United States Fish and Wildlife Services o Detached Retina (cloudy left eye) Life Expectancy Average Life Span: 28 years The oldest known golden eagle lived to 46 years under managed care Statistics – North America's largest predatory bird. Weight – Females: 8.6-13.5 pounds; males 6.6-9.8 pounds Length: 2.3-2.8 feet; wingspan: 6-7.2 feet Diet Wild – primarily small mammals such as rabbits, hares, ground squirrels, prairie dogs, and marmots. They also eat birds, reptiles and fish in smaller numbers. o Golden eagles occasionally capture large prey, including seals, ungulates, coyotes and badgers. A pair of eagles will often hunt together; one chases the prey to exhaustion, and the other swoops down for the kill. Predators – Golden eagles have few predators. Wolverines and grizzly bears are the only recorded predators of golden eagle nestlings. Habitat Tundra, shrublands, grasslands, woodland-brushlands, and coniferous forests. Most golden eagles are found in mountainous areas, but they also nest in wetland, riparian and estuarine habitats. Region – They occur throughout Eurasia, in northern Africa, and in North America. In North America, golden eagles are found in the western half of the continent, from Alaska to central Mexico, with small numbers in eastern Canada and scattered pairs in the eastern United States. Golden Eagle 3 Aquila chrysaetos Reproduction – Monogamous: may maintain pair bonds for several years. For migratory golden eagles, pair formation and courtship begin when the eagles return to the breeding grounds, between February and mid-April. Courtship activities in this species include undulating flight by one or both members of the pair, chases, dives, mock attacks, presenting talons, soaring together and circling. Golden eagles breed from March through August, depending on their geographic location. The female lays 1 to 4 (usually 2) eggs, with 3 to 4 day intervals between each egg. The female begins incubating after the first egg is laid, and is responsible for most of the incubation, though the male often takes part. Incubation lasts for 35 to 45 days. The chicks are brooded by the female with decreasing frequency for the first 45 days. Both parents bring food to the nestlings. The nestlings begin to leave the nest between 45 and 81 days of age by walking, hopping or falling out of the nest. They begin to fly around 10 weeks of age, and become independent from the parents 32 to 80 days after fledging. Juveniles do not breed until age 4 to 7 years, after attaining adult plumage. Adaptations – Powerful feet and massive, sharp talons to snatch up a variety of prey. Behavior – Solitary or in pairs They can fly up to 80 mph, though the average speed is 28-32 mph, and may reach speeds up to 200 mph in a dive. Conservation Concerns The golden eagle is federally protected under the Bald Eagle Protection Act of 1962. Many golden eagles have been electrocuted in power lines, caught in steel traps set for coyotes and other animals, and poisoned by ranchers. Recreational activities may also disturb breeding, migration and wintering activities. Golden eagles are likely to abandon nests during incubation if they are disturbed.

Anywhere with a permanent supply of food and water source Region Canada through the United States except for Mohave Desert of Nevada and Colorado, Texas, New Mexico and Southern California. Reproduction – Polygynous: having more than one female mate at one time. Breeding takes place in late winter or early spring. Gestation lasts 60-63 days, but the female may delay implantation up to 8 months. North American River Otter 5 Lontra canadensis Females give birth to 1 to 6 young per litter, with an average of 2 to 3, in a den near the water. Pups are cared for solely by the mother until weaned around 3-4 months. At 6 months the pups head off on their own. Adaptations Physical shape made for quick swimming. Long slender bodies, small ears, nostrils that can close underwater, webbed feet and nictitating membranes (clear eyelids for underwater hunting and navigation). ● Sensitive whiskers help detect fish and other prey. The North American River Otter has 2 layers of fur; the first is a thick, dense under layer and a longer over layer of guard hairs that trap air bubbles for insulating while swimming. Their ‘playful’ behavior often serve a larger purpose such as strengthening bonds, improving hunting, or scent marking. Behavior – Territorial They are known as playful animals, exhibiting behaviors such as mud/snow sliding, burrowing through the snow, and water play. Very high metabolism Can stay underwater for up to 8 minutes They normally hunt at night, but can be seen at all times of day. Conservation Concerns Sensitive to pollution so will leave areas with water pollution. They were once extirpated in many areas of their region due to unregulated trapping, habitat destruction, and pollution specifically related to coal, gas, timber and tanning industries. Reintroductions and habitat restoration efforts have been deemed successful increasing the population. Conservation Ask Support Global and Local Conservation Programs o Action – Participate in local conservation and citizen science efforts .

Statistics Weight – 10-38 pounds (Males tend to be larger than females.) Length – Head-Body: 2-3.5 feet; Tail: 2-5 inches Diet – Carnivore Wild – Snowshoe hares, also rodents, birds, and fish. Predators Young kittens are vulnerable to other large carnivores, such as wolves and bears. Hunting by humans is managed through regulated seasons. Habitat Usually mature forests with dense undergrowth, but also rocky areas, or tundra Region Throughout Canada, in western Montana, and in nearby parts of Idaho and Washington. There are small populations in New England, Utah and possibly in Oregon, Wyoming and Colorado. Canada Lynx 7 Lynx canadensis Reproduction – Polygynous: having two or more mates, either simultaneously or successively. The mating system of these animals is not well reported. Females reach sexual maturity at 21 months and males at 33 months. Females enter estrus only once per year, and lasts 1 to 2 days. Mating in February and March. Gestation lasts 8 to 10 weeks. Females give birth to one litter a year, usually in fallen logs, stumps, clumps of timber, or similar tangles of roots and branches. Litters typically have 2 or 3 kittens, though the number may range from 1 to 5. Lynxes weigh less than half a pound at birth. Lactation lasts for 5 months, although kittens eat some meat as early as 1 month of age. Young remain with the mother until the following winter's mating season, and siblings may remain together for a while after separation from the mother. Mothers may help to educate their young in hunting techniques, and cooperative hunting has been observed. Males do not participate in parental care. Adaptations – The paws are quite large and furry, helping to distribute the weight of the animal when moving on snow. Behavior – Nocturnal and solitary Territorial – female home ranges are usually encompassed by the home range of a male, and the home ranges of multiple females may overlap.

  • Bald Eagle Haliaetus Leucocephalus
    Appendix A: Birds Bald Eagle Haliaetus leucocephalus Federal Listing N/A State Listing T Global Rank G4 State Rank S2 Regional Status Photo by Jason Lambert Justification (Reason for Concern in NH) Bald Eagle populations in the conterminous United States entered a severe population decline in the 1950s, largely a result of reproductive failure induced by biomagnification of the insecticide DDT (Buehler 2000). Some regional breeding populations, especially in eastern and southern states, became locally extirpated. This serious decline led to the designation of the bald eagle as Endangered under the Endangered Species Act. Following the banning of DDT and intensive reintroduction efforts, Bald Eagle populations gradually rebounded, and the species was removed from the federal endangered list in 2007. In the Northeast, recovery has been particularly strong since 2000. However, most states still consider Bald Eagle a SGCN due to historic extirpations and historic sensitivity to certain environmental stressors, particularly contaminants. Distribution Bald eagles currently occur and breed in all Lower 48 states and in Alaska. Based upon data provided by state agencies, from a population low of 417 breeding pairs in 1963 the U.S. Fish and Wildlife Service estimated that there were an estimated 1,500 breeding pairs in the contiguous 48 states in 1982 and an estimated 5,300 pairs in the same area in 1997 (derived from data in Buehler 2000), and nearly 9800 breeding pairs in the Lower 48 states in 2006. The USFWS estimated that there were 463 breeding pairs in the six New England states in 2006. The nationwide population has probably increased substantially since 2006, but more recently compiled information is not available from USFWS.

In 1940, Bald Eagle was provided protection under the Bald and Golden Eagle Protection Act 2. In 1966, the southern subspecies was listed as federally endangered under the Endangered Species Preservation Act; the entire population in the contiguous United States was listed as endangered in 1978 under the 1973 Endangered Species Act (ESA). A significant increase in numbers of nesting pairs, productivity, and distribution allowed Bald Eagle to be reclassified from Endangered to Threatened in 1995 under the ESA 3. Bald Eagle was delisted in 2007, and numbers are considered to be stable to increasing across its range 4. The species has been assigned different state conservation ranks by the Wyoming Natural Diversity Database for the breeding season and nonbreeding season because the abundance of the species is different between seasons. NATURAL HISTORY Taxonomy: Bald Eagle is a member of the family Accipitridae, which includes kites, eagles, harriers, and hawks 5. There are two subspecies of Bald Eagle; H. l. alascanus is found north of 40 degrees latitude across North America, including Wyoming, while H. l. leucocephalus is found south of 40 degrees latitude in the Gulf coast states 6.

    The occurrence and reestablishment of White-tailed Eagle and Golden Eagle as breeding birds in Denmark Erik EhmsEn, LEnnart PEdErsEn, hans meltoftE, tschErning cLausEn & timmE nyEgaard (Med et dansk resumé: Forekomst og genetablering af Havørn og Kongeørn som danske ynglefugle) Abstract Except for a number of largely unsuccessful breeding attempts during the second half of the 20th century, the White-tailed Eagle Haliaeetus albicilla had been absent as a breeding bird in Denmark for more than 80 years, when a popu- lation established itself during the second half of the 1990s. Released from persecution and contaminants the population has grown to 37 pairs in just 16 years. Reproductive success has grown with age and experience of the birds, so that the average number of fledged young per breeding pair peaked with almost two per pair 8-10 years after the establishment of each breeding pair. Similarly, the Golden Eagle Aquila chrysaetos reestablished a small population in Denmark from 1999 onwards after probably having bred here until about 150 years ago. For both species, this success was facilitated by conservation efforts including protection zones around eagle nests, monitoring and public outreach mainly carried out by volunteers from the Danish Ornithological Society / BirdLife Denmark.

Because sea otters (Enhydra lutris) exert a wide array of direct and indirect effects on coastal marine ecosystems throughout their geographic range, we investigated the potential influence of sea otters on the ecology of Bald Eagles (Haliaeetus leucocephalus) in the Aleutian Islands, Alaska, USA. We studied the diets, productivity, and density of breeding Bald Eagles on four islands during 1993–1994 and 2000–2002, when sea otters were abundant and scarce, respectively. Bald Eagles depend on nearshore marine communities for most of their prey in this ecosystem, so we predicted that the recent decline in otter populations would have an indirect negative effect on diets and demography of Bald Eagles. Contrary to our predictions, we found no effects on density of breeding pairs on four islands from 1993–1994 to 2000–2002. In contrast, diets and diet diversity of Bald Eagles changed considerably between the two time periods, likely reflecting a change in prey availability resulting from the increase and subsequent decline in sea otter populations.

  • The Eagle Huntress Ancient Traditions and New Generations
    1 The Eagle Huntress Ancient Traditions and New Generations By Adrienne Mayor [email protected] May 1, 2016 "The sight of a Eurasian nomad hunting with swift horse, loyal dog, and powerful golden eagle is a majestic scene with ancient roots. For thousands of years this was how the nomadic peoples of the northern steppes from the Caucasus to Manchuria hunted for survival. " This is a revised and expanded version of the two-part article that appeared April 5-6, 2016 online at ancient-origins.net and reprinted April 18, 2016 http://bust.com/feminism/16147-the-untold-history-of-the-eagle-huntress.html "A fast horse and a soaring eagle are the wings of a nomad." --Kazakh proverb 2 FIG 1. Kazakh eagle hunter (Shutterstock) Falconry, training raptors to hunt for game, is particularly suited to vast grasslands especially in combination with horses and dogs. The earliest images of falconry appear in Assyrian and Hittite reliefs of the 9th and 8th centuries BC. Classical Greek and Roman authors Ctesias, Aristotle, Pliny, and Aelian described falconry. A Persian textile (10th century AD) depicts the Banu (Lady Governor) of Rayy (ancient Rhages, near Tehran, northern Iran) riding with her falcon. In AD 1270 Marco Polo described how the nomads of Central Asia hunted on horseback with small falcons, hawks, and eagles. FIG 2. Banu (Lady Governor) of Rayy, Persian textile, 10th century AD 3 For thousands of years, golden eagles have been the favorite raptor to train as a hunting companion across the northern steppes from the Caucasus to China. Eagles are strong predators especially adapted to winter hunting for hare, marmot, wild goat, deer, fox (even lynx, pallas cat, and wolf, although these are unnatural prey and dangerous for the eagles).
