Get to know Why do birds migrate. Some of the most amazing and interesting Bird Migration Facts for kids.
Bird migration facts are very interesting and amazing. School children mostly inquire about them during their science class. It was for this reason that I have listed down some interesting bird migration facts for those who are curious about this unique seasonal trend of birds.
Bird migration is defined as the movement of the birds with the change of season from one area to another area for breeding purposes.
Why do Birds Migrate
You may wonder why birds migrate! Here are some reasons:
The decrease in food supply caused due to the change in season forces the birds to migrate to a place where there is ample supply of food.
The second reason for migration is reproduction i.e. to move into a specific location with warm temperature to raise young in breeding season.
Bird Migration Facts
Daytime Migratory Birds
Night Time Migrators
· Songbirds are known to be night time migrators. They rest and eat during the day at stop places. They fly at night because of still air and low temperature.
How Far is Bird Migration?
· The longest distance of bird migration is covered by the artic tern which is about 18,600 miles ranging from arctic to Antarctic.The bird feed on fish during the long journey from the top to bottom of the earth and vice versa.
· Some species migrate by very low distance in search of food such as seeds, insects and berries.
· Songbirds migrate with several stops on the way called staging areas. Their stay at these areas varies mainly depending upon the weather conditions and fat stored. Some stay for weeks while some may continue their journey after a day rest.
Flight Altitudes during Migration
· Migrating ducks and geese fly with very high altitude with Bar-headed geese having the record of 29,000 feet when it migrates over the Himalayas mountain range.
· Night time migrators usually fly below 2000 feet over land, however, they may rise to a height of 6,500 feet in case of favorable winds.
Bird Migration Facts about Flight Speed
· Shorebirds’ flight speed varies from 30 to 50 miles per hour.
· Songbirds’ flight speed varies from 20 to 30 miles per hours.
Navigation Strategy of the Migrating Birds
· Birds are equipped with amazing sensory organs which help them accurately navigate their path during the migration. Their exceptional vision helps them to identify visual landmarks when migrating at long distance. These landmarks include mountains, coasts and rivers. They can also sense their way through the direction of the sun, stars and earth’s magnetic field.
