What Is This Species Conservation Status
Fortunately, golden eagles not listed as a species at risk in Canada. In Ontario, the species is listed as endangered on the Species at Risk in Ontario List under the Endangered Species Act.
Golden eagle populations are threatened by the poisoning of prey through toxic chemicals or lead as a by-product from hunting, collisions with vehicles, wind turbines and other structures, as well as electrocution from power poles.
Early Diversity Of Bird Ancestors
The first large, diverse lineage of short-tailed avialans to evolve were the , or “opposite birds”, so named because the construction of their shoulder bones was in reverse to that of modern birds. Enantiornithes occupied a wide array of , from sand-probing shorebirds and fish-eaters to tree-dwelling forms and seed-eaters. While they were the dominant group of avialans during the Cretaceous period, enantiornithes became extinct along with many other dinosaur groups at the end of the era.
Many species of the second major avialan lineage to diversify, the , were semi-aquatic and specialised in eating fish and other small aquatic organisms. Unlike the Enantiornithes, which dominated land-based and arboreal habitats, most early euornithes lacked adaptations and seem to have included shorebird-like species, waders, and swimming and diving species.
The latter included the superficially -like and the , which became so well adapted to hunting fish in marine environments that they lost the ability to fly and became primarily aquatic. The early euornithes also saw the development of many traits associated with modern birds, like strongly keeled breastbones, toothless, beaked portions of their jaws . Euornithes also included the first avialans to develop true and a fully mobile fan of tail feathers, which may have replaced the “hind wing” as the primary mode of aerial maneuverability and braking in flight.
What Does It Eat
The golden eagles diet is extremely varied. While they typically hunt small mammals, such as rabbit, hare, ground squirrel, prairie dog and marmot, these fearsome predators can also kill larger prey, including crane, swan, deer, seal, mountain goat, bighorn sheep, pronghorn, coyote, badger and bobcat. These raptors search for prey while soaring high in the sky, flying close to the ground or from a perch. Once theyve spotted their potential prey, they use their talons to capture it. Golden eagles also feed on carrion, catch fish, steal from nests and take food from other birds.

How Rare Is It To See A Golden Eagle
Though protected, golden eagles are not a threatened or endangered species. Populations are stable and their habitat is wide-ranging, but it is still quite rare to see one. This raptor prefers to stay away from people, sequestering itself in the wilder regions of its range.
The chances of observing a golden eagle are higher in Alaska, Canada, and the western United States, where they are more common. Keep an eye out for one hunting amongst agricultural areas or open grasslands, or use binoculars to observe cliff lines and treetops more closely where a nest could be.

Peregrine falcons are making a comeback in southeastern Michigan, according to the Michigan Department of Natural Resources. The birds became endangered in the mid-20th century because of pesticides like DDT. But now, the population has grown from near extinction to 15 nesting pairs in southeast Michigan alone.
Where Do Golden Eagles Live In The Winter
Wintering grounds for the golden eagle in North America include most of the lower 48 states, southern Canada, and Mexico. Populations that spend the summer in northern Canada and Alaska typically migrate south to Midwestern and Northeastern states. In Eurasia, golden eagle populations generally winter in or near their breeding grounds.

Dinosaurs And The Origin Of Birds
et al.
Based on fossil and biological evidence, most scientists accept that birds are a specialised subgroup of and, more specifically, members of , a group of theropods which includes and , among others. As scientists have discovered more theropods closely related to birds, the previously clear distinction between non-birds and birds has become blurred. Recent discoveries in the Province of northeast China, which demonstrate many small theropod , contribute to this ambiguity.
The consensus view in contemporary is that the flying theropods, or , are the closest relatives of the , which include dromaeosaurids and . Together, these form a group called . Some members of Deinonychosauria, such as , have features which may have enabled them to glide or fly. The most basal deinonychosaurs were very small. This evidence raises the possibility that the ancestor of all paravians may have been , have been able to glide, or both. Unlike Archaeopteryx and the non-avialan feathered dinosaurs, who primarily ate meat, recent studies suggest that the first avialans were .
Classification Of Bird Orders

The classification of birds is a contentious issue. and ‘s Phylogeny and Classification of Birds is a landmark work on the classification of birds, although it is frequently debated and constantly revised. Most evidence seems to suggest the assignment of orders is accurate, but scientists disagree about the relationships between the orders themselves evidence from modern bird anatomy, fossils and DNA have all been brought to bear on the problem, but no strong consensus has emerged. More recently, new fossil and molecular evidence is providing an increasingly clear picture of the evolution of modern bird orders.

Golden Eagle Facts Golden Eagle Habitat Golden Eagle Diet
This article validates critical golden eagle facts. The Golden Eagle is a large sized bird of prey that largely inhabits in the Northern Hemisphere. Golden eagles breed all throughout North America, Africa and Eurasia. They are extensively found in the Alameda County, California. Like other raptors, these eagles are also aggressive especially toward the one who attempts to approach their nests.
Golden eagle is the national bird of Kazakhstan, Germany Austria, Mexico, and Albania. Few of these countries have golden eagle coins in which the golden eagle pictures are embedded. These eagles do have some cultural significance in that most of the Native Americans give a high value to the golden eagle feathers because of their own spiritual association with these species.
What Is Ncc Doing To Conserve Habitat For This Species
The Nature Conservancy of Canada owns several properties across the country where golden eagles have been observed during the breeding season and migration. Many of these properties are large, connected tracts of natural habitat, which provide the basic necessities for these large predators.
In Alberta, golden eagles can be found on many NCC properties throughout the province, such as Sandstone Ranch in the Milk River Ridge Natural Area, the Frayn property in Crowsnest Pass Natural Area, as well as the Waldron Conservation Project located in the Southern Foothills Natural Area. In Manitoba, NCC has partnered with the Manitoba government to expand Pembina Valley Park and also owns Jiggens Bluff II, a part of the Oak Lake/Plum Lakes Important Bird Area . NCC also manages eight properties in Rainy Lake to Lake of the Woods Natural Area, where golden eagles have been observed.
In Saskatchewan, golden eagles can be seen on NCCs Old Man on His Back Heritage and Conservation Area, a property consisting of prairie grasslands, as well as properties in the Cypress Uplands and Missouri Coteau Natural Areas.

What Do They Look Like
Golden eagles are North America’s largest predatory bird. They are dark brown raptors with long, broad wings. Their length ranges from 70 to 84 cm, and their wingspan ranges from 185 to 220 cm. Males and females look similar, but females are much larger than males. Females weigh from 3940 to 6125 g. Males weigh from 3000 to 4475 g. Adults are mostly dark brown. They have a grayish brown tail and golden brown on their heads. Adults have dark brown eyes. Their bills and claws are black and their ceres and feet are yellow. Their legs are covered in feathers all the way down to the toes.
Juvenile golden eagles look similar to adults, but they have light patches on the tips of their wings, and a wide white band on their tails. They begin to look like adults when they are 4 to 6 years old.
There are 5 or 6 subspecies of the golden eagle. Only one subspecies, Aquila chrysaetos canadensis is found in North America.

What Is The Golden Eagle Range
Golden eagles in North America do not occupy a continuous range but have split ranges in western and eastern North America. Most golden eagles live in the west, while a small number live in the East.
The range of eagles in the west is huge and expands and contracts throughout the year. Western Eagles are composed of residents, short-distance, and long-distance migrants. These movements result in a highly mobile overall population occupying and vacating parts of their western through an annual cycle.
Interestingly, most golden eagles in the east are migratory. Nearly all adult golden eagles migrate north to breed in Northern Canada and return to spend the winter or nonbreeding months in relatively warmer regions of southern Canada and the northern United States.
What Is The Distribution Range Of The Golden Eagle
The golden eagle has a broad range distribution, primarily occurring between latitudes 20° to 70°N, with some populations reaching farther south. The eagles’ primary range includes North America, Europe, and Asia.
Golden eagles in North America have breeding grounds throughout the Canadian provinces and Alaska. They are also common year-round residents in the Western United States and northern Mexico. These birds can be found throughout the lower 48 states during winter, as birds from Canada migrate south to the eastern half of the US.
Eurasian golden eagle populations are generally permanent residents throughout their range. The eagle occurs across most of northern Europe, east through Siberia and the Kamchatka Peninsula. Golden eagles also occur in southern Europe, central and south Asia, and North Africa. One population is known to reside as far south as the Bale Mountains of Ethiopia.

Types Of Eagles What Do Eagles Eat Where Do Eagles Live
Not many of you would be aware of these types of eagles . This article lays down some of the important facts about different eagle species. Eagles are one of the largest birds of prey that belong to the family of Accipitridae. Most of these species are endemic to Eurasia and Africa out of which bald eagles and golden eagles are the only species that subsides in the North America and Canada only. Eagles generally build their nests on lofty trees in tropical and subtropical forests where water is abundant. Like other raptors, females are slightly larger as compared to males. These are the aggressive birds and do not allow anyone to approach their nests. While they migrate toward north in spring season these birds of prey travel to south in fall in quest for food. They have long eye brows that provides a shade against sunlight. Eagles rarely miss any prey for the reason that they have sharp eyesight and powerful talons that makes the kill almost unmoved.
Where Its Been Found In Ontario
In Canada, Golden Eagles are most common in the western mountains and prairies but are also fairly widespread in Labrador and Quebecs Ungava peninsula.
In Ontario, breeding Golden Eagles are presently known only from the Hudson Bay Lowland, although there is some evidence suggesting they once nested much further south.
Currently there are believed to be 10 to 20 pairs in the province.

When Is Golden Eagle Week
The Scottish town of Moffat has been declared Scotland indeed the UKs first Eagle Town, and its inaugural Golden Eagle Week took place in September 2021.
The festival was organised by the South of Scotland Golden Eagle Project, which recently successfully translocated eight eaglets from the Highlands to the Southern Uplands of Scotland.
The project aims to bolster numbers living in the wild and ultimately restore this magnificent predator to the areas it used to inhabit.

How Do They Reproduce
Golden eagles are monogamous, and pairs may breed together for several years. In sedentary populations, pairs stay together year round. Golden eagle courtship includes the pair flying together, chasing, diving and pretending to attach each other.
- Mating System
- monogamous
Golden eagles breed between March and August. Some golden eagles are sedentary, remaining in the same territory all year. These eagles may begin building their nests and forming pairs as early as December. Migratory golden eagles dont begin pair formation and courtship until they return to the breeding grounds in early spring. Many pairs re-use the same nest for many years. Golden eagles usually build their nests on cliffs, but may also use trees, riverbanks and man-made structures, such as windmills, observation towers, nest platforms, and electrical towers. Nests are built 0 to 107 m off the ground. The male and female both build the nest. This takes 4 to 6 weeks. Nests are made of sticks and lined with soft vegetation, such as grasses, dry yucca leaves, inner bark, dead and green leaves, mosses and lichens. Some golden eagle nests are huge. The largest nest was 6.1 m tall and 2.59 m wide.
