Green winged Teal

North America's smallest dabbling duck. Very common and widespread, The Green-winged Teal remains further north in the winter than other teal. Often rests out of the water, even standing on low snags or branches. Flocks in flight appear very fast because of small size, with rapid twisting and turning in unison. Typically travels in small flocks, but in winter or at migration stopovers, may gather in concentrations of thousands.
