The species harvested are: Ornithyssus bursa, Cnemidocoptes laevis colombae are haematophagous mites; and Falculifer sp which are mites specific to feathers.
Indeed, we have identified seven species of ectoparasites: the mites which are: Ornithonyssus bursa (haematophagous mites), Falculifer sp (feather mites) and Cnemidocoptes laevis colombae (Gale plucking) with four species of lice; Columbicola columbae; Campanulotes bidentatus, Hohorstiella lata (pigeon lice) and Physconelloides eurysema (chicken lice and some columbidae).

A new species of parasitic mite;
Cnemidocoptes jamaicensis, a causative agent of scaly leg in Turdus aurantiacus.
Low power microscopic examination of skin scraping revealed presence of numerous mite and it was identified as Cnemidocoptes gallinae (Fig.
The Cnemidocoptes gallinae mite usually infect juveniles shortly after hatching and latent until later life, however it may spread between adult birds (Paterson, 2006).
The life cycle of Cnemidocoptes gallinae (depluming mite, depluming itch mite) burrows into basal shafts of feathers to cause pruritus (Arends, 2003).
Estudios realizados indican que tanto ectoparasitos como Menacanthus stramineus, Menacanthus cornutus, Menopon gallinae, al igual que Lipeurus lawrensis, tropicalis, Lipeurus caponis, Goniocotes gallinae, Goniodes gigas, Goniodes dissimilis, Cuclotogaster heterographus, Cnemidocoptes mutans, son de frecuente presentacion en este tipo de aves (Ugochukwu & Omije 1986; Trivedi et al.
Los acaros encontrados en este trabajo fueron Ornithoryssus sylvarium (24%), Cnemidocoptes mutans (21%), Epidermoptes bilobatus (8%), y piojos como Menopon gallinae (89%), Goniocotes gallinae (58%), Lipeurus caponis (45%), Menacanthus stramineus (34%), Goniodes dissimilis (21%) (Figura 1).
In some cases the abnormal growth is due to an infection with a mite called
Cnemidocoptes pilae.
En Venezuela existen escasos trabajos sobre esta materia, al respecto Vogelsang [55], comunico el parasitismo ocasionado por Dermanyssus,
Cnemidocoptes y el genero Argas con dos especies descritas.
AWARTS in birds and mammals can be caused by a virus but similar signs to those you describe can also be caused by infestation by the "scaly beak" mite, formally known as
Cnemidocoptes.
