Redheads, Aythya americana
Local birders consider it a treat to see one or two of these handsome birds among a flock of their similar looking cousins, the Canvasbacks (Aythya valisineria). Today on Fresh Pond near Little Fresh Pond the redheads outnumbered the canvasbacks 10 to 6, a rare sight, indeed. Pictured are three males and one female.
