We counted waterbirds along a fixed route in the panhandle of the Okavango River in Mahango Game Reserve in the dry season during two seven-year periods (1991–1997 and 2000–2006). Palearctic migrants represented by 11 species in 1991–1997 and nine species in 2000–2006 together composed only a small percentage of all birds recorded in both periods. The two most numerous foraging guilds were birds foraging in shallow water and those foraging in deep water. The former guild was more numerous in 2000–2006, while the latter guild was more numerous in 1991–1997.

The Okavango River system, about 480 kms of which constitutes the border between Namibia and Angola, has previously been largely neglected in the annual wetland water-bird counts programme conducted throughout Namibia. The exceptions have been the Mahango Game Reserve and a section of the river at Shamvura Camp where voluntary wetland water-bird counts have however been conducted over a consecutive period of 15 years and 11 years respectively. The remainder of the river had been left uncounted until 2012.

Etosha National Park has a long history of aerial game counts, the first experimental counts being conducted in the late 1960's. Only in the late 1980's were systematic sample counts introduced. A big advance in the actual procedure and analysis was made with the introduction of GPS and GIS software used since 1995. The 2000 census is the third census flown based on GPS transects and were GPS waypoints were recorded for sightings made.

Etosha National Park, hereafter referred to as Etosha, was counted as part of the first co-ordinated regional Elesmap census from 15 July to 3 August 1995. The aim of this report is to present the results of the elephant count, data for the other species will be presented separately. Etosha is a 23 000 km² conservation area surrounding a large saline pan. The vegetation is mainly open Mopane and Acacia savanna and short grass plains. Topography is mainly very flat, with only a few hills in the west. For a detailed description see inter alia le Roux et al.(1988).
