Predation/disturbance effects of greater flamingos (Phoenicopterus ruber) on the benthic communities of two Southern African lagoons
Greater Flamingos, Phoenicopterus ruber, were excluded from intertidal areas of two lagoons and subtidal areas of one of these on the Namibian coastline. Macrofaunal and meiofaunal numbers increased at all exclusion sites, but taxon-specific responses were variable. Both intertidal sites were …

Microsatellite-based genetic profiling for the management of wild and captive flamingo populations.
… Caribbean (range 0.12-0.90) and African greater flamingos (range 0.23-0.94) loci. All six microsatellite loci were found to be in Hardy-Weinberg equilibrium and linkage disequilibrium analyses did not suggest linkage for any pair of two greater flamingo subspecies (African and Caribbean) loci. At …

Temporal interactions with flamingo foraging plasticity: ecological effects on basal resources and benthic heterogeneity
… and the broader ecological role of Greater Flamingos as predators in marine sedimentary ecosystems. The specific aim was to test the long-term effects of different foraging structure sizes (which is a subtle form of foraging plasticity) on sedimentary assemblages following foraging …

Flamingo foraging plasticity: ecological drivers and impacts
… by either (1) creating pits, which involves flamingos stirring up deep sediments with their feet or (2) creating channels, in which their inverted bills are swept from side-to-side on the sediment surface. The first objective of the study was to quantify the ecological drivers of decisions …

Isolation and Characterization of Polymorphic Loci from the Caribbean Flamingo (Phoenicopterus ruber ruber): New Tools for Wildlife Management
… populations of Caribbean and African greater flamingos. In addition, four of these loci were used to verify parentage relationships within a captive-breeding population of African greater flamingos. Parentage predictions based upon gamekeeper observations of breeding and nesting did not always …

Flamingo predation impacts on benthic communities: effects of spatial gradients
… abundance were noted at specific sites. Flamingos in this study were not targeting a specific prey group. Thus of the 19 macrofaunal prey items identified, none were significantly impacted across treatments, except for an unidentified polychaete. However, this was once again site …

Environmental determinants of greater flamingo foraging behaviour in an estuarine intertidal sandflat
… foraging distributions of non-breeding Greater Flamingos (Phoenicopterus ruber roseus) within one of their southern African overwintering grounds, the Heuningnes Estuary. This was achieved by comparing spatial level differences in the abundance and size of flamingo foraging pits across sites and …

Flamingo foraging activity as a driver of spatial heterogeneity in Langebaan Lagoon, South Africa
… impacts of different foraging methods used by flamingos on benthic communities. Multivariate and univariate analyses were carried out in order to determine the effects of two different flamingo feeding strategies (pit and channel foraging) on sediment penetrability and macrofaunal community …

Ecological role of mining ponds in Southern Coastal Mines, Namibia
… Grebe, Cape Cormorant, Greater and Lesser Flamingos, Kelp Gull and Common Tern were the most abundant birds. Salinity did not limit bird numbers or diversity, so the northern high-salinity ponds may continue to serve as bird habitat for periods of time much greater than the 15 years after …
