Description
This feather belongs to an elegant, slender raptor with a distinctive white rump patch. Northern Harriers are unique hawks that hunt by sound as well as sight, utilizing an owl-like facial disk. The warm buff tones of this feather indicate it came from a female or an immature bird.
Colour & Pattern
Base color is a warm cream to ochre-buff. It is marked with fine, dark brown 'peppered' mottling or speckling concentrated on the outer edges and toward the tip, rather than distinct bars.
Barb Structure
Pennaceous (interlocked) in the distal two-thirds with a soft, fuzzy plumulaceous (downy) base for insulation. Barbs are generally intact with minor fraying at the tip.
Texture & Surface
Smooth and soft to the touch with a matte finish. It lacks the oily sheen of waterfowl or the stiffness of primary flight feathers.
Key Features
Warm ochre-buff base color with fine, irregular dark brown speckling (not solid bars) and a significant downy portion at the base.
Habitat
Open wetlands, salt marshes (common in Boothbay), grasslands, and prairies. Known for hunting low over marshes.
Geographic Range
Breeds across North America, including Maine; northern populations are migratory, wintering as far south as Central America.
Ecological Role
High-level predator that controls rodent and small bird populations. They serve as an indicator species for the health of wetland ecosystems.
Similar Species
Cooper's Hawk or Sharp-shinned Hawk (feathers usually have distinct horizontal bars); Red-tailed Hawk (usually has larger, droplet-shaped streaks).
Interesting Facts
Northern Harriers are the only 'harrier' species in North America. They are polygynous, meaning one male may provide food for up to five females in a single season.
Condition Notes
Good condition. There is slight wear and separation of the barbs near the tip, suggesting it may have been molted naturally at the end of a season.
