| Abstract | ||
| Ecologically, the presence of avifauna is a crucial indicator of ecosystem equilibrium. The diversity of bird species and their community structure serves as an essential tool for assessing ecological impacts. This study aimed to evaluate the species composition, evenness, and diversity of wild bird species across different habitats in Egypt from May 2023 to February 2024. The study identified 17,387 individuals from 40 resident bird species belonging to 25 families and 10 orders. The house sparrow exhibited the highest relative abundance among resident bird species, followed by the western cattle egret, barn swallow, house crow, rock pigeon, little egret, hooded crow, laughing dove, and common myna. In terms of migratory birds, 6,050 individuals from 39 species across 22 families and 11 orders were observed. The slender-billed gull, little stint, great cormorant, common ringed plover, the European bee-eater, black-winged stilt, and white wagtail had the highest relative abundances among migratory species. The distribution of bird species across different sites revealed that the coastal area (CA) and the Suez Canal & Gulf Suez (SCGS) each harbored 25% of the total number of resident species, followed by the Nile Delta (ND) with 21%, the Nile Valley (NV) with 16%, and the Faiyum (F) area with 13%. For migratory birds, the CA accounted for 48% of all migratory species, followed by the F area at 23%, ND at 13%, SCGS at 11%, and NV at 5%. The highest species richness was recorded in the CA, followed by SCGS, ND, F, and NV. The highest values for the Shannon and Simpson indices were found in the CA, NV, ND, SCGS, and F areas, respectively. It can be concluded that the Egyptian environment, especially aquatic habitats, is a valuable resource for the Egyptian avifauna by providing food sources and nesting sites. | ||
