Use the buttons above to select different criteria for a feather you've found and attempt to identify it.

Select the pattern or patterns that most closely match your feather. Many feathers will match only a single pattern, but others, such as a barred feather with a broad white tip, will be best described by selecting more than one pattern.

Unpatterned

Two-Tone

Mottled

Barred

Spotted

Iridescence

Dark Tip

Pale Tip

Determine the most characteristic or striking color on your feather, and check the appropriate selection from the list. By characteristic color, we mean the color that is most noticeable on the feather.

White

Black

Black / White

Brown

Gray

Blue / Purple

Green

Yellow / Orange

Red / Rufous

Pink

To further narrow down your search, you can specify the size of your feather in one of four categories:

SMALL: total length less than or equal to 8 cm (approximately 3 inches);
MEDIUM: total length 8-16 cm (3 - 6 inches);
LARGE: total length 16-24 cm (6 - 10 inches); or
HUGE: more than 24 cm (10 inches).
If you don't specify a size category, feathers of all sizes will be searched.

SMALL: Shorter than 8cm
MEDIUM: 8cm to 16cm
LARGE: 16cm to 24cm
HUGE: Longer than 24cm

If you know the position of the feather you are trying to identify, you can significantly narrow your search by choosing from the options below. If you're not sure what type of feather you have, select "Search All Feathers". No selection will still search all feathers.

Sometimes, you'll have a good idea what kind of bird your feather came from. For example, a barred feather with a soft, fuzzy texture is probably from an owl. Selecting options from the list below will allow you to restrict your search to particular groups. You can select as many as you wish.

Waterfowl (Anseriformes)
Gamebirds (Galliformes)
Hawks, Eagles, and Falcons (Accipitriformes and Falconiformes)
Owls and Nightjars (Strigiformes and Caprimulgiformes)
Hummingbirds and Swifts (Apodiformes)
Shorebirds (Scolopacidae and Charadriidae)
Gulls and Terns (Laridae)
Seabirds (Procellariiformes, Alcidae, Pelecanidae, Phalacrocoracidae, Sulidae)
Ciconiidae, Gruidae, Rallidae)
Pigeons and Doves (Columbiformes)
Woodpeckers (Piciformes)
Songbirds (Passeriformes, including Tyrannidae)

The Feather Atlas tool functions as a database-driven system designed to assist users in identifying feathers by allowing filtering based on multiple, specific characteristics. The identification process initiates by prompting the user to select criteria such as pattern, color, size, position, and the likely type of bird from which the feather originated.

For pattern identification, the system offers several categories including unpatterned, two-tone, mottled, barred, spotted, iridescence, dark tip, and pale tip, enabling users to select patterns that most closely match their specimen, acknowledging that complex feathers may require selecting multiple patterns for accurate matching. Color selection allows refinement based on the most noticeable hue, offering options such as white, black, black/white, brown, gray, blue/purple, green, yellow/orange, red/rufous, and pink.

Size specification further refines the search by categorizing feather length into four ranges: SMALL (less than or equal to 8 cm), MEDIUM (8 to 16 cm), LARGE (16 to 24 cm), and HUGE (longer than 24 cm); a choice in this dimension is optional, allowing searches across all sizes if no category is selected. Position filtering helps narrow the search geographically on the feather structure by offering options for primary wing feathers, secondary wing feathers, rectrices or tail feathers, or an option to search all feathers.

To anticipate the source species, the tool provides groups representing different avian types, including waterfowl, gamebirds, hawks and eagles, owls and nightjars, hummingbirds and swifts, shorebirds, gulls and terns, various seabirds, pigeons and doves, woodpeckers, and songbirds. Users have the flexibility to select any combination of these bird groups to restrict the database search based on preliminary knowledge about the feather's origin.

The system subsequently searches its comprehensive database based on the accumulated selections. This structured approach allows for a systematic narrowing of potential matches, moving from broad characteristics like color and pattern to specific locational and taxonomic markers, aiming to identify the feather with high precision.
