Zoo Spotlight: The Living Desert

So at least a few times now, I have used pictures from a zoo we went to in Palm Desert called "The Living Desert."  An awesome zoo, this place (clearly) focuses a lot more on the desert animals of the world, and introduces you to a number of animals that you immediately recognize, and a number of animals that you might not otherwise be able to see at another zoo.  I thought I could share some of the pictures that I took at this exciting place, and recommend it to one and all as an exciting place to visit if you ever pass by that area!
Sand cat

Let's start off with some of the animals that you might not be able to see at most other zoos.  As regular readers know, I am a pretty big fan of cats, and The Living Desert definitely had its fair share!  For example, the "Near Threatened" sand cat (Felis margarita), the only cat that is found primarily in the desert.  One of my favorite small wild cats, the sand cat is found in the deserts of Africa and the Middle East.

Besides the sand cat, The Living Desert also has a few other small cats, including the Arabian wild cat, one of the many sub species of the wild cat, Felis silvestris.  Unfortunately, this little guy was asleep so I didn't get any pictures, but I did get pictures of two of the other smaller felines: the serval, and the bobcat, each of which we have done an Animal Spotlight on.  The serval is native to Africa, while the bobcat lives all over North America, in both forests and deserts.

Other, larger cats can be found at The Living Desert, as well, including the jaguar and the mountain lion (both of which I got no pictures of), as well as the cheetah.  We saw two or three cheetahs, but they were all doing what cats do best: sleeping!

Another very interesting thing about the zoo is the vegetation.  Many people simply pass over it: but if you do stop to take a look at it, you might notice something interesting: a whole bunch of the plants, both in and out of the exhibits, are very prickly!  This is because the people at The Living Desert have done their best to make the vegetation in their exhibits as accurate as possible.  Pay special attention to the trees once you reach the large exhibit with both giraffes and kudu, a type of African antelope.  These incredibly spiky trees are called acacia trees, and these trees are one of the reasons why the giraffe has such an incredibly long tongue.  I've been able to see this tongue first hand on numerous occasion at the Cheyenne Mountain Zoo, including the last time I went with my friend Masaki Kleinkopf, as you can see in this incredible video.  The giraffe has been forced to evolve its incredibly long, prehensile in order to circumnavigate through and around these spiny branches in order to reach the leaves. 
Look at those spikes on those acacia trees!

Another one of my favorite things at The Living Desert was the Miriam U. Hoover Discovery Center.  Indoor and air-conditioned (which, trust me, was very refreshing after being in a desert for a while!), the Discovery Center had a number of things for younger kids to do, but it was definitely worth stopping in, because they had an exhibit talking about the Pleistocene (2.5 MYA - 12,000 years ago) residents of California!  Here are what some of the coolest fossils were.
Mounted giant ground sloth skeleton

A full skeleton of the eight-foot-tall giant ground sloth.  The relationship between extinct South American ground sloths and the extant tree sloths was one of the most important things that influenced Charles Darwin into his Theory of Evolution, more so than the case of the Galápagos finches that most textbooks cite.  During the Great American Interchange, at a time when many South American species were going extinct due to competition from animals coming down the Isthmus of Panama from North America (like Thylacosmilus), the giant ground sloths were actually able to move the other way, with remains being found even as far north as Alaska.  

The skull of Panthera atrox, the North American lion

A skull of the North American lion (Panthera atrox), as well as a skull from Smilodon, colloquially known as the "saber-toothed cat."

Skulls of Camelops (a type of camel); a dire wolf (Canis dirus), a significantly larger relative of the extant gray wolf; and the Teratorn, one of the members of the family Teratornithidae, a group of birds of prey that lived in North and South America, and includes the largest flying bird known, Argentavis.  Finally, there was a life-sized picture of a mammoth on the wall with a fossil tusk sticking out which was pretty cool as well!

Now, back to the living!  Here are some more pictures of some of the really cool animals that we saw!  
The "Critically Endangered" addax (Addax nasomaculatus), native to the Sahara Desert
The "Endangered" African wild dog (Lycaon pictus), native to (you guessed it) Africa
American badger
Bighorn sheep
Burrowing owl

Another Mexican wolf.  Despite the fact that this wolf looks like it is snarling, it actually wasn't!  I don't actually know what was going on!

There were also tons of lizards running around all over the place!
There was also a really cool, huge, giant train set!  Here are a bunch of pictures of it!

Incredibly detailed: the Monticello vineyards!

So would I recommend The Living Desert to anyone who is going to be in the area?  You bet I would!  Not only is it an excellent zoo, it gives the visitor an interesting and often difficult-to-find view of desert life from around the world!

Antlers Vs. Horns, Part 1: Antlers

Antlers and horns often look the same, but underneath, they are actually quite different!  Today we are going to look at not only what defines both antlers and horns, but also take a look at some of the animals that have each of them!  All aboard!

Let's start off with antlers.  As defined by the Google dictionary thing, an antler is "One of the branched horns on the head of an adult (usually male) deer, which are made of bone and are grown and cast off annually."  Something that I would like to add is that antlers are unique to the family Cervidae, which includes:
  • Deer
  • Elk
  • Moose
  • Caribou (Reindeer)
The only member of the family Cervidae that has horns on both the males and the females is the caribou, frequently referred to as the "reindeer."  However, it has been documented, on numerous occasions, for fertile females from other species of the cervids to occasionally grow antlers, but this is typically due to unusually high testosterone levels. 

The family Cervidae is one of the many families in the order Artiodactyla, frequently referred to as the "Even-Toed Ungulates" (so called because they either stand on two or four toes).  There are around 220 extant (still living, as opposed to extinct) species of artiodactyl, and included within this order are many familiar groups.  These groups, broken down by family, include:
  • Camelidae (Camels and llamas)
  • Suidae (Pigs)
  • Tayassuidae (Peccaries, a close relative of pigs)
  • Hippopotamidae (Hippopotamus)
  • Tragulidae (Chevrotains, a type of small deer)
  • Antilocapridae (Pronghorn)
  • Giraffidae (Giraffe and okapi)
  • Moschidae (Musk deer)
  • Cervidae (Deer)
  • Bovidae (Cattle, sheep, goats, antelope)
(Interestingly, the whales, dolphins, and porpoises should be included within the order Artiodactyla, but instead they have been placed within their own, separate order, Cetacea.  This area of the family tree is still messy, and a possible merging of the two orders, Artiodactyla and Cetacea, is being considered, which would create the order Cetartiodactyla.)

Also included within the order Artiodactyla is the extinct family Entelodontidae.  Later today, we will finally be getting around to what was supposed to be the monthly "What Is It?" challenge, but has turned into more of a quarterly or tri-monthly event!  Anyways, we will be announcing the winners of THE LAST CHALLENGE later this evening, after we look at horns!

Animals of South Dakota: Part 2

NOW.  What animals should you be watching for on your trip?  Well, I am so glad you asked!  There are going to be three main areas where you would be able to see wildlife; the Prairies (P), the Pine Forests (PF), and the Black Hills (BH).

1.  Bison - If you are lucky, you might get stuck for a few minutes as a herd of bison crosses the road in front of you!  Be careful when viewing these animals, and use common sense; don't be the stereotypical stupid tourist and get yourself trampled to death by the bison.  They are the largest living mammals in North America, and can be testy. - P, BH


2.  Mule Deer - Just like we have in Boulder.  - P, PF, BH

3.  Pronghorn - One of my favorite animals, the Pronghorn Antelope is the second fastest animal in the world, and the fastest in North America, capabable of running around 61 MPH.  Why it can do that, we will talk about next Wednesday. - P, BH

4.  Red and Gray Fox, Coyote - Just like we have in Boulder, except for the Gray Fox. - P

5.  Turkey Vulture - Watch for these guys anywhere, but they should be especially easy to spot on the vast swathes of prairie separating you from South Dakota.  They are instantly recognizable by their "V-Shaped" wing profile, their relative lack of wing-flapping, as well as the fact that they are probably circling something in the air.  Usually groups of them will signifiy a dead animal, as they are carrion eaters. - P, PF, BH

6.  Bighorn Sheep - Just like we have in Colorado - PF, BH

7.  These are the main ones to watch for, but if you get really lucky, you might see one of the black-footed ferrets in the Badlands, or a badger in the prairies!
