Research Abstract |
The seasonal and spatial variation of avian records in the Tokara Islands was investigated. Nesting pairs or young fledglings were observed in 31 species, including species of conservation concern. Among these breeding species, 10 were not in common with breeders of Yaku-shima to the north nor with those of Amami Oh-shima to the south, suggesting the breeding bird community of Tokara has been formed under the effects of the unique geological history of this area as well as the effects of historical immigrations from nearby source populations and following local extinctions.
