Egypt is characterized by many deserts associated with cities. The desert raven is considered an ancient one of the most abundant birds in the Egyptian desert and is susceptible to a wide range of ectoparasites. therefore, the present study was to identify the ectoparasites that infect brown-necked raven Corvus ruficollis in Wadi Dara, Eastern Desert, Red Sea Governorate, Egypt. During the two years from 2020 to 2022, several parasites were collected from a brown-necked raven. Sixteen live brown-necked ravens and nine nests in the Red Sea governorate were investigated. The collected ectoparasites were thirteen lice species belonging to two suborders, four dipteran species belonging to two families, ten mite species belonging to two families, also nine tick species belonging to two families. Generally, ectoparasites are considered the primary cause of many dangerous effects for many domestic and migratory bird species, the presence of the brown-necked ravens in the bird migration route in the eastern desert increases the chance of ectoparasites transmission between different species in the same area.

Chewing lice, ticks, mites, and other ectoparasites can infect migratory birds and transmit to resident birds. Ectoparasites cause allergic reactions, irritation, anorexia, decrease in economic income, and may transmit some pathogens between birds. Our current study examined and detected ectoparasites on migratory birds in the Eastern Desert and Gabel El Zeit area, Red Sea, Egypt. During this study, we examined eighty-two migratory birds to detect ectoparasites between March 2019 and May 2022. In this period, we collect 82 newly dead migratory birds belonging to 7 orders; 36 birds of Ciconiiformes, 35 birds of Accipitriformes, four birds of Coraciiformes, two birds of Falconiformes, two birds of Pterocliformes, two birds of Suliformes, and one bird of Columbiformes were examined for ectoparasites. The collected ectoparasites from the migratory birds were preserved freezing or in 70% ethanol until identified as species in the laboratory examination. A total of twenty-six ectoparasite species were collected, belonging to 16 lice, four ticks, four flies, and two mites on migratory birds. Concluded that more studies should be conducted aimed at studying ectoparasites on all species of soaring birds migrating through Egypt.
