Most songbirds will choose to travel at night with the stars serving as their navigational tool. ![]() Hawks and Eagles flying high in the sky might use mountain ridges, while some landbirds might use the coastline. Other birds rely on landmarks to help guide them. However, when the sun is not visible, such as on a cloudy day, birds may stray off and end up traveling in the wrong direction. Some birds will use the sun as a navigational tool during the day. ![]() This means that their paths of migration and how to migrate are already within their DNA. This Arctic Tern (Sterna paradisaea) is a distance migrant that flies through Oregon.īirds use navigational cues, such as landmarks during the day and the stars at night, to help them migrate. In fact, most birds have their migration genetically coded in what’s known as internal maps. The Arctic Tern ( Sterna paradisaea) is the world’schampion long distance migrant with a round trip journey of about 18,641 miles! Long Distance Migrants: birds that move from breeding ranges in the United States and Canada to wintering grounds in Central and South America.Examples include Western Bluebirds ( Sialia mexicana), Long-Eared Owl ( Asio otus), and Killdeer ( Charadrius vociferus). Medium Distance Migrants: birds that cover distances from one to several states.Examples include Cedar Waxwings ( Bombycilla cedrorum) and American Robin ( Turdus migratorius). Short Distance Migrants: birds that migrate only a short distance from lower to higher elevations.Examples include Spotted Towhee ( Pipilo maculatus), Downy Woodpeckers ( Picoides pubescens), Peregrine Falcon ( Faclo peregrinus), and American Kestrel ( Falco sparverius). Permanent Residents: birds that do not migrate and are able to find adequate supplies of food year around.According to the Cornell Lab of Ornithology, there are 4 types of migration: Male Downy Woodpecker (Picoides pubescens) perched on a pole As winter approaches and these resources drop, birds will move back south again. For example, in the spring, birds in the northern hemisphere will migrate northward to refuel on budding plants, abundant insects, and nesting locations. To combat this, birds will move from areas of low or decreasing resources to areas of high or increasing resources, according to the Cornell Lab of Ornithology. As the end of fall draws near, both food and nesting resources become scarce. ![]() In this post, I will cover the exciting topics of why birds migrate, how they migrate, and what unfortunate hazards birds may face when migrating.īirds migrate for two primary reasons: food and nesting locations. Migration is a very essential event, especially for bird species. The term “migration” describes periodic, large scale movements of populations of animals. Many birders and nature enthusiasts love to view bird migration in action: the Cornell Lab of Ornithology provides resources such as migration forecasts and live migration maps so people can observe bird migration in real time throughout the season. Migration is essential for birds, and for birders. Migration season is here at last! Birds you see migrating right now began their migration in late fall, and will migrate back through beginning late winter.
