Data on the soil microarthropod fauna, including oribatid mites (Acari: Oribatei), inhabiting the plumage of 114 individuals of 21 species of eagle and falcon and six species of owls from 33 locations in Eurasia and Northern Africa are presented.From between 0 to 71 of individuals of non-parasitic microarthropod were recorded on a single bird.On average there were 4,8±8,6 (±standard deviation) microarthropods, and 2,2±3,0 oribatid mites per bird.The composition of non-parasitic soil microarthropods in the plumage of the studied group of birds was: 44% -oribatid mites (28% of them were adult mites, 14% -nymph and 3% -larvae), 23% -gamasid mites, 18%collembolans, 8% -prostigmata mites, 3% -acaridia mites, 2% -Bdellidae and 1% -small spiders and larvae of beetles.There was no correlation between number of individuals and species of non-parasitic microarthropods in the plumage and the size of bird, although such a tendency had been observed earlier for anceriformes birds.From one to 12 speies of oribatid mites were recorded from different species of raptor.The recorded number of oribatid mite taxa on different species of birds was dependent on the sample size of the studied birds.In total 60 species of oribatid mites from 13 genera were found in the plumage of raptors.About 80% of all recorded species of oribatid mites were found in the plumage in an adult stage, however juvenile stages of 19 species of oribatid mites were also recorded on raptors.Different age stages of four species (Diapterobates humeralis, D. notatus, Platynothrus peltifer and Tectocepheus velatus) were found in the plumage of one bird which can indicates reproduction of these oribatid mite species in bird feathers.The majority of oribatid mite species (86%) recorded in the plumage are widely distributed in Palearctic soils.However, for some species of southern oribatid mite there is a probable northerly dispersal route by birds from a steppe zone to a zone of broad-leaved woods and taiga (Suctobelba ladaria, Peloribates longipilosus) but also southwards from more northern areas of the Far East to the more southern areas of Mongolia (Suctobelbella opistodentata) is possible.Fig.1.Geographic distribution of number of observed raptors.Рис. 1.
