Bowhead whales occur in the Arctic year-round. Their movements are largely correlated with seasonal expansions and reductions of sea ice, but a few recent extralimital sightings have occurred in the eastern and western North Atlantic and one was also documented in the western North Pacific over 50 years ago. Here we present details of a juvenile bowhead whale that was photographed and filmed from above and below the water while it was skim-feeding in Caamaño Sound, BC, Canada on May 31, 2016. This sighting occurred over 2000 km southeast from the nearest known range for this species in the Bering Sea at a time that most bowhead whales in that region would have been migrating northeast. This sighting represents the first and only documentation of a bowhead whale in the eastern North Pacific to date.
北极露脊鲸终年生活在北极地区。它们的活动在很大程度上与海冰的季节性增减相关，但最近在北大西洋东部和西部出现了一些超出其正常分布范围的目击记录，50多年前在北太平洋西部也有过一次记录。在此，我们详细介绍一头幼年北极露脊鲸，2016年5月31日它在加拿大不列颠哥伦比亚省卡马尼奥海峡进行撇食时，被从水面上方和下方拍摄了照片和视频。此次目击发生在距离该物种在白令海已知的最近分布范围东南方向2000多公里处，而此时该区域的大多数北极露脊鲸本应向东北方向迁徙。这是迄今为止在北太平洋东部首次也是唯一一次记录到北极露脊鲸。
