Why Hummingbirds MigratePosted: April 11, 2012 Posted by: Bradley Caldwell, Inc.
It is believed that the first hummingbird species developed during the ice age. They have always been considered tropical birds, and the majority of them are still today, however, when the layers of ice withdrew from North America the hummingbirds saw an opportunity to discover a new land.
When the tropic region became overcrowded with hummers, making food and shelter supplies slim, these little explorers decide to journey north to take advantage of the abundant preserved of insects and flowering plant life. Because these types of preserves cannot survive in cold temperatures, the hummingbirds needed to travel back to Central America during winter months in order to live. Thus began the famous hummingbird journeys known as hummingbird migration.
