New Zealand Dotterel: South Island historical notes and Southland coastal records | Notornis and Birds New Zealand

[摘要] Historical records of South Island breeding of NZ Dotterel (Charadrius obscurus) are discussed. The latest discovered South Island breeding record was 1881. No record of South Island coastal breeding was found. Numbers of birds wintering on the Southland coast declined substantially and rapidly from 1972 to 1992. The cause of decline is believed to be a decline in the Stewart Island breeding population. Colour-banded adults had allegiance to a specific wintering ground. Food items of birds at Stewart Island included 10-20 mm juvenile flounders.
