Preserving a bird wing is straightforward with the right materials and enough patience for drying time. The basic process involves removing flesh and fat, applying a desiccant like borax or salt to prevent decomposition, and letting the wing dry fully over two to four weeks depending on size. Before you start, though, there are legal and safety considerations worth understanding.
Legal Restrictions You Need to Know First
In the United States, the Migratory Bird Treaty Act prohibits possessing feathers, wings, or any other parts of protected migratory bird species without a permit from the U.S. Fish and Wildlife Service. This covers the vast majority of native North American birds, from songbirds to raptors to shorebirds. Bald and golden eagles have additional protections under their own federal law, which bans possession of feathers, parts, nests, or eggs without a specific permit from the Secretary of the Interior.
Birds you can legally preserve include legally harvested game birds (ducks, geese, grouse, pheasants, turkeys, doves) during hunting season with proper licenses, as well as non-native species like European starlings, house sparrows, and pigeons. If you’re unsure whether a species is protected, check with your state wildlife agency before keeping any part of it.
Handling a Dead Bird Safely
Wild birds can carry avian influenza, salmonella, and external parasites like feather lice and mites. Wear disposable gloves when handling any dead bird. If you don’t have gloves, turn a plastic bag inside out and use it as a barrier. Work outdoors or in a well-ventilated area, and wash your clothing in hot water afterward. The USDA recommends disinfecting your shoes with a solution of one part bleach to ten parts water, soaking them for at least ten minutes.
Freeze the wing before you begin processing it. Place it in a sealed plastic bag and put it in a chest freezer (ideally at around 0°F or colder) for a minimum of three days. Ten days is better. For a thorough kill of parasites, freeze the wing for a few days, thaw it for several hours, then refreeze it. This freeze-thaw-freeze cycle is what museum specimen preparators use to reliably eliminate lice, mites, and beetle larvae. Don’t just toss a wrapped wing into the freezer and hope for the best: direct contact with cold air speeds the process.
Removing Flesh and Fat
Once the wing is thawed, use a sharp knife or scalpel to carefully separate as much meat and connective tissue from the skin as possible. Focus especially on the thick areas near the shoulder joint and around the base of the flight feathers. Coarse salt massaged between skin and remaining tissue helps release stubborn bits. Fat is the biggest enemy of long-term preservation because bacteria feed on it, causing odor and decay. Make small crosscuts in any fatty areas and work borax into them abrasively to scrub the fat away.
Take your time with this step. Rushing it is the most common reason preserved wings develop an off smell weeks later. Every scrap of fat or muscle left behind is a potential site for bacterial growth.
Washing and Degreasing
If the feathers are dirty or oily, wash the wing in lukewarm water with a few drops of liquid dish soap (Dawn or a similar degreasing formula works well). Gently work the soap through the feathers, then rinse thoroughly in clean water at the same temperature. Temperature consistency matters: sudden shifts from hot to cold can damage feather structure. Pat the wing with a towel and use a hairdryer on low heat to fluff the feathers back into shape as they dry. Don’t skip the rinse. Soap residue left in feathers will make them look dull and clumped.
Three Desiccant Methods
Borax (Simplest and Most Common)
Borax, sold in the laundry aisle of most grocery stores, is the go-to preservative for most hobbyists and fly tiers. After fleshing the wing, coat the exposed skin side liberally with borax, working it into every fold and crevice, especially near the tail end of the wing where tissue is thickest. Pin or tie the wing into the position you want (spread open or folded) on a piece of cardboard, then let it dry in a well-ventilated area for at least a month. Borax both absorbs moisture and creates an alkaline environment hostile to bacteria.
Salt Water Soak
Submerge the wing in a saturated salt solution (dissolve pickling salt or coarse rock salt in water until no more dissolves) and soak it for two weeks. After soaking, remove the wing, pin it into position on a board, and let it air dry for another two weeks. This method penetrates tissue more evenly than dry borax, which makes it a good choice for larger, thicker wings from waterfowl or turkeys.
Cornmeal and Borax Mix
Bury the wing in a container filled with a mix of cornmeal and borax. The cornmeal absorbs moisture while the borax handles preservation. Leave it buried for about a month. This method is hands-off and works well if you want to preserve a wing in a folded, natural position without pinning it.
Drying Times by Bird Size
Small songbird-sized wings (if legally obtained) dry fastest, typically reaching full dryness in two to three weeks with borax. Duck and grouse wings need a full month. Large birds like turkeys or geese can take six weeks or longer, especially in humid climates. The wing is ready when it feels completely rigid and lightweight, with no soft or flexible spots in the skin. If any area still feels pliable, give it more time. A wing that gets sealed in storage before it’s fully dry will mold.
Pinning for Shape
If you want the wing spread open for display, pin it into position on a flat piece of cardboard or foam board before applying your desiccant. Use straight pins or T-pins through the leading edge of the wing and along the trailing feather shafts. For a folded wing (common for fly-tying storage), simply let it dry in its natural tucked position.
For a mounted flying display, you may need internal wire support. Galvanized wire in 10 to 12 gauge works for duck-sized wings in open poses. Smaller folded wings from ducks or similar birds only need 16-gauge wire, while turkey or goose wings in standing or flying mounts may need wire as heavy as 8 gauge. Annealed wire is easier to bend and shape, but galvanized wire provides more rigid long-term support.
Long-Term Storage and Pest Prevention
Dermestid beetles are the biggest threat to preserved wings. These small beetles and their larvae feed on dried skin and can destroy a specimen in weeks. Borax itself offers some protection since borates are toxic to dermestids, but it’s not foolproof over years of storage.
Mothballs (naphthalene) placed in a storage container with your wings are a cheap and effective deterrent. Paradichlorobenzene (PDB) flakes work similarly. Never mix the two, as they react chemically and produce a liquid that can damage specimens. Camphor is another option that works well as a preventive measure, though it evaporates quickly, so you’ll need a near-airtight container to maintain effective concentrations. Keep camphor-treated collections away from living spaces since the fumes are unpleasant in enclosed rooms.
If you want to avoid chemicals entirely, vacuum-seal bags designed for clothing storage work surprisingly well. They create an airtight barrier that physically excludes pests. Store preserved wings in a cool, dry place away from direct sunlight, which fades feather pigments over time. A sealed plastic bin with a few mothballs or camphor tablets, stored in a closet or basement, will keep wings in good condition for years.
If you ever notice tiny holes appearing in the skin or fine powdery dust beneath a wing, that’s a sign of active beetle infestation. Freeze the wing again for at least a week using the freeze-thaw-freeze cycle, then transfer it to a sealed container with a repellent before returning it to storage.
