This article is one of a series providing information about endemism among birds in the World's various zoogeographic zones. For an overview of this subject see Endemism in birds.
This article covers eastern North America, i.e. the regions of the United States and Canada which lie east of the Rocky Mountains.
There are no families endemic to this region, although a high proportion of the species in the following families are endemics or near-endemics:

Most bird species which are endemic to this region have ranges which are too large to qualify for Birdlife International's restricted-range endemic status; consequently, this region has no Endemic Bird Areas defined. However, there are two secondary areas, namely:

The boreal forest or taiga of the North American continent stretches through a majority of Canada and most of central Alaska, extending spottily into the beginning of the Rocky Mountain range in Northern Montana and into New England and the Adirondack Mountains of New York. This habitat extends as far north as the tree line and discontinues in mixed deciduous-coniferous forests to the south. The "taiga", as it is called there, of Eurasia occupies a similar range on those continents. Throughout the Northern Hemisphere, the boreal forest covers 2.3 million square miles, a larger area than the remaining Brazilian Amazon rain forest. Although it is largely forest, the boreal forests include a network of lakes, river valleys, wetlands, peat lands and semi-open tundra.
