Drosseluferläufer Actitis macularius

Small shorebird. Constantly bobs its tail while working edges of streams, ponds, and lakes for invertebrates. Several individuals may be found at the same body of water, but never forms tight flocks. Underparts spotted in summer; plain in winter. Listen for two- or three-noted whistled call as they flush from shorelines. Distinctive wingbeats: snappy and below horizontal.
