Data from tick-infested birds passing the Cairo area en route to Europe and Asia lucidly illustrate potentialities for introduction and establishment of isolated tick populations far from the parasite's native range in the Ethiopian Faunal Region. The birds recorded below were trapped in the environs of Cairo on their northward, spring migration. The summer and winter range and migratory habits of each form, briefly abstracted from Meinertzhagen (1930), are included in the present report in order to show the time and geographical area into which their African tick parasites may be introduced. Miscellaneous records from a few other local tick-infested birds are appended for comparative purposes. Methods have been described by Hoogstraal and Kaiser (1957).
