Median movement distances of dabbling ducks of California’s Central Valley obtained with GPS showing 30 min interval movement distances by hour of the day. Data from the entire duration of the study show longer movements were typically made in the hours around dawn (05:30 to 08:30) and dusk (16:30 to 19:30 h; grey shaded triangles with dashed outline). The grey circles represent distance in meters with the inner circle representing 0 m and the outer 30 m. Grey shading varies according to distance
