While the Atlantic Coast of the United States and Canada is a major wintering area for sea ducks, knowledge about their wintering habitat use is relatively limited. Black Scoters have a broad wintering distribution and are the only open water species of sea duck that is abundant along the southeastern coast of the United States. Our study identified variables that affected Black Scoter (Melanitta americana) distribution and abundance in the Atlantic Ocean along the southeastern coast of the United States. We used aerial survey data from 2009 to 2012 provided by the United States Fish and Wildlife Service to identify variables that influenced Black Scoter distribution. We used indicator variable selection to evaluate relationships between Black Scoter habitat use and a variety of broad- and fine-scale oceanographic and weather variables. Average time between waves, ocean floor slope, and the interaction of bathymetry and distance to shore had the strongest association with southeastern Black Scoter distribution.

美国东南海岸黑斯科特栖息地的利用

虽然美国和加拿大的大西洋海岸是海鸭的主要越冬区，但对其越冬栖息地利用的了解相对有限。黑苏格兰鸭的越冬分布范围很广，是美国东南沿海唯一丰富的开放水域海鸭品种。我们的研究确定了影响美国东南海岸大西洋黑狐蝠（ Melanitt americana ）分布和丰度的变量。我们使用美国鱼类和野生动物管理局提供的 2009 年至 2012 年航空调查数据来确定影响黑狐蝠分布的变量。我们使用指标变量选择来评估黑斑鸠栖息地利用与各种大尺度和细尺度海洋学和天气变量之间的关系。波浪之间的平均时间、海底坡度以及测深和距岸距离的相互作用与东南部黑斯科特分布的相关性最强。
