Bald Eagle

This feather belongs to the iconic Bald Eagle, a massive raptor known for its white head and tail (in adults) and dark brown body. Juveniles are mottled brown and white. This specific feather, showing both white and dark brown, is characteristic of the transitional plumage seen in sub-adults or the neck-mantle transition in adults.

Bi-colored transition: the base is a snowy white, gradually transitioning through a smoky gray-brown into a solid dark chocolate brown or near-black at the tip. No distinct banding or spots are present.

The distal portion is pennaceous (tightly interlocked), while the proximal base is highly plumulaceous (downy) for insulation. Barbs appear mostly intact with some minor separation at the edges.

The pennaceous portion is smooth and firm with a slight matte finish. The plumulaceous base is extremely soft, airy, and silk-like. The surface lacks the velvet-like pile seen in owls.

The size, solid dark tip lacking bands, and the extensive translucent/white downy base are diagnostic of large Accipitrids, specifically the Bald Eagle.

Found near large bodies of open water (lakes, rivers, coastal marshes) with abundant fish and tall trees for nesting and roosting.

Common across North America, from Alaska and Canada throughout the contiguous United States to northern Mexico.

Apex predator and opportunistic scavenger. They play a vital role in regulating fish and waterfowl populations and serve as an indicator species for environmental toxins like mercury or lead.

Golden Eagle (feathers often have more golden-brown hues and different basal patterns); Turkey Vulture (rachis is typically darker throughout and vanes are less broad).

Bald Eagles build the largest nests of any North American bird, sometimes reaching 10 feet wide and weighing over a ton. They were removed from the Endangered Species List in 2007.

Fair to Good. Shows some mechanical wear at the tip and edges; some barbs are beginning to 'unzip.' Minor dirt or debris is visible in the downy section.
