Although, the wintering grounds of many North American migratory birds also requires attention, now it has become apparent that our attention must be focused north on the Boreal breeding grounds of many of these birds. It is estimated that about 60% of the American bird population found North of the Mexican border nests in the boreal forest ...
A common pattern in North America is clockwise migration, where birds flying North tend to be further West, and flying South tend to shift Eastwards. Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V formation may conserve 12–20% of the energy they would need to fly alone.
Some birds use this flyway to migrate from the Arctic Ocean to Patagonia. [3] Typically birds use this route because no mountains or ridges of hills block the path over its entire extent. [2] Good sources of water, food, and cover exist over its entire length. About 40% of all North American migrating waterfowl and shorebirds use this route. [3]
Waterfowl flyways in the United States. The Atlantic Flyway is in violet. The Atlantic Flyway is a major north-south flyway for migratory birds in North America. The route generally starts in Greenland, then follows the Atlantic coast of Canada, then south down the Atlantic Coast of the United States to the tropical areas of South America and the Caribbean.

While Parker birds for fun in Maine, for work he monitors two migratory bird species, the Eastern whippoorwill and the common nighthawk, one of the longest distance migratory birds in North America.
The blue jay (Cyanocitta cristata) is a passerine bird in the family Corvidae, native to eastern North America. It lives in most of the eastern and central United States; some eastern populations may be migratory. Resident populations are also in Newfoundland, Canada; breeding populations are found across southern Canada.
According to Fort Collins Science Center, which operates the North American Bat Monitoring Program, 40 different kinds of bats present in the United states eat nothing but insects, about 4 to 8 ...
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. [1] Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites.
