The hooded merganser is one of 96 species with 50 percent or more of estimated Western hemisphere breeding population in North America’s boreal forest.

The number of birds breeding in North America’s boreal forest region is estimated at between 1.65 and 3 billion. Of these, landbirds are by far the most numerous, making up 97 percent of all birds breading there. The importance of the boreal forest region as a breeding ground for many bird groups is staggering. Estimates put the total populations that use this region for breeding at 38 percent (26 million) of all waterfowl of Canada and the U.S., 30 percent of all shorebirds (7 million) and 30 percent of all landbirds (1-3 billion).
A total of 276 species have five percent or more of their breeding range within the boreal forest region. Of these, at least 96 species representing 14 percent of the total Canada/U.S. birds have 50 percent or more of their estimated total breeding population in the region. Another 55 species have 25 to 49 percent of their breeding population within the region.
