In October 1981, I surveyed a colony of the Streaked Shearwater Calonectris leucomelas on Toshima Island in the Izu Islands, Japan, in order to collect ectoparasites. The following ectoparasites were collected from 6 Streaked Shearwaters (4 adults, 2 downy chicks): Mallophaga: (1) Longimenopon shiraii, (2) Halipeurus sawadai, and Shiphonaptera: (3) Ceratophyllus hagoromo. These bird lice were found on their hosts' (1) breast and abdomen on downy chicks; (2) axillars, dorsal, and wings of adults and downy chicks; and (3) on an adult and a downy chick in the same nest.
