Hello friendship of mites !
To continue the series of feather mites, here is the nearly famous feather mite of the common pigeon, for those who care about pigeons or doves at least… Its sweety little name is Falculifer rostratus (Buchholz, 1869) , from the family of Falculiferidae.
It feeds on keratin and prefers the flight feathers of wings (better taste or more minerals ?). It makes holes in the plumage and thus can hamper the flight. A favoured place for various species of such feather mites is the junction of barbs with the feather shaft.
According to federmiben.de, this species can be found on the following bird species :
Collared Dove (Streptopelia decaocto)
Crested Pigeon (Ocyphaps lophotes)
Stock Dove (Columba oenas)
African Collared Dove (Streptopelia roseogrisea)
Housepigeon (Columba livia)
Trocaz Pigeon (Columba trocaz)
Woodpigeon (Columba palumbus)
On this same site you will find interesting information about the lifecycle of a feather mite.
Wandering around on the internet, I found the following specialised publications on this species :
- Fine Structure of the Feather Mite Falculifer rostratus (Buchholz 1869) (Acari, Falculiferidae). 150 pages & 88 figures on this species, it is much probably a very interesting publication but unfortunatly far too expensive for me.
- Population density and male polymorphism in the feather mite Falculifer rostratus (Acari: Falculiferidae), H. C. Proctor , G. Williams, D. H. Clayton
I went through this second publication and discovered an interesting phenomenon in the world of mites : the male polymorphism ! It occurs in Mesostigmata (Macrochelidae for example), in Prostigmata but also in Astigmata. The purpose of the study was to determine if the population density has an impact on the ratio of homeomorphic and heteromorphic males, as this can be observed for Sancassania berlesei. Well, the conclusion is not that straightforward because the notion of population density should be observed maybe preferably at the feather level, and not at the whole pigeon level…
In the case of Falculifer rostratus, the heteromorphic male should have leg I, II and the movable digit of chelicera greatly elongated. Is it the case for the shown mite ? I will tell you something… I do not know, I am even not 100% sure I am showing you a male (O my Goodness !), but maybe You know ?
Anyway if you are looking for information to get rid of these parasites for your belowed pigeons, I recommand you to check other sites… this one is dedicated to taxonomy, scientific studies and iconography of parasites (oriented on determination).
Thanks for your interest !
