The feather mites, the paper said, coevolved with the eagles, which means they are the ancient ectoparasites, or external parasites, of the first Philippine eagle population.
The feather mites of the Philippine eagles were found to be closely related to the mites found among several eagles of the family Circaetinae or the Serpent-eagle family.
According to the report, most of the bird species host several groups of ectosymbionts, or organisms living together on the surface, including obligatory feather mites and chewing lice species.
Based on the results of the examination, the feather mites are capable of surviving annual antiparasitic treatments for a longtime, citing one of the examined birds named 'Thor,' which was captured in the wild in 1974, and at the day of examination in 2016 hosted a viable population of the mite, H.
For bugs and feather mites, a specialist for each taxon was consulted.
The mites of most Strigiforms species are unknown, but these birds can host a diverse community of pathogenic and feather mites (Philips, 2000).

Of the 80 specimens of Calidris fuscicollis examined, only 26 (32.5%) had feather mites. We found 3 genera belonging to families Avenzoariidae (Oudemans, 1905), Pterolichidae (T rouessart and Megnin, 1884) and Alloptidae (Gaud, 1957) (Table 1).
Feather mites of the subfamily Magimeliinae (Pterolichidae) parasitize sandpipers of the order Charadriiformes, being well adapted to live in conditions of strong airflow (Dabert and Ehrnsberger, 1999).
Feather mites exhibit morphological variations according to their location on the feathers of the host (Roda and Farias, 1999).
Kramerellidae and Pterolichidae in Korea (Acari, Pterolichoidea).
Feather mites were deposited in the mite collection of the Department of Zoology, Sao Paulo State University, Rio Claro, SP.
The prevalence of feather mites was 80.8%, corresponding to 139 infested individuals distributed into 30 species and 15 families of host birds (Table 1).
Hitherto unknown associations between feather mites and birds were recorded for eleven taxa identified to the species level, and nine taxa were recorded for the first time in Brazil (Table 1).
