Hummingbirds migrate so they can find a warmer place to live for the winter. They eat flower nectar and bugs, and in the cold, they can't find either of them. THAT'S why they migrate. There is an instinctual clock that tells the hummingbirds when to migrate. People still disagree over the precise mechanism within the bird that causes this.
Just before they answer the call to migrate, they eat in excess and build a layer of rich fatty fuel just under their skin. You can notice the extra fat along the back, belly, and throat. A hummingbird gains 25 - 40% extra body-weight to have enough fuel to travel 1,400 miles - with no wind of any kind. A headwind of only 10 miles per hour will cut that distance down to 600 miles and more than 20 mph will push them backward. However the ruby-throated hummingbird does take advantage of tail winds constantly. Ruby-throats rebuild their reserves in the early morning, travel about 23 miles during the day and forage again in the late afternoon to keep up their body weight.
When you think about migration facts, it is astonishing to learn of the amazing feat that many birds accomplish twice each year as they move between their summer and winter range and back again.
You can track the progress of the Ruby-throated hummingbird as it migrates from its winter grounds in Central America to the nesting grounds in the north on Hummingbirds.net.

It is not easy so is rarely done. Most wildlife rescuers in the UK keep them through the winter and release them the following spring, when the wild ones arrive back, but I doubt anyone knows their survival rate, or if they can migrate successfully in their second year.
The snowy owl migrates south in winter. Barn owls don't tend to migrate at all. If anyone knows anything more, please add it.
