Distribution and abundance of Greater Flamingos wintering in the central part of the gulf of Gabès, Tunisia.

Abstract:

The Gulf of Gabès, in south-eastern Tunisia, is one of the most important Mediterranean wintering areas for the Greater Flamingo Phoenicopterus roseus. However, information on the ecological factors shaping the abundance and distribution of this species in this wintering area are lacking. During the winter of 2010-2011, we conducted repeated counts of flamingos in fifteen sites in the central part of the Gulf of Gabès. The collected data were used to investigate the abundance and distribution of flamingos in this particular wintering area. We found that the total number of flamingos inhabiting the studied area ranged from 262 to 1781, and the proportion of occupied sites varied between 27 and 80%. We also found that the abundance and distribution of flamingos showed a peak between mid-November and mid-January. After this period, the flamingos became gradually rare, as a result of adults’ migration to northern breeding areas. In addition, our results showed that flamingos more frequently and more abundantly occurred in large mudflats (bays and estuaries) than in sandy beaches with small intertidal zones. The formers are likely to present more attractive feeding habitats because of their higher prey availability and accessibility. However, human presence (fishermen and shellfishers) did not appear to affect flamingos’ abundance and distribution. Fishermen and shellfishers did not seem to constitute a threat or a major disturbing factor for flamingos.

Ecological analysis and patrimonial value of the breeding birds in the western Babors range in North-East Algeria.

Abstract:

The composition and patrimonial value of the breeding birds across the different available habitats were studied in the Western Babors range (North East Algeria). In this area, 90 point counts were carried out between 4 April and 31 July 2011. Among the 62 species recorded, 19 are of high patrimonial value (including 4 endemic species, the most famous being the Algerian Nuthatch Sitta ledanti). The species with the highest patrimonial value are linked to woodland habitats. Nevertheless, the oldest woodlands (Cedrus atlantica and Quercus afares) harbour the lowest number of species with high patrimonial value. The mean total species richness is higher in open areas than it is in woodlands (except in riparian forests).
