The fifteen species of sea ducks (Tribe Mergini) are the most poorly understood group of waterfowl in North America. The most basic biological information is unknown for some species. Few species have reliable population indices or estimates of annual productivity, and much of our knowledge is based on a very few, localized studies. Also, current survey design is unable to accurately estimate sea duck harvest.
