2005年12月、根室港内の歩道にて、海鳥24個体の死体が見つかった。検査に耐えうる状態であったウミガラス2個体およびケイマフリ1個体を剖検した。その結果、頸部や翼に特徴的な裂傷が認あられたことから、混獲後、同場所に投棄されたものと考えられた。 In December 2005, the carcasses of 24 seabirds were found on a sidewalk near to Nemuro Port, Hokkaido, Japan, and most of them were heavily damaged by other birds and frozen. Among them, two Common Murres, Uria aalge, and one Spectacled Guillemot, Cepphus carbo, were estimated as relatively better condition for postmortem, hence, postmortem examination was performed. Each individual had sufficient subcutaneous fat and was in good nutritional status. In addition, characteristic lacerations were observed in the neck and wings, suggesting circulatory disorders such as congestion of the lungs and venous system. Therefore, it was considered that these seabirds were artificially transported and dumped after being entangled in fishing nets and drowning.
