Movements of crab plover #674 during a single low tide on 20 November 2012. The time between points is, in general, 30 seconds during low water and 10 minutes during high water. Lines connect subsequent measured positions. After each measured position, acceleration was measured during 10 seconds. Acceleration-based behaviour classification was done using the variable-time segmentation approach. In the enlargement, the point size of handling is slightly larger for visual reasons. The hourly time budget for this example is shown in Figure  6.
