Distance moved between sequential 30 min locations on dabbling ducks within California’s Central Valley. Distance varied according to the amount of time ducks spent in a track segment (2–48 locations), which also differed between day and night. Segments are segments are sections of the daily (24 h) track that consist of all step lengths that are within 300 m from the starting point of that section of the track. As time (i.e. number of locations) in a segment increased, the distance moved in 30 min decreased. This likely indicates an increasing proportion of time during which the birds are stationary (resting/roosting), with a stronger decline at night than during the day
