The ruby-throated hummingbirds, which we saw at the English Country Garden, were likely preparing for it migration. In fact, we did not see the red throats. That is not unusual. The red is only visible when the light is just right. Added to that, only the males have the gorgeous red throats and I have heard that males start migration before the females. They might be out of the province all ready. They don’t require health insurance. When conditions are right, they take off. Can anyone blame them?
Some of the ruby-throated hummingbirds migrate over the Gulf of Mexico enroute to South America. As result, they will load up seriously on nutrients before their long flight. During this process, that takes about 2 weeks, the hummingbird will double its body weight. Across the Gulf of Mexico on the way to South America they are not able to stop. Stopping means death.
There basically are very few islands in the Gulf. As a result, they usually embark on a 500-mile non-stop flight that takes about 20 hours and during this time the bird loses 70% of its body weight in less than a day!
The hummers I saw at Assiniboine Park were no doubt getting ready to migrate down south. Their migrations are so astonishing that many continue to think that they hitch rides on the bodies of geese. Personally, I think that is a conspiracy theory. Others claim they ride on cruise ships.
After all, how could such a tiny bird fly non-stop across the Gulf of Mexico? Yet they do it; somehow, as the shoe company says, they “just do it”. Some of them actually follow the coast, taking a longer but safer route. Across the Gulf if the bird encounters a head wind it can die. Headwinds can be deadly. No one said the life of a hummingbird is easy? They also don’t fly in formation to make it easier, as geese do. They migrate alone. That is one lonely and tough flight. It makes even an Air Canada flights look good.

For many reasons, humans are enamored of hummingbirds. Who could blame us? As Charles Bowden who frequently wrote for Arizona Highways magazine, explained,
We are all seduced by hummingbirds, by the flash of color, the sudden iridescence, the rapid movement, the hovering, and the fact that something so small will fly right up to our face. In a world where so much of the wild flees at our approach, hummingbirds seem to promise redemption, whatever the real reason for their behavior.
According to Susan Wethington, “Hummingbirds are one of the few animals people connect with immediately, and every culture with hummingbirds has a positive connection. I think hummingbirds provide an opportunity to engage people in nature and open eyes to the natural world. And quite frankly, if we can’t save hummingbirds, what group of animals can we save?” ]
Bowden was right when he said, “If you want to see the only future worth being part of, you join the world of hummingbirds.” [3] It really does make sense to “protect the joy.” Personally, I don’t want to be a part of a world without hummingbirds. How about you?
Some hummingbirds don’t migrate. The Anna’s hummingbirds live year round in Arizona. Who could blame them for staying? Why do the others leave? Others like the Ruby-throated and Rufous-sided hummingbird migrate amazing distances. Before migrating, hummingbirds have to stock up on a lot of calories. They become “eating machines,” according to Krebbs. They need fat, fat, and more fat to cross the Gulf of Mexico for example, as some ruby-throats traverse that huge bay, it takes about 2 grams of fat for a hummingbird to travel 600 miles. Remember, hummingbirds don’t weigh much more than 2 grams. I gram is equal to 9 calories. They burn from .69 to .74 calories per hour. About 2 grams of fat are needed to cross the Gulf of Mexico. That is why hummingbirds have to nearly double their weight before they embark on this incredible flight. That means hummingbirds consume a piddly 18 calories to cross the Gulf of Mexico.
The ruby-throated hummingbird, which is the most common hummingbird in Manitoba, and the only one I have seen here, is an amazing migrant. It spends its winters in South America and therefore the poor ruby-throated hummingbird has to make an epic journey twice each year. This is the longest migration of any bird in comparison to the size of the bird (except see Rufous). The tiny bird must fly a mighty marathon to cross the Gulf of Mexico in a steady flight of 18 hours across 500 miles of open water. All of this is done without stopping. Stopping would be fatal. So it cannot drink or feed while it crosses the Gulf.
The long and short of it—especially short—is that hummingbirds are amazing creatures.
