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.
