Golden eagles in North America occur in greatest numbers from Alaska southward throughout the mountain and intermountain regions of the West and into Mexico. Bald eagles have a similar range but tend to be most common near the seacoasts and other large bodies of water. Bald eagles seem to prefer timbered areas along coasts, large lakes, and rivers, but they also occupy other areas. Eagles often abandon habitat that is subject to intensive human activity and move to more remote areas. Although regional and seasonal differences in food habits exist, golden eagle prey consists mostly of small mammals such as jackrabbits, cottontails, prairie dogs, and ground squirrels.
Golden eagles sometimes attack large mammals; deer and pronghorns of all ages have been observed being attacked or killed by eagles.
Eagle courtship displays consist of a series of a€?roller coastera€? dives and other aerial maneuvers. Bald eagles seem less antagonistic to other nesting pairs, and their nesting territories, typically near water, may be much smaller. Not all eagle eggs hatch, and the death rate of young eagles, as in other birds of prey, is high.
Illegal shooting, chemicals, trapping, and power line electrocutions account for a large number of eagle fatalities. Juvenile golden eagles leave the nesting territory as early as May in the Southwest and as late as October or November in the North.
Bald eagles usually are found in coastal areas, along lakes and rivers, and on mountain ridges.
Bald eagles will winter as far north as open water and food are available, migrating out of more northerly nesting areas. Research indicates that golden eagles are maintaining static populations in areas undisturbed by humans. Current population survey information indicates a sizable and healthy population of golden eagles in the western states. Bald eagles occur across the continent from northern Alaska to Newfoundland, and south to southern Florida and Baja California.
Eagles seize small lambs and kids anywhere on the head, neck, or body, frequently grasping from the front or side.
Eagles skin out carcasses, turning the hide inside out while leaving much of the skeleton intact, with the lower legs and skull still joined to the hide. Larger carcasses heavily fed on by eagles may have the skin turned inside out with the skull, backbone, ribs, and leg bones left intact, but with nearly all flesh and viscera missing.

With 23 young chickens all the same age, it’s been a lot easier to tell the girls and boys apart with this hatch. Most of our chicks are barnyard mutts and Easter Eggers (also technically mutts), which can be especially difficult to sex because they have a lot of variation in appearance. Luckily, it looks like we got males AND females from most of our known crosses, so I have a decent basis for comparison this time.
In commercial hatcheries, they use vent sexing (or squeezing the chick and peeking inside its egg-hole, if you want to be scientific about it.) This is difficult to do and requires a lot of specialized training, and has about a 10% error rate even so. A big difference between cockerels (young roosters) and pullets (young hens) is the fighting. The fighting’s never been violent, mostly just show, but Cashew did get it handed to him one morning when he tried to challenge one of the older hens. And I should also mention that the boys don’t always fight, particularly if they have an overbearing mother hen keeping them in line. But at this point, 12 weeks in, even the friendlier cockerels are starting to get a little more standoffish. Female rose combs and pea combs tend to be much smaller and flatter than their male counterparts. All 4 of our hatchery pullets (2 Silver Laced Wyandottes and 2 Light Brahmas) have had pink in their combs from day 1, so don’t read too much into color early on. In addition to watching comb growth, you can also get hints from the coloring as the birds start getting their adult feathers (at about 4-6 weeks.) To me, this is the most interesting part of the guessing game.
Easter Eggers in particular have a few patterns between the sexes that, while not universal, seem to be common among a lot of mixes (and even birds of other species). In general, if an Easter Egger starts feathering out in a silver (black and white) pattern it’s probably a cockerel.
One very obvious sign of an Easter Egger rooster is a chicken with red patches on the wings. We got 3 birds from our Easter Egger x Rhode Island Red cross, two of which were obvious roosters from about 4 weeks on. The boys, Cashew and Sweet-N-Sour, have patches of solid red feathers and iridescent green tail feathers coming in. At first, Crispy feathered out in an even orange-and-brown pattern and I called pullet because of the tiny comb. Our Speckled Sussex + Easter Egger crosses also showed a lot of dark, mahogany red from their father. The adult feathers for both sexes show a lot of red, but the boys have a lot of black on their chests while the girls have red chests. While the article is interesting and makes some really good points, it does have some errors as it is presenting barnyard mixes (hybrids of hybrids…or mutts) rather than 1st generation hybrids. Anytime you have a 2nd generation hybrid (hybrid of a hybrid) the gene pool expands further and a lot of different things can happen. Just a BTW…some overall good photos and descriptions of barnyard mixes and growth patterns, but not overall accurate to all points.
They’ve barely been in the ground a day, but our little solanum berries are already setting fruit!
The Third-age melee set is made by exchanging a Third-age full helmet, Third-age platebody, Third-age platelegs, and Third-age kiteshield with a Grand Exchange clerk.


The set as a whole can no longer be bought or sold on the Grand Exchange, although you can still buy the pieces individually. It was long thought that the chances of obtaining a piece of third-age armour was of about 1 in 10,000 (according to Paul Gower), and in 2010 Mod Maylea stated that the odds are lower than 1 in 100,000 [1]. The third-age melee set is currently the most expensive of the third-age armour sets but is still less expensive than the newer third-age prayer set. When hatched, eaglets have thick, light-colored down that is replaced with dark feathers within 5 to 6 weeks. Birds in their first year are predominantly dark brown, with considerable areas of white on the underside of their wing flight feathers.
Juvenile bald eagles generally are mottled brown or nearly black and resemble adult golden eagles.
They occur in lower numbers to the east across Canada, the Great Lakes states, and the Appalachian Mountains of the eastern United States. Golden eagles seem to prefer the rough broken terrain of foothills and mountains, valleys, rimrocks, and escarpments. They readily adapt, however, to preying on waterfowl, other birds, rabbits, and other small mammals. These characteristic maneuvers may be seen nearly any time of the year, but are most common just before and during the late winter breeding season. Young eagles are antagonistic toward each other and the stronger often kills or causes the weaker to die of starvation. Injuries resulting from accidents such as flying into power lines or being hit by vehicles while feeding on road-killed animals also occur. Many of the golden eagles that breed in the northern United States and Canada migrate south for the winter. Returns from banded bald eagles indicate that birds that nest in Florida often migrate to the northeastern states and southern Canada in midsummer and return in early fall. The current breeding population for 17 western states is estimated at 17,000 to 20,000 breeding pairs. In 1989, the breeding population of bald eagles in the continental United States (excluding Alaska) was estimated to be about 2,673 pairs. Both species readily feed on livestock carrion and carcasses left by foxes and coyotes, although some individuals prefer live prey to carrion.
They usually kill adult animals, or lambs and kids weighing 25 pounds (11 kg) or more, by multiple talon stabs into the upper ribs and back.
On very young animals, however, the ribs often are neatly clipped off close to the backbone and eaten. Schartz, Wildlife a€” Drawings, 1980, Missouri Department of Conservation, Jefferson City, p. But we won’t know for certain until they crow or lay an egg (probably at least another 6 weeks).
There are plenty of resources on feather sexing out there, but the general process involves comparing the relative length of the primary and covert feathers on the wing at about one week of age.
Pullets will occasionally chest bump or peck each other, or even engage in battle with the boys sometimes as the pecking order gets sorted out — the Brahmas were the biggest chicks at first, so there were a few scuffles as the boys passed them in rank. That was a big part of why I was able to explain away so many rooster traits last time around. If a silver EE starts to get patches of red on its wings and shoulders, like FiveSpice in the photo above, it’s definitely a cockerel. They have barred (striped) feathers like Barred Rocks, but peacombs and puffy cheeks like EEs.
But then I saw red patches start to leak in on the wings and shoulders, and changed my vote to cockerel. They looked nearly identical for the first few weeks, with white speckling (also from their father) on their juvenile feathers. Just like red spots on the wings, black chest feathers on an EE almost always indicate a cockerel.
We have an 8 week EE that I was starting to suspect was a cockerel, but now I think still odds are it is a pullet. I have had them for a week and when I first got them I thought all hens and now I have been told I may have all roosters. One of the main reasons this armour costs so much is because of the rarity of the reward while doing a level 3 Treasure Trail. However, a livestream with Mod Simon and James revealed the mechanics of Treasure Trail rewards in detail[2], meaning the actual chances could be calculated: approximately 1 in 16,896 per item roll for any of the 12 parts of third-age equipment, or approximately 1 in 202,752 for a specific part, per item roll - with an average of 5 item rewards per Trail, this gives approximately 1 in 3,380 for any part, or 1 in 40,551 for a specific part, per Trail completed. By far the greatest concentration of bald eagles is in Alaska, along large rivers and the coast. Nesting pairs or concentrations of juvenile birds can be a major cause of predation on local game bird populations.
Experiments indicate that without wind to assist them even large eagles cannot take off from flat ground with more than 5 or 6 pounds (2 to 3 kg) in their talons.
Aerial displays made during other seasons may serve to identify territorial boundaries and maintain pair bonds between adults. The same nests may be used several years, becoming larger as new material is added each year. Both adults hunt and secure food for the young, with the female doing most of the incubating, feeding, and brooding. Losses due to exposure, diseases, parasites, and predation occur while the young are still in the nest. They arrive in the southwestern United States as early as October and reach peak numbers in December and January in Texas and February and March in New Mexico before migrating back north.
Returns from birds banded in Saskatchewan indicate that some move as far south as Texas and Arizona.
Information indicates a slight decline in the western population as a whole, with drastic declines in some specific areas associated with increased human activity.


Eagles are efficient predators and can cause severe losses of young livestock, particularly where concentrations of eagles exist. On animals the size of small lambs and kids, fewer than four talon wounds may be found, one made by the hallux and one or two by the opposing talons. Their feet and talons are well adapted to closing around the backbone, with the talons puncturing large internal arteries, frequently the aorta in front of the kidneys. Eagles frequently do not eat the breast bone, but some clip off and eat the lower jaw, nose, and ears.
Eagles may defecate around a carcass, leaving characteristic white streaks of feces on the soil.
But in general, the girls make their point and move on, while the boys make an event of it.
FiveSpice and Sesame are very common EE patterns, so I felt pretty sure of their sex by the time they were fully feathered out. But, this gets a little tricky when the birds have a red breed mixed in, as was the case with our Easter Eggers crossed with Speckled Sussex and Rhode Island Red.
These feathers have been replaced with adult feathers over the last few weeks, and the speckling has disappeared. You have to look at overall growth, color, but in particular comb color and size, which I find seems to be the most telling and reliable. The hen must be barred while the rooster MUST be non-barred for the black sex-linking to work.
I stumbled upon this worrying that my week old EE may be a cockerel (if so I will have to rehome as I live in city limits).
Players can exchange this set with a Grand Exchange clerk to receive the items listed above. The tarsi (lower legs) are feathered to the toes on golden eagles but are bare on bald eagles (Fig. The back of the neck may or may not appear gold or bronze, depending upon light conditions and the individual bird. Their tail and wings are mottled brown and white on the underside in contrast to the characteristic white patches under the wings and the white-banded tail of juvenile golden eagles.
However, attacks on animals that weigh more than 30 to 40 pounds (14 to 18 kg) are uncommon. At times, some may prey repeatedly on domestic sheep and goats, primarily young lambs and kids. Eagles flying into the wind and taking prey from hillsides, however, sometimes carry animals of twice those weights for considerable distances. Up to 75% of the young eagles die during their first year due to starvation, disease, and causes directly or indirectly associated with humans. After the nesting season, they may congregate in areas where food is more readily available, and then large numbers may roost in the same tree.
Golden eagles also winter in parts of Alaska, Canada, and Mexico; however, the number in this latter group would not likely exceed 10,000 birds. The nationwide January eagle count sponsored by the National Audubon Society indicated about 3,700 birds each year from 1961 through 1966. Generally, they prey on young animals, primarily lambs and kids, although they are capable of killing adults.
Talon punctures typically are deeper than those caused by canine teeth and somewhat triangular or oblong. The major cause of death is shock produced by massive internal hemorrhage from punctured arteries or collapse of the lungs when the rib cage is punctured. And then, as the rest of Crispy’s adult feathers started to come in, I realized that the red was coming in all over and in a very consistent pattern. I find you cannot even compare 2 sibling mutts to each other as you could with pure breeds or the 1st generation hybrid as so much variation can happen…with mutts the best thing is to watch and wait. Although adult bald eagles of both sexes have the white head and tail, they do not develop these characteristics until they are 4 to 5 years of age or older (Figs. Where golden eagles prey on domestic animals, they usually take lambs and kids, but some become persistent predators of domestic livestock as large as 500 pounds (227 kg). The nesting territory of golden eagles varies from about 3 to 65 square miles (8 to 168 km2) per pair. Golden eagles breeding in the more temperate climates south of Canada often remain in the same region year-round. The annual midwinter counts coordinated by the National Wildlife Federation since 1979 have ranged from about 9,000 birds to more than 13,000 in the contiguous 48 states. Crushing between the wounds usually is not found, although compression fractures of the skulls of small animals may occur from an eaglea€™s grip. Eagles also may simply seize young lambs, kids, or fawns and begin feeding, causing the prey to die from shock and loss of blood as it is eviscerated.
They may clean all major hemorrhages off the skin, leaving very little evidence of the cause of death, even though there may be many talon punctures in the skin.
Although the young are as large as the adult birds at this time, their parents may continue to provide them with food and protection for as long as 3 months after they leave the nest. Many northern golden eagles migrate through areas occupied by resident eagles to areas farther south. Evaluation of golden eagle predation on domestic sheep, Temperance Creek Snake Sheep and Goat Allotment, Hells Canyon National Recreation Area, Oregon.
The 1989 count does not represent a comprehensive national count, so it is not directly comparable to earlier counts.
These January counts indicated four areas of greatest abundance nationwide: the upper half of the Mississippi Valley, the Northwest (Washington, Oregon, Idaho, and Montana), Florida, and the Chesapeake Bay area.
