These hummingbirds weigh less than a nickel, migrate 1,000s of miles

0

The Calliope Hummingbird flies from Central America to the U.S. and Canada every spring — and back again in the fall. Many Ruby-throated Hummingbirds fly a path north across the Gulf of Mexico to the U.S. — that’s non-stop, more than 500 miles over water — and make a return trip in the fall! Imagine a nickel in your hand — the following nine tiny birds weighing no more than that, fly amazing distances every year!

Their journey is fraught with danger. Weather hazards can be fierce: extreme heat or cold; drought can cause dehydration; heavy rains can force them to the ground; strong winds can blow them into obstacles. Predators, especially cats, but also larger birds, rodents, snakes, and even large dragonflies and spiders are known to kill hummingbirds when they can catch them. Windows kill, too, when they reflect trees and hummingbirds crash into them.

So, why do these tiny birds trouble themselves to migrate? Essentially, because they’re tropical birds that began expanding their ranges in the summer and discovered exploitable food resources and nesting spaces in the U.S. and Canada. Unfortunately for them, that doesn’t last. When fall comes, their main food — insects — goes into decline, forcing the birds to move back south. There are, however, some unique hummingbirds that have adapted to North American climates by becoming vegetarians in the winter!

Hummingbirds are noted for drinking nectar, giving the impression that nectar is their primary food, but as Hummingbirds.net puts it “…nectar is just the fuel to power their fly-catching activity…” Still, we can help these valiant little birds as they make their long, long journey by providing nectar, which gives them energy.

So, hang nectar feeders out a little ahead of when you expect the first arrivals. The nectar is simply a sugar solution. It’s easy to make: 4 parts water to 1 part sugar, and don’t use red dye, as it’s unhealthy for them. Shake the solution periodically until all sugar is dissolved. Refrigerate any unused portion. That’s it! Keep the feeder fresh and replace the solution every few days. It’ll last longer in cool weather, but don’t let it become murky, an indicator that it’s getting moldy.

Here are the migrating hummingbirds to watch for, the areas of the U.S. they migrate to and the periods of their expected arrival and departure. Plus, a bit of additional information about them. The time they arrive in your area will depend on your location; for instance, in the cooler northern states, they’ll arrive a bit later in the spring and leave earlier in the fall.

Ruby-throated Hummingbirds are the only breeding hummingbirds in eastern North America. They can only shuffle along a perch, as their legs are too short to walk or hop.

Thousands migrate back and forth across the Gulf of Mexico, 500 miles, non-stop each way.  Arrival: March through May. Departure: late-July to late-October. Weight: 0.1 to 0.2 ounce (2.8 to 5.7 gm).
