Hummingbirds travel thousands of miles each year, from the southern U.S. to northern regions, following warm weather.
They use specific routes, called flyways, often traveling solo and relying on stored body fat.
Migration is triggered by changing daylight and temperature, ensuring they reach food-rich areas.
Hummingbirds remember their routes, returning to the same places year after year.
Along the way, they face challenges like bad weather, limited food, and predators.
Many hummingbirds arrive in the U.S. during spring, marking the start of their breeding season.
They refuel by visiting flowers and feeders, helping with pollination as they journey.
