.S. government, in accordance with the U.S. Endangered Species Act (1973), classified 935 native species as endangered or threatened, including animals such as the Florida panther, the Key deer, the San Joaquin kit fox, the northern spotted owl, the chinook salmon, the Karner blue butterfly, the snail darter, and the cave crayfish and plants such as the Hawaiian nehe and the clover lupine. Over 500 more species were so classified worldwide.

In addition, many states keep their own lists. The International Union for the Conservation of Nature and Natural Resources maintains an international list, published as the

Listed as species of concern are the Common Loon, American Bittern, Reddish Egret, Red-shouldered Hawk, Snowy Plover, Black Tern, Short-eared Owl, Red-headed Woodpecker, Bell's Vireo, and Golden-winged Warbler. Largely due to loss of habitat, habitat fragmentation, introduced species including domestic cats, and contaminants, many bird species are experiencing serious declines.

Extractions: See our new Endangered Species website! Endangered Species Facts U.S. Fish and Wildlife Service, Region 3 March 1994 The piping plover in the Great Lakes area is an endangered species. Endangered species are animals and plants that are in danger of becoming extinct. The Northern Great Plains and Atlantic Coast piping plovers are threatened species. Threatened species are animals and plants that are likely to become endangered in the foreseeable future. Identifying, protecting, and restoring endangered and threatened species is the primary objective of the U.S. Fish and Wildlife Serviceþs endangered species program. The Great Lakes population of the piping plover is at a perilously low level. Since 1983, the number of nesting pairs has ranged from 12 to 19. All of the Great Lakes pairs nest in Michigan. Scientific Name Charadrius melodus Appearance These small, stocky shorebirds have a sand-colored upper body, a white underside, and orange legs. During the breeding season, adults have a black forehead, a black breast band, and an orange bill. Habitat Piping plovers use wide, flat, open, sandy beaches with very little grass or other vegetation. Nesting territories often include small creeks or wetlands.

Extractions: One of New Jersey's greatest success stories is the Bald Eagle, a species that was brought "back from the brink" of extinction in N.J. This bird is believed to live over thirty years in the wild and longer in captivity. Also called the "American eagle". New Jersey's bald eagle population continued to grow during the 1995 nesting season as 11 pairs nested. Nine of the pairs were successful at raising 20 young. Nests occurred at Bear Swamp, Belleplain State Forest, Cohansey River, Mannington Meadow, Newport, Maurice River, Raccoon Creek/Gibbstown, Stow Creek, Union Lake, Wading River and Round Valley Reservoir. All of the nests, with the exception of the Round Valley nest, are located within the Inner and Outer Coastal Plain of South Jersey. Bald eagles are very sensitive to disturbances, and will abandon their nest sites if people come too close to the nest. Most nests are on private land, and the landowners are the main protectors of nest sites. The state's most productive nest is the Stow Creek pair. This pair has produced three young in three of the past four seasons. In 1998, 14 active pairs (tying 1996's post DDT high) fledged 17 young!
