Phylogenetic analysis of 31 species representing 12 genera in the family Strigidae (Aves: Strigiformes) including 5 species (Bubo bubo, Otus sunia, O. semitorques, Ninox scutulato, Strix aluco) collected from Korea has been undertaken using nucleotide sequences of the mitochondrial cytochrome b gene. Maximum likelihood analysis was performed and pairwise genetic distances were calculated with Kimura's two-parameter and p-distance. Among well-aligned 959 bp used for this study, 459 sites were variable and 398 sites were informative for the phylogenetic analysis. The family Strigidae was divided into three subgroups, Clade I (Aegolius), Clade II (Athene, Micrathene, Glaucidium and Surnia) and Clade III (Bubo, Nycteo, Pulsatrix, Strix, Otus, Ptilopsis, and Ninox). Also, two separated subgroups in the genus Otus were confirmed by the geographical distribution.

BACKGROUND: Rice paddies not only produce food but also provides wildlife habitats. Although more than half agricultural land of South Korea is rice paddy, a few studies have been conducted in rice paddy ecosystem. We investigated a status of bird using a rice paddy in South Korea using published data. METHODS AND RESULTS: Birds using a rice paddy have been defined as birds which breed, rest or forage on rice paddy, bank, reservoirs or irrigation ditches. According to the publication from 1980s, birds using a rice paddy were total 47 families 279 species. Scolopacidae and Charadriidae (18%), Falconidae, Accipitridae and Strigidae (12%) and Anatidae (11%) used a rice paddy. Half of bird species using a rice paddy visited a dried rice paddy during the winter and 39.4% of them used a flooded rice paddy in spring, autumn or summer. Dependency on a rice paddy was high in ducks, egrets, cranes, and shorebirds. Population of dabbling ducks has decreased for last 12 years while cranes have increased. CONCLUSION(S): Rice paddies provide both migratory and terrestrial birds including endangered species for habitate all through the year in Korea.
