Abstract
This study investigated the waterbird communities at Siwa Lakes, focusing on the period from November 2021 to May 2023. A diverse array of 26 waterbird species, comprising three resident and 23 migratory species, was recorded across seven orders and twelve families. Charadriiformes dominated, showing significant representation across four families and thirteen species, while Pelecaniformes ranked second. The relative abundance analysis highlighted key species such as the greater flamingo and little egret. Variations in bird species diversity were observed among lakes, with a significant difference between Fatnas and Zamory Lakes compared to Dehaba Lakes. Seasonal patterns of bird abundance consistently highlighted Phoenicopteriformes as the most abundant order, with Charadriiformes peaking during spring. The diversity indices revealed higher numbers and richness in migratory waterbirds compared to residents, emphasizing the ecological significance of migratory populations. This study provided valuable insights into the dynamic waterbird communities, their distribution, and relative abundances, contributing to the broader understanding of ecosystem health and functioning.
