The nestling diet of the Fairy Pitta (pitta nympha) was studied by videotaping during breeding period in Jeju Island, 2009. Earthworms of several species were the most common food resources for nestlings, averaging 82% of all items, followed by 4% of Homoptera larvae. The remaining was only rarely recorded, including Lepidopteran larvae and adults, slugs, spiders, beetle adults and larvae (Coleoptera) and grasshoppers. Adults provided the number of preys ranging from 1 to 7 items to chicks per one visit. The average value of prey number per visit was 3.0 (SD = 1.38). The estimated average length of prey was 5.7 cm (SD = 2.85), and 96% of the food items were smaller than 10 cm. The staying time for feeding in an early stage was longer than other stages. Provision rate at a forenoon (mean ± SD, 14.7 ± 4.92) and an afternoon time (15.8 ± 5.30) was not significantly higher than that of noon time (11.7 ± 4.49). These results provide basic information for conservation action of international endangered species of this species. 展开更多
