Impact de la variabilité climatique sur les oiseaux (Pélican blanc, Flamant rose et Dendrocygne veuf) dans le Parc National des Oiseaux du Djoudj

A study on the Djoudj National Bird Sanctuary reveals that climate variability, including rising temperatures and rainfall, has had minimal impact on waterbird populations such as the Greater Flamingo, Great White Pelican, and White-faced Whistling Duck. Despite a slight increase in temperature (0.62°C) and rainfall (6.82 mm) from 1989 to 2020, these birds have shown significant annual population growth, with the White-faced Whistling Duck increasing by 4.6% annually. The research used the Standardized Precipitation Evapotranspiration Index (SPEI), Mann-Kendall test, and TRIM method to analyze climate data. Notably, the Greater Flamingo remains the most vulnerable species to climate change due to its sensitivity to prolonged drought and humidity. The study suggests that these birds' homeothermic abilities and the sanctuary's hydraulic system mitigate the effects of climate variability.
