The Animal Migration Routes Across North America Are As Followed
North American animals will go to tremendous efforts to move from cold to warm conditions. The caribou is particularly remarkable, as it may travel up to 3,025 kilometers in a single year.
This map depicts North America’s major mammalian mass migration routes. Large mammals aren’t the only ones affected. Monarch butterflies can fly up to 3,000 miles to their wintering grounds. While the map does not identify which species travel these pathways, it does provide a wonderful image of how far creatures will go to survive.
