How to Tell a Juvenile Golden Eagle from a Juvenile Bald Eagle

How to Tell a Juvenile Golden Eagle from a Juvenile Bald Eagle

Adult Golden Eagle and Bald Eagle

The Golden Eagle (Aquila chrysaetos) and the Bald Eagle (Haliaeetus leucocephalus) are the largest and most emblematic North American raptors. Both eagles are the national bird of Mexico and the United States of America, respectively.

A large raptor with a uniform dark brown plumage quickly identifies an adult golden eagle. Perhaps even easier to recognize is the bright white head and tail, yellow bill, and dark brown body of an adult bald eagle.

But the plumage of both eagle’s juvenile and immature stages is similar and is the primary source of confusion.

Both eagle species take four and a half to five years to acquire adult plumage. The Golden Eagle goes through relatively similar plumages before reaching the adult plumage. In contrast, the Bald Eagle goes through several different plumages before acquiring the familiar adult plumage.

This article lists similarities and differences between juvenile and immature golden and bald eagles. Familiarizing yourself with these young eagles’ appearance should enable you to quickly tell them apart and identify them the next time you see them. 

Juvenile and immature eagles

The term juvenile refers to an eagle (or any bird) in its first plumage. After leaving the nest, an eaglet wears its juvenile plumage for about a year before replacing it for the first of several immature or subadult plumages.

An Immature or subadult eagle is a bird older than a year.

Male and female eagles

Female eagles are larger than males. Other than size difference, there is no discernible difference in plumage between sexes as juvenile, immature, and adult birds.

Head differences between juvenile and immature golden and bald eagles

The head of a juvenile and immature golden eagle is similar to that of a juvenile bald eagle. The golden eagle’s head appearance have minor changes between the juvenile and immature periods. On the other hand, a juvenile bald eagle experiences dramatic changes in plumage, beak, and eye colors by the beginning of the second year.

Juvenile bald eagles wear their juvenile plumage for the months they spend on the nest and about half a year after leaving the nest.

Juvenile Golden Eagle

  • The head is dark brown with a noticeable golden nape. The head color goes through little changes from juvenile through immature plumages.
  • The gape and base of the beak are orange-yellow.
  • The beak is dark and stays dark.
  • It has a bright yellow cere.
  • Eye color remains dark brown.

Juvenile and immature Bald Eagles

  • The head is dark brown for only about six months year after fledging.
  • The gape is yellow but less bright.
  • The beak is dark for about one year. Then it begins to turn progressively.
  • The cere is not discernible from the rest of the culmen or upper mandible.
  • The dark brown eyes of a juvenile begin to change color during the second year.

Feathered versus bare legs

The Golden eagle is one of the three  North American raptors that have feathered legs. The others are Ferruginous Hawk (Buteo regalis) and Rough-legged Hawk (Buteo lagopus). The purpose of having feathered legs is not clear. Some suggest that feathers on the legs protect them from cold temperatures. Others suggest that it is a layer of protection from biting and scratching prey. Bald eagle feed largely on fish and may not need protection on the legs.

Golden Eagle

  • The legs are covered with feathers down to the feet. 

Bald Eagle

  • The legs are bare.

Eagle measurements 

Golden, and bald eagles are similar. In both species, females can be up to 25 percent larger than the males. Overall length, wingspan, and weight differences are so small between both species that these metrics offer little help to separate them by size. 

In the field, particularly when perched, bald eagles may look slightly larger, while golden eagles look longer and slinkier.

Length: is the distance between a bird’s tip of the tail and the tip of the beak.
Wingspan: Is the distance between a bird’s wingtips while spread.

Perched Golden and Bald Eagle 

Perched juvenile and immature golden and bald eagles may look confusing, but a closer look reveals differences in tail, breast, and belly colors.

Golden Eagle 

  • The tail is white in the base with a broad black terminal band.
  • The breast and belly are uniformly dark brown.
  • The back and folded wings are dark brown except for some white mottling in some individuals.
  • The head looks proportionally smaller.

Bald Eagle

  • The tail color is variable. It can be dark with some white mottling or rather pale with brown streaks, but never a well-defined bicolored tail.
  • The breast and belly are brown with a variable amount of uneven white mottling.
  • The back is dark brown, also with a variable amount of white mottling.
  • The head looks proportionally larger.

Soaring golden eagle versus bald Eagle

Golden Eagle

  • The wings’ underside shows well-defined white patches that vary in size on each individual. The wing patches get smaller as the bird approaches the adult age.
  • The breast and belly are uniformly dark brown. The base of the tail, seen from below, is white with a conspicuous black terminal band.
  • The white base of the tail gets darker as the bird reaches the age of maturity.
  • The lower back and upper side of the tail are white, seen when the bird tilts over while soaring.

Bald Eagle

  • The wing’s underside is dark with white mottling in juvenile birds but increases during the immature stages. The amount of white mottling is highly variable among individuals.
  • The breast and belly have as much mottling as the wings’ underside.
  • The tail color pattern is generally similar to the breast and belly.
  • In general, juvenile eagles are the darkest brown. They acquire a variable amount of white mottling as immature and revert to the pure dark brown of the adult.

How to Tell a Juvenile Golden Eagle from a Juvenile Bald Eagle
The Habitat type favored by the Golden Eagle (Adult Bird, left) and Bald Eagle (Adult Bird Right). The adult plumage of adult golden and bald eagle are rather distinctive and do not pose a problem in telling them apart.

Golden Eagle

The Golden Eagle is mostly restricted to open and mountainous areas west of the Mississippi River, though it is rare throughout the East and Southeast of the United States.

Bald Eagle

The Bald Eagle is widespread and mostly associated with bodies of water such as lakes, rivers, dams, or any other type that contains fish.

Golden and bald eagle range

The Golden Eagle is a bird from the western U.S. However, it is thinly widespread and rare throughout North America. 

The Bald Eagle has strongholds in eastern coastal states, the Pacific Northwest, and Alaska. But it is also widespread and associates with bodies of water that contain plenty of fish or other types of food. In some regions, both eagles can be found side by side at carcasses.

Eagle behavior

Despite having similar hooked bills and powerful talons, the bald and golden eagle are not closely related and do very different things to obtain their food. Both eagles can be opportunistic and will eat carrion when it is available.

Golden Eagle

The golden eagle is more closely related to hawks and is more of a pursue hunter of rabbits and other small mammals. Golden eagles are seen alone or in pairs; they do not form large concentrations around sources of food.

Bald Eagle

The Bald Eagle belongs to the group of fish-eating eagles and feeds mostly on fish and, to a lesser extent, on small waterfowl. The bald eagle can be seen alone, in pairs, or large concentrations around sources of food.

Final Remarks

During the early 1970s, seeing a Bald eagle was a rare event. The Bald Eagle was on the brink of extinction due to DDT’s widespread use.  The Golden Eagle was not as affected by DDT’s general use because its prey base feeds on grass and was not affected by DDT.

On what is now a successful conservation story, the Bald Eagle has regained numbers and continues to recover to the point that it is now fairly common in certain areas.

The bald and golden eagle are unlikely to be seen together in their respective habitats, which should be a good starting point in telling juvenile golden and bald eagles apart. Both species are more likely to be seen together at carcasses.

The next time you see a dark brown eagle, begin by picking on tail coloration patterns and extent of white mottling on the body. Other differences are noticeable at close range. Pick one or two field marks to quickly and confidently tell apart a juvenile or immature golden eagle from a juvenile or immature bald eagle. Identifying eagle with confidence will help you make accurate lists and reports of your sightings.
