Despite regulations on their usage, lead and mercury poisonings were found to be the cause of death of 61 white-tailed eagles found in Germany from 1993 to 2000. In order to offset the numerous chemical and metal based poisoning that humans were inadvertently exposing the species to, a widespread operation was undertaken to feed white-tailed eagles uncontaminated foods in Sweden. Here, carcasses from slaughterhouses placed in areas free of human disturbance, usually

text: Technical Bulletin. In 1984, the National Wildlife Federation listed hunting, power-line electrocution, and collisions in flight as the leading causes of eagle deaths. Bald eagles have also been killed by oil, lead, and mercury pollution, and by human and predator intrusion at nests. The species was first protected in the U.S. and Canada by the 1918 Migratory Bird Treaty, later extended to all of North America. The Bald and Golden Eagle Protection Act, approved by the U.S. Congress in 1940, protected the bald eagle and the golden eagle, prohibiting commercial trapping and killing of the birds. The bald eagle was

If an eagle has blood levels of lead above 60μg/dL then it is considered to be a clinical case and the chances of the eagle surviving at this point are very slim to none. The liver and bone can also be biopsied to test for lead toxicity though this can only occur after the eagle has already died. Birds can also be x-rayed, as any larger pieces of lead consumed will be visible on it. When treating patients experiencing lead poisoning, the goals are

D12 hatched on March 27, branched on June 9 and had fledged on June 13. Authorities believe the cause of death was electrocution. After Raptor Resource Project leaders notified the power company, crews showed up to address the safety concerns by installing a temporary insulation shield on the poles in the area. While power lines are not an electrocution hazard for birds, older poles that are

An early natural history video depicting a cougar ("Puma concolor") ambushing and killing an immature bald eagle feeding at a rabbit carcass is viewable online although this film may have been staged. Most non-human-related mortality involves nestlings or eggs. Around 50% of eagles survive their first year. However, in the Chesapeake Bay area, 100% of 39 radio-tagged nestlings survived to their first year. Occasionally, nestling or egg fatalities are due to nest collapses, starvation, sibling aggression or inclement weather. Another significant cause of egg and nestling mortality

Lastly, majority of farmers and ranchers often will shoot bald and golden eagles that they consider a threat to their livestock. Unfortunately, many assumptions are made about the bald and golden eagles, thinking they are a harmful. The two eagles seek for dead animals that are killed from other factors. The measures that were taken to protect bald and golden eagles such as the 1940 Bald and Golden Eagle Protection Act, banning of DDT in 1972, the Bald

In this study, 68% of mortality was human-caused. Today eagle-shooting is believed to be considerably reduced due to the species protected status. In one case, an adult eagle investigating a peregrine falcon nest for prey items sustained a

Jancita Eagle Deer Jancita Eagle Deer (1952 – April 4, 1975) was a Brulé Lakota who lived on the Rosebud Indian Reservation in South Dakota. She was notable for accusing William Janklow of having raped her in January 1967 when he was a poverty lawyer and Director of the Rosebud Sioux Legal Services program on the reservation. She had worked as his babysitter. At the time the Bureau of Indian Affairs (BIA) and the Federal Bureau of

In southern Idaho, 10 out of 17 golden eagles examined were found to have had exposure to lead. Golden eagles did not prove as susceptible to poisoning from the pesticide DDT as other large raptors, probably because of their diet of mammals. Eggs from golden eagle nests that were collected after 1946 in North America had shell thicknesses similar to (less than a 10% difference) those collected in earlier years. However, in Scotland egg shell thickness did decrease by around

Avian cholera caused by bacteria ("Pasteurella multocida") infects eagles that eat waterfowl that have died from the disease. The protozoan "Trichomonas" sp. caused the deaths of 4 fledglings in a study of wild golden eagles in Idaho. Several further diseases that contribute to golden eagle deaths have been examined in Japan. A captive eagle died from two malignant tumors – one in the liver and one in the kidney. In December 2016, the U.S. Fish and Wildlife Service proposed allowing wind-turbine electric

In the 1980s, California ground squirrels, considered agricultural pests, were poisoned by the anticoagulant rodenticide, Chlorophacinone. In turn, the poisonings caused golden eagles, as one of the major natural predators of California ground squirrels, to die in turn. At least 10 individuals died in 1971 from eating Thallium(I) sulfate–laced pronghorn set out by sheep ranchers in Wyoming; despite public outcries, poisoning by sheep ranchers continued into the 1980s.

By 1919, the spent lead pellets from waterfowl hunting was positively identified as the source of waterfowl deaths. Lead shot has been banned for hunting waterfowl in several countries, including the US in 1991 and Canada in 1997. Other threats to wildlife include lead paint, sediment from lead mines and smelters, and lead weights from fishing lines. Lead in some fishing gear has been banned in several countries.

However, golden eagles are occasionally targeted as well for the same reasons. The main cause of mortality for golden eagles in Britain has been poisoning, 51 eagles have been verified to be killed by poisoning from 1980 to 2008 but the actual number killed is probably higher. A disproportionate amount of golden eagle poisonings in Scotland from 1981 to 2000 were linked to grouse moors (where grouse are kept for the pleasure of shooting) and were probably caused by gamekeepers deliberately

Lead, one of the leading causes of toxicity in waterfowl, has been known to cause die-offs of wild bird populations. When hunters use lead shot, waterfowl such as ducks and other species (swan especially) can ingest the spent pellets later and be poisoned ; predators that eat these birds are also at risk. Lead shot-related waterfowl poisonings were first documented in the US in the 1880s. By 1919,

Of natural sources of death, starvation is probably under-reported. 11 of 16 dead juvenile eagles which had hatched in Denali National Park had died of starvation. Of 36 deaths of golden eagles in Idaho, 55% were possibly attributable to natural causes, specifically 8 (26%) from unknown trauma, 3 (10%) from disease and 6 (19%) from unknown causes.

text: Lead poisoning in raptors Lead poisoning is a significant health issue affecting the raptor population, amongst other species. Without rehabilitation, many raptors will succumb to the symptoms of lead poisoning once affected. While the general public may not know how they are possibly contributing to the problem, nearly 100% of lead poisoning can be prevented if humans paid close attention to their hunting and angling practices. There are two major contributors to these avian species being affected by lead poisoning and they are through hunters using lead ammunition, or through anglers using lead tackles. When hunters shoot an animal, they

It has been shown that essentially all animals that have been shot with lead contain lead fragments in them. One singular standard 150-grain lead bullet has the ability to kill up to 10 eagles. One study noted that of 38 deer carcasses examined, over 74% of them contained over 100 lead fragments from one bullet. From the point of entry of a bullet into an animal, these small fragments can travel up to into the carcass.
