Effects of deafening on the calls and warble song of adult budgerigars (Melopsittacus undulatus)

This paper gives a systematic revision of feather mites of the genera Dubininia Vassilev, 1958 and Cacatualges Dabert, Badek and Skoracki, 2007 (Xolalgidae: Ingrassiinae) associated with parrots (Aves: Psittaciformes) of the Old World. Five new species are described: Cacatualges probosciger sp. n. from Probosciger aterrimus (Gmelin) (Cacatuidae) from New Guinea, Dubininia charmosynae sp. n. from Charmosyna pulchella Gray GR (Psittaculidae) from New Guinea, D. micropsittae sp. n. from Micropsitta pusio pusio (Scaltter) (Psittaculidae) from New Guinea, D. nestori sp. n. from Nestor notabilis Gould (Strigopidae) from New Zealand, and D. pezopori sp. n. from Pezoporus wallicus (Kerr) (Psittaculidae) from Tasmania, Australia. Four previously described species of Dubininia are redescribed based on material from type hosts: D. curta (Trouessart, 1885) from Platycercus elegans (Gmelin) (Psittaculidae), D. lorina (Trouessart, 1885) from Lorius domicella (Linnaeus) (Psittaculidae), D. melopsittaci Atyeo and Gaud, 1987 from Melopsittacus undulatus (Shaw) (Psittaculidae), and D. psittacina (Trouessart, 1885) from Strigops harboptilus Gray GR (Strigopidae) from New Zealand. A new diagnosis for the genus Dubininia is provided. A key to all presently known Dubininia species is provided for the first time.

Two morphologically distinct trypanosomes (Trypanosoma ontarioensis n.sp. and Trypanosoma paddae) were found by the haematocrit centrifuge technique in the blood of 53% (64 of 121) of Corvus brachyrhynchos brachyrhynchos wintering in southern Ontario. Trypanosoma ontarioensis n.sp. is a small trypanosome with subterminal kinetoplast. It is monomorphic and not host specific. It was readily cultured in diphasic blood-agar medium. Two-week cultures were infective and contained dividing sphaeromastigotes, epimastigotes, and trypomastigotes. Blood trypomastigotes were detected in low numbers in the blood of inoculated birds (Corvus brachyrhynchos brachyrhynchos, Bonasa umbellus, Gallus domesticus, Melopsittacus undulatus, and Serinus canarius) at 28 and 48 days postinfection. The crows, ruffed grouse, and domestic chicks were laboratory raised while the budgerigars and canaries were from pet stores. One canary that was further examined at 180, 360, 540, 730, and 910 days postinfection still had detectable numbers of trypanosomes in its blood.
