Nest materials were bamboo twigs and pine leaves. There were 5 eggs, pale blue-grey with reddish brown spots, particularly on the obtuse end. Their measurements were mm ( + SD) by mm (± SD) and they weighed g. Fledglings were found in the vicinity of the nest in early July. The breeding habitat and nesting habits of T. celaenops in Nakano- shima are similar to those of the species in the Izu Islands (Higuchi 1973). These breeding records in Nakanoshima suggest the possibility that the species breeds in other islands off Kyushu. Shirai (1956) observed it in late May and early June 1950 on Yakushima, though no individuals have been collected or observed there since the 1960s. Ogawa (1905) and (1958) separated the Yakushima population as a subspecies T. c. yakushimensis, differing from the Izu Island subspecies T. c. celaenops, though its status in Yakushima was not certain at the time. There are no endemic subspecies of birds in the Tokara Islands, but if yakushimensis is a good subspecies, the Nakanoshima population may be equally and possibly similarly distinct in morphology or ecology from the Izu Island population. The song of the Nakanoshima population seemed to be somewhat different from that of the Izu Island population, but no close investigation was Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Britis
