  Results of the eighth winter waterbird census in Libya in January 2012
  Proceedings of the 2nd International Congress “Speciation and Taxonomy”, May 16th-18th 2014, Cefalù-Castelbuono (Italy)

  ABSTRACT
  After sporadic observations and reports on Libyan birds during the last century, a regular census of wintering birds at Libyan coastal wetlands started in January 2005. Results of each winter census till 2011 have been published. The survey of 2012 was carried out by the authors of the present paper. The general aim was to continue the census of wintering waterbirds in Libya, despite the difficulties that faced the team after the War of Liberation, and the fact that certain areas, very important for birds, have been declared military areas. A total of 29,314 individuals belonging to 69 waterbird species was counted. Comparatively, the number of sites covered in 2012 was less than that in previous years of the survey. The majority of individuals counted belong to seven gull species. This survey also observed a total of 56 individuals of Aythya nyroca Guldenstadt, 1770, a Near Threatened species, as well as, for the first time, a single individual of Canada Goose Branta canadensis (Linnaeus, 1758) in eastern Libya.

  ABSTRACT
  Urbanization as a result of human population increase has led to the depletion of natural resources and the destruction of natural wetlands. In contrast, the establishment of treatment and purification of plants has led to the creation of new wetlands (constructed wetlands). Although these new ecosystems established for the treatment of municipal wastewater, and subject to operational and maintenance disturbances, many studies have demonstrated that numbers of bird species using such sites are reasonably higher than expected. The present study has investigated the role of Al-Hadba treatment plant in the conservation of biodiversity and the diversity of birds in particular. This paper emphasizes that, this area is one of the stopover sites for migrating birds, especially aquatic birds, ducks and long-legged waders. A total of 74 species were recorded during the period of study. Moreover, this study observed the breeding of four species; Marbled Teal Marmaronetta angustirostris, Cattle egret Bubulcus ibis, Moorhen Gallinula chloropus, Black-winged stilt Himantopus himantopus. Some factors such as drought, predation and disturbance were affecting the abundance of individuals at the study area.
