American burying beetle (Nicrophorus americanus)

Status: Endangered Critical habitat: none
Listed: 8/13/1989 Recovery plan: 9/27/1991
   

Range: AR(b), KS(b), MA(b), NE(b), OH(b), OK(b), RI(b), SD(b), TX(b) --- AL(x), CT(x), DE(x), DC(x), FL(x), GA(x), IL(x), IN(x), IA(x), KY(x), LA(x), ME(x), MD(x), MI(x), MN(x), MS(x), MO(x), MT(x), NH(x), NY(x), NJ(x), NC(x), ND(x), PA(x), SC(x), TN(x), VT(x), VA(x), WV(x), WI(x)

SUMMARY
The cause of the American burying beetle's 90% range loss is not well understood, but is thought to be due to disruptions in the food and reproductive web. It is threatened by competition, drought, invasive ants and habatat loss. When listed as endangered in 1989, there were only two known populations. Captive breeding, reintroduction efforts and intensive surveys have increased the total number of populations to 20 or more in 2011.

Arctic peregrine falcon (Falco peregrinus tundrius)

Status: DelistedCritical habitat: none
Listed: 6/2/1970Recovery plan: 6/30/1991
   

Range: AL(m), AK(b), AZ(m), AR(m), CA(m), CO(m), CT(m), DE(m), DC(m), FL(m), GA(m), ID(m), IL(m), IN(m), IA(m), KS(m), KY(m), LA(m), ME(m), MD(m), MA(m), MI(m), MN(m), MS(m), MO(m), MT(m), NE(m), NV(m), NH(m), NY(m), NM(m), NJ(m), NC(m), ND(m), OH(m), OK(m), OR(m), PA(m), RI(m), SC(m), SD(m), TN(m), TX(m), UT(m), VT(m), VA(m), WA(m), WV(m), WI(m), WY(m) ---

SUMMARY
The Arctic peregrine falcon declined due to the egg shell-thinning effects of DDT and other organochlorine pesticides. Its listing as an endangered species in 1970 (along with other birds of prey) prompted the EPA to ban DDT in 1972. Counts of migratory Arctic falcons increased from 103 in 1976, to 1,017 in 2004. The species was downlisted to threatened in 1984 and delisted in 1991.

Atlantic leatherback sea turtle (Dermochelys coriacea (Atlantic population))

Status: EndangeredCritical habitat: 3/23/1979
Listed: 6/2/1970Recovery plan: 5/18/1999
   

Range: CT(s), DE(s), FL(b), GA(b), ME(s), MD(s), MA(s), NH(s), NY(s), NJ(s), NC(b), PR(b), RI(s), SC(b), VI(b), VA(s) ---

SUMMARY
The Atlantic leatherback sea turtles declined due to habitat destruction, commercial fishery bycatch, harvest of eggs, hunting of adults, and loss of beach nesting habitat. It is still threatened by these, and in some places by offshore oil drilling. Globally, leatherback sea turtles have been declining for decades. U.S. populations, however, have increased since being listed as endangered in 1970. Between 1989 and 2011, nests at Florida core index beaches increased from 27 to 615.

Atlantic piping plover (Charadrius melodus (Atlantic DPS))

Status: EndangeredCritical habitat: 7/10/2001
Listed: 12/11/1985Recovery plan: 5/18/1999
   

Range: AL(s), CT(b), DE(b), FL(s), GA(s), LA(s), ME(b), MD(b), MA(b), MS(s), NH(b), NY(b), NJ(b), NC(b), PR(s), RI(b), SC(b), TX(s), VA(b) ---

SUMMARY
Atlantic piping plover populations initially declined due to hunting and the millinery trade. With these eliminated, it increased in the first half of the 20th century, but began declining after 1950 due to development, beach crowding and predation. It was listed as 1985 after which intensive habitat protection and control of recreationists and predators, increased its U.S. population from 550 pairs in 1986 to 1,550 in 2011, reaching its overall U.S. recovery goal in 3 of the last 5 years.

Bald eagle (continental U.S. DPS) (Haliaeetus leucocephalus (Continental U.S. DPS))

Status: DelistedCritical habitat: none
Listed: 3/11/1967Recovery plan: 5/18/1999
   

Range: AL(b), AZ(b), AR(b), CA(b), CO(b), CT(b), DE(b), DC(b), FL(b), GA(b), ID(b), IL(b), IN(b), IA(b), KS(b), KY(b), LA(b), ME(b), MD(b), MA(b), MI(b), MN(b), MS(b), MO(b), MT(b), NE(b), NV(b), NH(b), NY(b), NM(b), NJ(b), NC(b), ND(b), OH(b), OK(b), OR(b), PA(b), RI(b), SC(b), SD(b), TN(b), TX(b), UT(b), VT(b), VA(b), WA(b), WV(b), WI(b), WY(b) ---

SUMMARY
The bald eagle declined throughout the lower 48 states, and was extirpate from most of them due to habitat loss, persecution, and DDT-related eggshell thinning. The banning of DDT, increased wetland protection and restoration, and an aggressive, mostly state-based reintroduction program caused eagle pairs to soar from 416 in 1963 to 11,052 in 2007 when the eagle was removed from the endangered list.

Brown pelican (Eastern DPS) (Pelecanus occidentalis (Atlantic/Eastern Gulf Coast DPS))

Status: DelistedCritical habitat: none
Listed: 10/13/1970Recovery plan: 6/30/1980
   

Range: AL(b), CT(o), DE(s), FL(b), GA(b), ME(o), MD(b), MA(o), NH(o), NY(s), NJ(s), NC(b), RI(o), SC(b), VA(b) ---

SUMMARY
Reproductive failure due to eggshell thinning, caused by the pesticide DDT, was the main cause of brown pelican population declines. The pelican has recovered, but now faces threats from offshore oil and wind development, rising sea levels and hurricanes. Brown pelican nests on the Atlantic Coast increased from 2,796 in 1970 to 15,670 in 1999; on the eastern Gulf Coast, nest numbers increased slightly from 5,100 in 1970 to 5,682 in 1999. The eastern brown pelican was delisted in 1985 due to recovery.

Fin whale (Balaenoptera physalus)

Status: EndangeredCritical habitat: none
Listed: 6/2/1970Recovery plan: 7/30/2010
   

Range: AL(o), AK(s), CA(s), CT(s), DE(s), FL(s), GA(s), HI(s), LA(o), ME(s), MD(s), MA(s), MS(o), NH(s), NY(s), NJ(s), NC(s), OR(s), PA(s), RI(s), SC(s), TX(o), VA(s), WA(s) ---

SUMMARY
Fin whales were hunted in all the world's oceans for the first three-quarters of the 20th century, causing population decline. Ongoing threats include illegal and legal whaling, vessel collisions, fishing gear entanglement, reduced prey and noise. Total population size is unknown, but both the North Atlantic and North Pacific populations increased between 1995 and 2009.

Florida panther (Puma concolor coryi)

Status: EndangeredCritical habitat: none
Listed: 3/11/1967Recovery plan: 11/1/2008
   

Range: FL(b) --- AL(x), AR(x), GA(x), LA(x), MS(x), SC(x), TN(x)

SUMMARY
The Florida panther was reduced to near extinction by habitat loss, hunting, persecution, and vehicle collisions. Vehicle collisions, habitat loss and fragmentation, lack of sufficient wildland areas, and in-breeding depression remain current threats. Its population size when listed as endangered in 1967 is unknown, but may have been a little larger than the 30-50 animals recorded throughout the 1980s. The population began to grow after a genetic intervention in 1990s, reaching 130 panthers in 2010.

Gray bat (Myotis grisescens)

Status: EndangeredCritical habitat: none
Listed: 4/28/1976Recovery plan: 7/1/1982
   

Range: AL(b), AR(b), FL(o), GA(o), IL(o), IN(o), KS(o), KY(b), MS(o), MO(b), NC(o), OK(o), TN(b), VA(o), WV(s) ---

SUMMARY
Gray bats declined due to mining, cave disturbance, vandalism, persecution, flooding, deforestation and possibly pesticides. In 2010, they were found with white-nose syndrome, but it is not known if the fungus is lethal to them or not. There were likely at least 5 million gray bats in 1970. At listing in 1976, the gray bat was declining, to a low of 1.5 million bats in 1992. Numbers reached 3.4 million in 2006, the most recent rangewide estimate.

Kemp's ridley sea turtle (Lepidochelys kempii)

Status: EndangeredCritical habitat: none
Listed: 12/2/1970Recovery plan: 9/22/2011
   

Range: AL(o), CT(s), DE(s), FL(o), GA(s), LA(m), ME(s), MD(s), MA(s), MS(m), NH(s), NY(s), NJ(s), NC(s), PR(o), RI(s), SC(o), TX(b), VI(o), VA(s) ---

SUMMARY
More than 40,000 Kemp's Ridley sea turtles once nested in a single day on one beach in Mexico, but egg collection, oil drilling, development, and commercial fishing extirpated it from the United States by the 1950s. It was listed as endangered in 1970 and was reintroduced to Texas in 1978. There was little progress until 1995. The population reached 199 in 2011. The Mexican population grew from a low of 740 in the mid-1980s to at least 11,600 nests in 2006.

Key deer (Odocoileus virginianus clavium)

Status: EndangeredCritical habitat: none
Listed: 3/11/1967Recovery plan: 5/18/1999
   

Range: FL(b) ---

SUMMARY
Hunting and habitat loss caused the Key deer to decline to about 50 animals by the 1920s. It is currently threatened by car collisions, habitat loss and sea-level rise. After being listed as endangered species in 1967, the Key deer's population decreased from about 400 to about 200 by 1971. It increased relatively steadily since then to 646 in 2001. The 2011 population likely exceeds 800.

Range: FL(m), GA(m), KY(m), MI(b), NC(m), OH(m), PA(m), SC(m), WV(m), WI(b) ---

SUMMARY
Kirtland's warbler declined due to fire suppression suppresse creation of stands of young jack pine, nest parasitism by brown-headed cowbirds, and loss of forest habitat to development and agriculture. It was listed as an endangered species in 1967. In 1971, there were only 201 surviving pairs. In response to habitat protection and restoration, and cowbird control, the population grew steadily to 1,805 pairs in 2011.

Mississippi Sandhill crane (Grus canadensis pulla)

Status: EndangeredCritical habitat: 6/30/1975
Listed: 6/4/1973Recovery plan: 9/6/1991
   

Range: MS(b) --- AL(x), FL(x), GA(x), LA(x), TX(x)

SUMMARY
Less than 2 percent of the Mississippi sandhill crane's wet pine savanna habitat remains. It was to a single population of 40 birds in 1973, threatened by habitat loss, predation, isolation, harassment, contaminants and hurricanes. The release of captive-bred sandhill cranes began in 1981, and the wild population increased from 33 birds in 1989 to 135 birds in 1993. The population has remained relatively steady due to ongoing captive augmentation with 110 birds in 2009 and 2011.

Okaloosa darter (Etheostoma okaloosae)

Status: ThreatenedCritical habitat: none
Listed: 6/4/1973Recovery plan: 10/26/1998
   

Range: FL

SUMMARY
Its restricted range has been reduced by habitat modification and subsequent increases in the brown darter population, habitat degradation due to erosion, and water impoundment [1]. The darter's exact, historic, and current population level is unknown. 1978 estimates ranged from 1,500 to 10,000. The population size doubled between 1995 to 2010, reaching 802,668 fish in 2011.
