Bald Eagle Feathers Identification: Bald vs Golden

A bald eagle feather is large and plain: adult wing feathers are uniform dark gray or gray-brown with no pattern inside the vane, and adult tail feathers are pure white. That description comes from *Identification of Bald and Golden Eagle Feathers* (Pepper W. Trail, National Fish and Wildlife Forensics Laboratory, June 2014), the guide US wildlife officers use, and it is the first result for this search.

Check three things, in this order:

• Length. Trail gives almost always 10 inches (26 cm) or more for eagle flight feathers, and at least 8 inches (20 cm) for the shortest secondaries. Anything shorter is not an eagle flight feather.
• Pattern. Plain dark or pure white points to an adult bald eagle. Pale swirls on a chocolate-brown feather point to an adult golden eagle. Brown speckles over white patches point to a young bald eagle.
• Shaft. Eagle shafts are plain and dark on top, with only a narrow V-shaped groove underneath. Fine lines on top or a broad U-shaped groove underneath mean turkey or another gamebird.

Both eagle species reach full adult plumage by about their fifth year (Trail 2014), so a feather from a younger bird can look very different from the adult.

Trail's summary table reduces the species call to four rules:

• Marbling (curved or irregular pale bars, spots and swirls on dark brown) means adult golden eagle. It never appears on bald eagle feathers.
• A large, solid pure-white base with a dark tip means young golden eagle. The white rises from the base as one patch. Yearling golden eagle tail feathers with this pattern are the feathers most prized for headdresses.
• Pure white all over means an adult bald eagle tail feather. Golden eagle feathers are never all white.
• White areas speckled with brown and surrounded by dark means young bald eagle. The white often sits in the middle or even near the tip, and any white at the base is much smaller than on a young golden eagle.

One exception: the outer three to five primaries of a golden eagle are plain grayish-brown with nearly black tips and no marbling. Trail notes these usually cannot be told from a bald eagle's without reference specimens.

Most 'eagle feathers' people find or are offered come from other large birds. Trail's guide lists these checks:

• Canada goose and swans: waterfowl primaries have a shiny, waxy layer (tegmen) on the underside of the vane. Eagles never do. Goose secondaries and tail feathers, and swan tail feathers, are also too short.
• Turkey and other gamebirds: fine parallel lines on top of the shaft and a broad U-shaped groove underneath. Wild turkey wing feathers are strongly barred brown and white.
• Black and turkey vultures: pale shafts that contrast sharply with the dark vane, and paler undersides. Black vultures have white shafts on both sides; turkey vultures usually only underneath.
• Great blue heron: unpatterned but slate blue, paler and less brown than bald eagle, smaller, and without long finger-like tips on the primaries. See our great blue heron feather guide.
• Common raven: truly black, often with a blue gloss. Eagle feathers are dark gray or brown, never truly black. Raven secondaries are 7 to 9 inches (18 to 22 cm).
• Rough-legged hawk: pale tail feathers with dark tips like a young golden eagle, but only 8 to 10 inches (22 to 25 cm) against 12 to 15 inches (30 to 38 cm) for golden eagle.
• Condors: larger. Condor primaries run 17 to 27 inches (43 to 70 cm) against 12 to 21 inches (32 to 54 cm) for eagles.

Trail calls dyed white domestic turkey feathers by far the most common imitation eagle feathers. Before buying or trading a craft item sold as eagle, look for:

• Dye that is too even. The dark part is usually unnaturally uniform, without the shading of a real feather.
• A curved profile. Viewed edge-on, turkey wing feathers arch; eagle feathers do not.
• The shaft lines. Fine lines along the top of the shaft and a broad groove underneath, the same gamebird marks described above.

Some domestic turkey breeds also carry speckles or marbling-like patterns, and their tips can be trimmed to remove the dark band. If a feather passes every test and still looks like eagle, only a specialist with reference specimens can settle it.

Leave it where it is and take photos instead. Under the Bald and Golden Eagle Protection Act of 1940, possessing a bald or golden eagle feather without a permit is prohibited, whether alive or dead, and including feathers, nests and eggs (US Fish and Wildlife Service). The Feather Atlas adds that US law makes no exemption for molted feathers or feathers from road- or window-killed birds.

For a dead eagle or a question about a find, contact the US Fish and Wildlife Service. Its National Eagle Repository in Denver, Colorado (303-287-2110, repository@fws.gov) receives eagle remains salvaged by officials and members of the public and supplies feathers and parts only to enrolled members of federally recognized Native American tribes for religious and cultural use.

Photograph the feather next to a ruler or a coin, from above and below, and a close-up of the shaft. That is enough for any identification tool or expert.

The 1940 act bans taking, possessing, selling, purchasing, bartering, transporting, exporting or importing bald and golden eagles and their parts without a permit (USFWS). A first offense can bring a fine of up to $100,000, or $200,000 for an organization, up to one year in prison, or both; a second violation is a felony. The same agency's regulations allow take for the religious purposes of American Indian tribes under a permit system, which is why the National Eagle Repository exists.

Feathers of most other native birds are covered by the Migratory Bird Treaty Act, which the Feather Atlas says prohibits possessing feathers of native North American birds without a permit, with exceptions for legally hunted game birds and for Native Americans. Our bird feather identification guide covers other species.

The US Fish and Wildlife Service's Feather Atlas is free and includes scans of 438 species. Its Identify My Feather tool filters by:

• Pattern: unpatterned, two-tone, mottled, barred, spotted, iridescent, dark tip or pale tip
• Main color
• Length: small under 8 cm, medium 8 to 16 cm, large 16 to 24 cm, huge over 24 cm. Eagle flight feathers fall in the huge group.
• Position: primary, secondary or tail feather
• Bird group: 11 groups, raptors among them

NatureLens can also suggest a species from a photo, with free scans every day. For eagle feathers, check any suggestion against the length and pattern rules above, because a young bald eagle and a young golden eagle can both show white.
