Information About Migratory Birds

Information About Migratory Birds
Understanding the flight patterns and habits of birds might seem difficult at first, and indeed some things might never be understood about certain species. But there are some basic reasons birds migrate.
 

Reasons for Migration

Birds that migrate are those that spend parts of the year in different areas according to what food is available and seasonal weather change. Some species only migrate a short distance in response to abrupt weather changes, but some migrate thousands of miles.

 
 

Routes

Most migratory bird species travel along a "flyway." In the Northern Hemisphere, this is generally south for the winter season and north in spring to breed and raise young.

Formations

Many larger bird species such as geese fly along their migration routes in flocks to help reduce individual stress and save energy by flying in formations that decrease wind resistance, such as the V-formation.

Regions

According to the Forest Service, more than 300 of the 850 bird species in North America spend the summer in the United States, and winter in Mexico and South America.

Irruptive Migrants

Some birds such as the red-breasted nuthatch are considered irruptive migrants, meaning the number that migrate and the winter range varies greatly each year. In this case, the Eastern year-round range is expanding southward.
