Abstract：
A yearling, intact, apparently healthy male American black bear (Ursus americanus) died peracutely at a rehabilitation facility in Ontario, Canada while overwintering, after recovery from porcupine quilling a few months previously. The postmortem examination findings support that porcupine quill migration should be a differential for cause of sudden death in wildlife.
摘要：
一岁，完好无损,显然健康的雄性美国黑熊（Ursusamericanus）在安大略省的一家康复机构中急性死亡，加拿大越冬时，几个月前从豪猪精打细算中恢复过来。尸检结果支持豪猪羽毛的迁徙应该是野生动物猝死原因的差异。
