Spotted Sandpiper
Actitis macularia

Native Range: North America

Notes: a common sandpiper with many distinctive habits: constantly bobbing or teetering as its walks along a shoreline; a flitty motion when it flieslow across water with its wings held mostly horizontal with quick flicks downward; and a tendency toward sex-role-reversal in which a female may have multiple mates and the males assume much of the nesting and other parental duties.
