  • The Occurrence and Reestablishment of White-Tailed Eagle and Golden Eagle As Breeding Birds in Denmark
    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.

  • 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).

  • Golden Eagle
    A publication by: NORTHWEST WILDLIFE PRESERVATION SOCIETY Golden Eagle Aquila chrysaetos Photograph by Jim Crotty (Flickr) By Jennifer Chow The golden eagle is the largest bird-of-prey in North America, and one of only two eagle species in Canada along with the bald eagle. They are graceful, powerful, swift and agile raptors. Some regard the golden eagle as one of the most formidable birds on Earth. Sightings of this beautiful raptor are rare, but always exciting and memorable. Golden eagles are symbols of freedom and majesty throughout their range. NWPS Headquarters NWPS Vancouver Island t Vancouver 604.568.9160 720-1190 Melville Street PO Box 39058 t Victoria 778.967.3379 Vancouver, BC V6E 3W1 RPO James Bay e [email protected] Victoria, BC V8V 4X8 w www.northwestwildlife.com Characteristics Golden Eagles are dark brown with golden-brown feathers on their head and necks, giving them their namesake; with yellow feet, black claws and beak, and feathers going all the way down to the toes, they are truly an impressive sight. They are large birds measuring 70 to 84cm (28 to 33 inches) in height with a 210 cm (84 in) wingspan. Females are typically larger than males, with females weighing 5 kg (11 lbs) and males slightly less. Other than the size difference, males and females look alike. Their feathers actually weigh more than their bones and golden eagles can have around 7,000 feathers! Very young chicks are covered in a white down, with dark feathers as they grow in. Young golden eagles have defined white patches at the tail base and in the wings for the first few years.

  • Golden Eagle (Aquila Chrysaetos)
    Golden Eagle (Aquila chrysaetos) NMPIF level: Biodiversity Conservation Concern, Level 2 (BC2) NMPIF assessment score: 12 NM stewardship responsibility: Low National PIF status: No special status New Mexico BCRs: 16, 18, 34, 35 Primary breeding habitat(s): Cave/Rock/Cliff (often mountain canyons near open grassland or shrubland) Other Habitats used: Widespread foraging across multiple habitat types Summary of Concern Golden Eagle is a widespread raptor of Europe, Asia, and North America. Although trends appear stable, this species is vulnerable due to its relatively small population size and various sources of mortality, including habitat loss or degradation. Associated Species Ferruginous Hawk (SC1), Red-tailed Hawk, Peregrine Falcon (BC1), Prairie Falcon (SC2), White-throated Swift (SC2), Common Raven Distribution Golden Eagles breed across a great range of latitudes in North America, from the Brooks Range in Alaska south to central Mexico. The species also breeds in Europe and Asia. In the United States, Golden Eagle is resident in all western states, with a breeding range extending east into the Great Plains. United States populations increase in winter with the arrival of migrants from northern breeding areas. In New Mexico, Golden Eagles breed locally in suitable habitat throughout the state (Kochert et al. 2002, Parmeter et al. 2002). Ecology and Habitat Requirements During the breeding season, Golden Eagle occurs primarily in areas of mountain cliffs or canyons. In the west, it is often associated with rimrock terrain adjacent to open desert or grassland areas. Suitable nesting sites may exist within a variety of surrounding habitats, from desert to mountain areas, although dense forests tend to be avoided.

  • Eagle Conservation Plan Guidance Module 1 — Land-Based Wind Energy
    U.S. Fish and Wildlife Service Eagle Conservation Plan Guidance Module 1 – Land-based Wind Energy Version 2 Credit: Brian Millsap/USFWS U.S. Fish and Wildlife Service Division of Migratory Bird Management April 2013 i Disclaimer This Eagle Conservation Plan Guidance is not intended to, nor shall it be construed to, limit or preclude the Service from exercising its authority under any law, statute, or regulation, or from taking enforcement action against any individual, company, or agency. This Guidance is not meant to relieve any individual, company, or agency of its obligations to comply with any applicable Federal, state, tribal, or local laws, statutes, or regulation. This Guidance by itself does not prevent the Service from referring cases for prosecution, whether a company has followed it or not. ii EXECUTIVE SUMMARY 1. Overview Of all America’s wildlife, eagles hold perhaps the most revered place in our national history and culture. The United States has long imposed special protections for its bald and golden eagle populations. Now, as the nation seeks to increase its production of domestic energy, wind energy developers and wildlife agencies have recognized a need for specific guidance to help make wind energy facilities compatible with eagle conservation and the laws and regulations that protect eagles. To meet this need, the U.S. Fish and Wildlife Service (Service) has developed the Eagle Conservation Plan Guidance (ECPG). This document provides specific in‐depth guidance for conserving bald and golden eagles in the course of siting, constructing, and operating wind energy facilities. The ECPG guidance supplements the Service’s Land‐Based Wind Energy Guidelines (WEG).

  • Golden Eagle Pointers
    Golden Eagle Pointers Golden eagles winter in the blufflands of southeast Minnesota, western Wisconsin and northeast Iowa. Although these elusive raptors can be tougher to find than bald eagles that also winter in the Mississippi River valley, taking the time in the right habitat and knowing what to look for can improve your chances. Here are some tips from National Eagle Center Education Director and Golden Eagle Project Co-­‐coordinator Scott Mehus for finding and identifying golden eagles. Distinguishing golden eagles in flight • Raptors seen in the winter months with a DIHEDRAL (V) should stop traffic! That raptor could be an unseasonably late or early Turkey Vulture, eagle, wintering golden rough-­‐legged hawk or Northern Harrier, all birds worth getting out to see! About 80 % of the time when I observe a Golden in a full soar I see it al. using a slight dihedr Definitely not as pronounced as a Turkey Vultures classic dihedral, but much more ld than the Ba Eagles’ flat as a board profile. • Notice the almost headless appearance a of golden eagle. Obviously it is not headless, but the projecting head is e about on third the length of it’s tail and when compared with seeing ald a b eagle overhead, which has as much head projecting out ail in front as there is t sticking out behind, this gives the golden eagle an almost headless appearance. • Notice that wings pinch in at the body along the trailing edge of the wing.
