- W2177941307 abstract "Distribution and reproductive ecology of the White Stork (Ciconia ciconia) in Algeria. The White Stork (Ciconia ciconia) is a breeding bird in the Mediterranean part of Algeria (i. e. from coast to the Hauts-Plateaux). National censuses have been organized as part of project to study the dynamics of bird populations in Algeria. The total number of breeding pairs (HPa) was found to be 6601 in 2007. In the eastern regions (from El-Tarf to Oum-El-Bouaghi), the census resulted in 1855 occupied nests in 1995 and 4411 in 2007 (70 % of the total in both years). In the central regions (from Béjaia to Blida) 701 pairs (26 %) and 1817 pairs (27.5 %) were counted in 1995 and 2007 respectively. In the western regions (from Tipasa to Ain-Temouchent), only 123 pairs (5 %) were found in 1995 and 373 (5.6 %) in 2007. The pairs nesting outside of human settlements often breed in colonies on trees. The selected types of nest supports give a good idea of the changes that have occurred in preference of nest sites. Although, since cities have increased in size and many houses have lost their suitability for storks, some pairs have adopted new buildings to nest, so human-made supports (roofs of houses, electricity poles and pylons) still represent more than half of the total number of nest supports. The population’s increase is particularly striking in the eastern regions of El-Tarf and Mila and in the central regions of Setif where the breeding populations have increased by 263 %, 137 % and 312 % respectively between 1995 and 2007. Notwithstanding that some other factors such as ever-growing urbanization pressure and deterioration of habitat quality still have a negative impact on the White Stork populations we estimate that the above mentioned climatic improvements and the adoption of irrigated farmlands and garbage dumps to feed in certain regions have largely contributed to the recent population increase." @default.
