Where Does the Canada Lynx Live: Using Common Names to Determine the Native Land of Various Animals

In a PREVIOUS POST, we started looking at different Latin and Greek roots, and how you can sometimes use these to tell a little about an animal, just by looking at its scientific name.  Today, we are going to learn an even more helpful skill: how to tell where some animals live, just by looking at their common name!

This can be a bit of a tough concept, so let's look at a few easier examples to start out.  First off, meet the lynx.  There are three species of lynx alive today, Lynx lynx, L. canadensis, and L. pardinus.  First off, let's look at Lynx lynx, commonly called the Eurasian lynx.  Let's try to figure out where this animal is from by breaking down its name.  Let's first try the "lynx" part of the name.  Can you think of anywhere in the world called "lynx?"  Neither can I, so let's try the first part of the name, "Eurasian."  Can you think of a place called "Eurasian?"  Although maybe not by that exact name, the word "Eurasian" is actually formed from combining the words "Europe" and "Asia," and is a term commonly used in biology, as there is not really a distinct geographic barrier that separates these two continents, as there is between, say, Asia and Australia.  So using this knowledge, where do you think the Eurasian lynx might live?

If you guessed Europe and Asia, then you were exactly right, as you can see in the range map of the Eurasian lynx below!  If you are still having a little trouble with this, go ahead and review the first paragraph before continuing on, and see if you can figure out why you got this question wrong.

Next, let's look at L. canadensis, commonly called the Canada lynx.  We've already established that "lynx" doesn't seem to refer to a place on Earth, so let's look at the "Canada" part of the name.  A quick Internet search comes up with an exotic country by the same name, "Canada."  Let's make a hypothesis about where the Canada lynx makes its home.

If you guessed "Canada," then you are spot on again, as you can see in the range map of the Canada lynx below!  Again, if you are still having some trouble, go ahead and review before you move on again.

Now, the third lynx, L. pardinus, is actually pretty tough.  Called the "Iberian lynx," this Critically Endangered cat is native to only a small bit of the "Iberian Peninsula," in Spain and Portugal.  I knew you guys weren't ready for this one yet, so that's why I skipped it.  Don't worry, you will have another shot at a tough one like this later.

There are actually four members of the genus Lynx, but we've only talked about three so far.  What about the fourth?  And can you tell where all animals live, just by using their common name?  You actually can't always tell, as we can see with Lynx rufus, commonly called the bobcat.  If you break down the name "bobcat" into its component parts, "bo" and "bcat," you can see that neither part of the name refers to a specific place in the world.

I know I'm moving pretty fast, so feel free to hang back for a minute or two if you need a moment for a breather, to recuperate.  Meanwhile, let's take a look at a few more examples.  First off, where do you think the recently discovered Omani owl is from?

As many of you guessed, the country of Oman is exactly right!  Although researchers aren't positive that this is a new owl as scientists haven't been able to closely examine a specimen, initial investigations indicate that this might be a brand new species of owl!

Let's look at the four living members of the penguin genus Spheniscus, Spheniscus mendiculus, S. magellanicus, S. humboldti, and S. demersus.  The first, S. mendiculus, is often called the Galápagos penguin.  Do you think it is named after the Galápagos Islands?  (For those of you who don't know where the Galápagos are, you can consult the map below the picture of the Galápagos penguin.)

Exactly right!  The Galápagos penguins is indeed found in the Galápagos!  The next two, S. magellanicus and S. humboldti, (the Magellanic and Humboldt penguins) aren't actually named for where they live: they are named for famous explorers!

Finally, the African penguin, S. demersus.  You guys have got this by now, I think: where is the African penguin from?

You guys are getting so good at this, I don't think I need to do any more examples!  I do want to point out real fast that you always need to keep in mind whether the common name of these animals references a place on the globe, or something else.  For example the name of the great-horned owl doesn't refer to the fact that it lives in a place called "great-horn."  It merely refers to the fact that the owl appears to have two little horns on its head!
A picture of the great-horned owl that Anne Price and the folks at the Raptor Education Foundation bring to the raptor shows at the Best Western Denver Southwest dinosaur hotel!
And finally, just like the name of the great-horned owl, the name of the red-tailed hawk doesn't mean that the hawk is from "red-tail," it simply refers to the fact that the hawk has a red tail!

You guys sure did great: now go out there and try and make some new friends by telling them all of your new knowledge!

Penguin Party: The Korora and the Magellanic

Today's post is devoted to two of the seventeen (debatably a lower number) of the extant penguin species, the Korora (commonly known as the little blue penguin, the blue penguin, the little penguin, or the fairy penguin), and the Magellanic penguin.  What's the connection with these two penguins?  Well, not really anything, except for the fact that we had just talked about the Korora in a post a few weeks ago, and I had found a few funny videos of both the Korora and the Magellanic! 

The Korora is actually believed to be fairly closely related to the Magellanic penguin, compared to most of the rest of the penguins.  Despite the differences in their genus (the Magellanic belongs to the genus "Spheniscus" and the Korora to the genus "Eudyptula,") most scientists believe that the Eudyptula penguins (only one extant, but likely extinct ones) were the last ones to diverge from the Spheniscus genus. 

As we talked about a few weeks back, the Korora is labeled as "Least Concern" by the IUCN, and inhaibts Australia and New Zealand, as well as a few other random islands in the vicinity.  Interestingly enough, the Korora has also been reported in Chile and South Africa, although the probability of these animals being vagrants (essentially, lost) is quite high.  However, most penguinologists are certain that many populations of penguins started out as vagrants, so who knows!  It is how they would get from one place to another. 

The Penguin Parade (see below) is a major tourist attraction.

HERE is a link to a clip talking a bit about the Penguin Parade.  The clip talks a bit about the work done by the rangers and scientists regarding the Korora, including ranger Ashley Belsar.  For over thirty years, since 1968, this research team has been recording information about the penguins as they come ashore.  An interesting statistic that I learned from this video is that the average penguin spends about 80% of its life in the ocean!

And for those of you who want something a bit more"cutesie," HERE is a video of Cookie, the Korora, being tickled by humans at the Cincinnati Zoo in Ohio!

Native to the South American countries of Chile, Argentina, and occasionally Brazil, the Magellanic penguin is one of four of the Spheniscus genus of penguins, including the African, Humboldt and Galápagos penguins.  Labeled as "Near Threatened" by the IUCN, somewhere in the neighborhood of 40,000 of these penguins are killed each year by oil spills, which has resulted in their decreased IUCN status.

Next, we have two amusing Magellanic penguin videos.  The FIRST is of a Magellanic on a plane, and the SECOND is a trio of Magellanics who accidentally knock over the camera that is filming them.  Enjoy!

Now, we have a few really cute pictures of some of the Magellanic penguins from Sea World: Orlando in Florida!  The second two photos are from a publicity thing where some people from Sea World: Orlando brought some Magellanics to the Star newsroom!  How cute!
