Parasitism is a hostile relationship that helps greatly in the development and evolution of many creatures in their race for survival. Chewing lice of nestlings of the osprey Pandion haliaetus (L.) have been studied in Farasan Island, Saudi Arabia. All previous chewing lice re- cords from this have also been reviewed. Four of chewing lice are previously known to infest P. haliaetus. The nestlings of the osprey in Farasan were only infested by Colpocephalum turbinatum Denny, 1842. This species of chewing lice is recorded herein for the first time from the Kingdom of Saudi Arabia and its distributional pattern is very characteris- tic among three different avian orders (, Columbiformes, and Strigiformes). Colpocephalum turbinatum was found mainly on terrestrial of the Columbiformes and it may be transferred to predatory birds in the other two orders, but the presence of this parasite on some aquatic birds of prey like osprey may indicate that the ancestors of these birds were terrestrial hunters that acquired this from their prey such as doves and pigeons before their transference to aquatic life. The pattern of chewing lice distribution through their host populations and habitats may reveal some important ecological and evo- lutionary events that happened to their hosts in the past. Key words: Colpocephalum turbinatum Denny, 1842, Pandion haliaetus (L.), Saudi Arabia, birds of prey.

Fig. 2. Phylogeny of Acciptridae and some other Falconiformes, including osprey (yellow highlighting), based on mitochondrial Cyt-b, ND2 and nuclear b-fibrinogen intron 7 sequences. From this tree we can recognise osprey as being paraphyletic to the Acciptridae, but it is very close to the family; this led to new classification of birds of prey by extracting this group of raptors from the Falconiformes and erecting a new order Accipitriformes that includes osprey. Colpocephalum turbinatum chewing louse, which is common among Accipitriformes, might have been transfered to the terrestrial ancestors of these groups millions of years ago from their terrestrial prey, namely the ancestors of pigeons (red dot).
