When prey selection is good, populations can be quite dense. At such bountiful times, territories are often quite small with the central activity of breeding pairs sometimes occurring within 300 m (980 ft) of each other. In Botswana, 23 territories were found along 60 km of river and, in Kruger National Park, up to 8 pairs can be found in an 18 km stretch of the Levubu River.[1]
