摘要。眼镜海鸠（Cepphus carbo）是一种亚洲东北部特有的海鸟。在日本，它被列为“易危”物种，尽管人们对它的种群状况知之甚少。2011-2014年在日本北部的整个范围内进行了人口调查。1875年至2010年期间，该地区报告了28个已知和6个疑似繁殖群体。在2011-2014年的调查中发现了14个已知和4个可疑的繁殖群落，有1169只个体和294个巢穴。根据我们对两个调查时期的分析，19个殖民地明显消失，目前的12个殖民地的人口减少。我们的模型表明，个体数量少的群体最有可能消失，而其他环境因素（如群体类型、纬度和海温趋势）对当地群体灭绝的影响相对较小。我们的研究表明，在日本，眼镜海鸠的种群状况已经恶化。
Abstract. —The Spectacled Guillemot (Cepphus carbo) is a seabird endemic to northeastern Asia. It is listed as a “Vulnerable” species in Japan, though little is known of its population status. Population surveys were carried out during 2011–2014 throughout their range in northern Japan. Twenty-eight known and six suspected breeding colonies were reported in this region during 1875–2010. Fourteen known and four suspected breeding colonies were found in the 2011–2014 surveys, with 1,169 individuals and 294 nests. Based on our analysis of the two survey periods, 19 colonies have apparently disappeared, and populations have decreased in 12 of the current colonies. Our models indicated that colonies with small numbers of individuals were most likely to disappear, whereas other environmental factors (i.e., colony type, latitude, and SST trends) had relatively minimal effects on local colony extirpation. Our study shows that the population status of the Spectacled Guillemot has deteriorated in Japan.
