Tufted Duck (center) - Note the size comparison next to Greater Scaup. Also rounded head appearance and whispy, short tuft.
Behaketaren xehetasunak
**Rare. Undecided if this is an imm male or female but relevant field marks seem supportive for pure Tufted Duck. Rounded head, perhaps a bit more peaked toward forecrown (variable depending on posture) but clearly different profile than both scaup species. Noticeably smaller than Greater Scaup and comparable in size, if not a bit smaller in body size than nearby Lesser Scaup. Short tuft slightly hanging over to nape (variable depending on posture-see photos). Yellow eyes and blue bill with extensive black on bill tip separated by a very faint white line. Uniformly dark back-backed appearance making the bird easy to relocate within the flock. Mostly brown flanks with darker brown on breast. The Tufted Duck was not directly associating or favoring any specific scaup species and was often by itself at the edge of the flock. Watched a Greater Scaup snap at it and chase it away. Tried hard to find any clues that might point toward hybridization but described field marks and overall jizz all point toward Tufted Duck.
