The fifth article in the series on trends in Namibian waterbird populations summarises count data for storks and ibises for the period 1977 to December 2008. For each species the Red Data Book (RDB) status, both global and Namibian, is given, the population trend as per Wetlands International, the number of times the species was counted, the number of times it has passed the 1% population criterion, the maximum count and the sites where it has passed the 1% population criterion.

This article continues the series on trends in Namibian waterbird populations and summarises count data for herons and egrets for the period 1977 to December 2008. For each species the Red Data Book (RDB) status, both global and Namibian, is given, the population trend as per Wetlands International, the number of times the species was counted, the number of times it has passed the 1% population criterion, the maximum count and the sites where it has passed the 1% population criterion.

Namibia was blessed with extraordinary rains in most parts of the country early in 2011 and this is evident in the results of the summer wetland bird counts. Access to many of the count sites was difficult due to the wet conditions. In fact, the count at Lake Oponono had to be abandoned because of the muddy conditions. Rain interrupted many counts and even at Sandwich Harbour the counters had to endure about two hours of pouring rain before continuing with the count. Oddly enough, Tsutsab Vlei, near Tsintsabis in northern Namibia, was bone dry when the counts were done.

This article continues the series on trends in Namibian waterbird populations and summarises count data for herons and egrets for the period 1977 to December 2008. For each species the Red Data Book (RDB) status, both global and Namibian, is given, the population trend as per Wetlands International, the number of times the species was counted, the number of times it has passed the 1% population criterion, the maximum count and the sites where it has passed the 1% population criterion.

This is the last article in a series describing the results of regular wetland bird counts in Namibia. This paper looks at eight coastal sites, including two of Namibia's four Ramsar sites i.e. Sandwich Harbour and Walvis Bay. Unfortunately data for Namibia's other coastal Ramsar site, the Orange River Mouth, is incomplete and hence it has not been included in this analysis. (Larger scale replications of the graphs in this article are attached to the end of this edition).

The third article in the series on trends in Namibian waterbird populations summarises count data for cormorants and darter for the period 1977 to December 2008. For each species the Red Data Book (RDB) status, both global and Namibian, is given, the population trend as per Wetlands International, the number of times the species was counted, the number of times it has passed the 1% population criterion, the maximum count and the sites where it has passed the 1% population criterion.
