“…It is consistently a dominant species in all towns where breeding bird communities have been quantified so far (Table 3). The other dove species, the Ring-necked Dove, is often absent in Namibian towns altogether, except for the towns in the north-east (Kopij, 2020;2021c). In South African towns, the Ringnecked Dove is often in the group of dominant species (Kopij, 1996;2000;2001a;2001b;2011;2015).…”

A bird community was quantified in the suburb of Olympia (200 ha) in the city of Windhoek, Namibia. Two years (2014 and 2020) were selected to examine the impact of rainfall and sub- urb development on species diversity and population densities of the selected bird species in this community. The total amount of rainfall in Windhoek in 2014 was much higher than in 2020 (475 mm and 275 mm, respectively). In total, 36 breeding bird species were recorded in the study area in 2014 and 2020: 27 spe- cies in 2014 and 31 species in 2020. The number of species com- mon in 2014 and 2020 was 17. The Sörensen’s Similarity Index was therefore rather low (0.59). In overall, population density of 25 selected bird species was much higher in 2020 than in 2014. Population densities of the Laughing Dove, the Southern Masked Weaver, and Chestnut-vented Warbler in 2014 and 2020 were statistically different, whereas population densities of the Red- headed Finch were similar in both years compared. The breeding bird community in Olympia suburb does not ap- pear to be stable over years, both in regard to species composition and population densities of particular species. This instability may be linked to constant property development of this suburb and around it. Olympia suburb borders on the periphery of the city, which is a savanna slowly transformed into another suburb. Un- der drought conditions, some species from these surroundings may be attracted to the suburbs by water and food. Hence, con- trary to expectation, densities of some species in the suburbs in the year with low rainfall are higher.

“…Comprising more than 20% of all breeding birds in Namibian towns (Kopij, 2016(Kopij, , 2018(Kopij, , 2019(Kopij, , 2020, sparrows comprised only 2.6% in Tsumeb, with the exotic House Sparrow as the only sparrow species recorded. Also, the overall contribution of Streptopelia doves was relatively low (17.0%).…”

Two seasons of the year, dry and wet, are characteristic climate elements in southern Africa. Caused by differential precipitation, this seasonality induces seasonal variation in primary and secondary production. Birds are also affected. An avian community was studied in dry and wet seasons in an urbanised habitat of Tsumeb, a town situated in northern Namibia. Although both the species richness and the general dominance structure were similar in the dry and wet seasons, the avian community differed significantly in terms of population density of more common species in this town. Sörensen similarity index between the dry and wet seasons was low (I = 0.68). As expected, among granivorous species, the Laughing Dove (Streptopelia senegalensis), the Rosy-faced Parrot (Agapornis roseicollis), the House Sparrow (Passer domesticus), and the Southern Masked Weaver (Ploceus velatus) were much more numerous in the dry than in the wet season. However, contrary to expectation, the Blue Waxbill (Uraeginthus angolensis) was much more numerous in the wet than in the dry season. The Red-eyed Bulbul (Pycnonotus nigricans) was more common in the wet season, but other frugivorous species, the Red-faced Mousebird (Urocolius indicus), was more numerous in the dry than in the wet season.
