González-Acuña, Daniel, Moreno, Lucila, Cicchino, Armando, Mironov, Sergey & Kinsella, Mike, 2010, Checklist of the parasites of the black-necked swan, Cygnus melanocoryphus (Aves: Anatidae), with new records from Chile, Zootaxa 2637, pp. 55-68 : 63

Ornithobius bucephalus ( Giebel, 1874)

Site of infection: mostly wing feathers: primaries, secondaries, wing coverts; also in pterylae surrounding this area: scapulars, interscapulars and upper breast.

Localities: Buenos Aires Zoological Garden ( Argentina), London Zoological Garden ( England). References: Castro and Cicchino (1996), Arnold (2005).

Comments: Probably these records are due to secondary infestations from its true host, C. olor because both swan species are frequently confined in the same reduced habitats in Zoological Gardens where they breed freely, as we observed repeatedly in Argentina.
