Abstract
Abstract The coastline of Libyan is characterized by different wetlands that are used as roosting areas for many migratory marine birds. They provide shelter, food and nesting ground for many birds’ species during their migration from their home to wintering grounds. Climate change considered as the greatest threat to natural communities in many the world’s ecosystems. It is already affecting birds in different ways. Precipitation and moisture are critically important climate variables to birds. Marine (sea) birds are highly dependent on precipitation to sustain their wetland habitats. Data on wintering birds in Libya were collected through the years 2005 - 2010 and analyzed in order to investigate their relationships with some climatic factors. This study found that precipitation reductions and drought in critical stopover areas have negative implications for marine birds wintering in Libya. However, the decrease and increase in bird numbers were related to the rate of rainfall. Keywords: Coastline, migratory, precipitation and wintering birds.
