Night Changes: Why Color Blind People Aren't So Strange (But Really Are at the Same Time)

"Why does your Tyrannosaurus skull have rings on its eyes?"  "Why are reptiles and amphibians, animals often brushed aside as "less superior" to mammals, frequently very colorful?"  "By contrast, why are so many mammals so drab?"  "Does it ever drive you crazy just how fast the night changes?"  All of these questions and more are ones that I've either received or asked over the last few months, and surprisingly, they are all (sort of) tied together.
A selection of the stars of this post.  In the top row from left to right, we have a Prestosuchus skull, Micronesian kingfisher, Opthalmosaurus skull, African elephant, and a white-necked raven.  Second row, we have a male peafowl, Microraptor specimen, myself pulling a "District 9" with a T-rex arm and Stan the T-rex next to me at the Morrison Natural History Museum (now you finally know what I look like [irresistible], you can cross that off your bucket list), a Mandarin Goby, and the hand of Zach Evens descending upon a brightly colored newt.  Finally, in the bottom row, we see a pair of tiger salamanders, a coyote that ran amok on the University of Colorado campus last winter, and several bees swarming a hummingbird feeder at the MNHM.  Did I forget anything?  Oh, right, the album cover of One Direction's new album "Four."  A further bonus for all you "Natural Worlders" out there: can you find the names of twenty-one One Direction songs scattered throughout the blog post?  Try not to stay up all night searching for them, one way or another I have no doubt you can figure it out.  Just shoot me and email, and I can get back for to you about where they are.  Just one of those little things that makes reading my blog so worthwhile.
When people first walk into the Morrison Natural History Museum near Denver, Colorado, you might see a rock hammer-toting, cowboy-hat wearing, beard-wielding paleontologist talking about lizard pseudo-placentas, the anatomy of the dinos in Jurassic park, or whether said dinosaurs would taste like chicken.*  You might notice the bathroom first, which is more or less right across the room from the front entrance.  Or, like most people, you might notice our cast of Stan, one of the most complete specimens of Tyrannosaurus rex known to mankind.  We tend to get a lot of questions about this bad boy (T-rex consistently being the favorite dinosaur of pretty much everybody), and one question that we get a lot pertains to his eyes.  You might have missed it if you were looking at the fantastic picture above, but take a look at the pictures below and you should see it: it looks like we've put little rings where the eyes should be.  The question is: Why does our Tyrannosaurus skull have rings on its eyes?
Believe it or not, this was not a once in a lifetime phenomena, and it is not a trick (excuse me, an illusion) we created to make the placement of the oculars more apparent for the casual observer.  It's real, and it's called the sclerotic ring.  Without getting too technical, the sclerotic ring is a ring of several bones that actually is inside of the eye of the animal, and is usually thought to help support the eye.  What I find really interesting about the ring is that the default condition in vertebrate animals is possession of this bony ring.  Even though you might not see it in a lot of museum specimens due to display difficulties or preservation issues, a sclerotic ring is present in most/all fish, lizards, birds, and dinosaurs.**  You won't see it in modern crocodilians, though, and it seems like at least some snakes don't have them either.  What's another group that doesn't have the ring?  You guessed it: mammals.
One with the ring, one without.  My bro Masaki Kleinkopf poses next to the mounted skeleton of the pterosaur Pteranodon at the Rocky Mountain Dinosaur Resource Center (RMDRC) in Woodland Park, Colorado.  Check out dat ring doe.
A mounted skeleton of the emperor penguin (Aptenodytes forsteri) at the American Museum of Natural History (AMNH) in New York. If you liked it, you should have put a ring on it. 
Skull of the therizinosaur dinosaur Falcarius on display at the Wyoming Dinosaur Center in Wyoming.  One ring to rule them all.
At this point you might be expecting some profound, fascinating statement that explains why some animals have the ring and some animals don't.  Believe me, very few things would please me more than to be able to explain this to you.  Unfortunately, I don't know.  Even more unfortunately, nobody really knows!  Although various explanations have been put forth over the years, I can't really find a fool('s gold fire)proof, satisfactory interpretation that broadly explains this phenomenon, and in this post I don't really wish to wade any further into this debate than we have already.  We have a few more questions to answer tonight.
The small feathered dinosaur Microraptor on display at the Wyoming Dinosaur Center in Wyoming.  You can see both the impressions of feathers off the wings and legs (making this Velociraptor-cousin comparable to the Sopwith Camel British biplane active during World War I), as well as the sclerotic ring nestled within the orbital.  My preciousssss.....
The name of this ichthyosaur, Opthalmosaurus, actually means "eye lizard," the name of which refers to the big @$$ eyes and sclerotic rings of this particular genus.  Better not put it on your finger, Dumbledore, it might be a Horcrux.
The pseudosuchian Prestosuchus, on display at the AMNH in New York.  This ring just exudes fellowship, don't you think?
Why is Nagini usually more brightly colored than Crookshanks or Scabbers?  Why are Polly's pigments predominantly prettier than Pongo's or Perdita's?  Although undeniably more handsome after true love's first kiss, there's no denying than many frogs and toads out there are much more exciting to look at than Prince Charming.  There's got to be a reason why the characters in "Finding Nemo" were so much brighter (sorry Dory, but I mean in terms of color) than Remy from "Ratatouille," or why Kevin is much more conspicuous than Dug in "Up." But what is the reason?  The answer seems to be fairly simple: with few exceptions, most mammals are colorblind. Primates are one of these exceptions, which is why we humans are able to differentiate between cherry and grape Jolly Ranchers and an elephant might fail, and why the Green lantern comic books and Bionicles absolutely tanked in the feline and canine demographics.  Mammals are good at a lot of things, but one thing that they're not very good at is seeing in color.  A picture is better than words in many cases, so check out some pics below of animals that can most definitely see in color.
Here we have a white-necked raven (Corvus albicollis) correctly putting four different colored game pieces into the correct slots at a special Teen Career Day event at the Denver Zoo that I attended with my sister. He did all eight tiles in the correct category, and it didn't take him very long, either! Some of my friends wouldn't be able to do it with such speed and accuracy....
Male peafowl (Pavo cristatus), often referred to as peacocks, are just one of many species of bird that use brightly colored feather to attract their mate.  Maybe that's why Sauron was so angry: he knew that, no matter what he did, the giant eagles would always be able to naturally two-up him.


A Micronesian kingfisher (Todiramphus cinnamominus) sittin' purty at the Denver Zoo.  Return of the King(fisher), am I right?
A clown fish (subfamily: Amphiprioninae) taking refuge amongst the stinging tentacles of a sea anemone at the Denver Zoo. 
The Mandarin goby (Synchiropus splendidus), a particularly beautiful fish, and very brightly colored as well. 
One of my two betta fish (Betta splendens), Juan Priestly.  Bright bodies with frilly fins?  Glad I'm not a betta fish, this one would steal my girl right out from under me.
Just like the default condition for vertebrates is to possess a sclerotic ring, so too does it seem that the default condition for vision is color.  So if mammals are supposedly so superior, why do so many of us lack this colorful condition?  Many paleontologists have been looking back to the Mesozoic Era, the age of the dinosaurs, to try and solve this colorful conundrum.  Just as mammals have been the dominant terrestrial vertebrates for the last 65 million years, so too did the dinosaurs rule the land during the Mesozoic, suppressing all other forms of life and filling most of the major terrestrial niches.  One of those life forms that was consistently suppressed from the Triassic through the Cretaceous was mammals.  Mostly small, shrew-like animals, Mesozoic mammals are usually thought to have been small, nocturnal creatures, pittering and pattering around the bodies of the sleeping dinos, ready to run at a moments notice.  Key word in that last sentence: nocturnal.
Can you see the little mouse-looking animal hiding underneath the box in the middle of the photograph?  That's Hufflepuff (Huffle to his friends), a small meadow vole (Microtus pennsylvanicus) that tried to hide underneath my legs when a red fox (Vulpes vulpes) happily tried to make a meal out of him last year on CU campus!  Knowing he probably had had the vole equivalent of a heart attack and taking pity on him, I said "I'll save you tonight!" and let him recover for a few days in my room before letting him go to let him live while he was young (which isn't long, I don't think most voles live longer than a year or so, but I could be wrong).  A nocturnal critter, he would have very little use for color vision, and has relatively drab coloration.
More wildlife from CU campus!  This coyote (Canis latrans) caused a bit of a stir last winter when it decided to crash on Farrand Field for a few hours, right in the middle of CU campus.  Although not exclusively nocturnal, coyotes are often active at night, but are quite adaptable, as was evidenced by this particular coyote's behavior, alive and well in the middle of campus!  Note the relatively drab coloration.
I have a friend who is partially colorblind, about as colorblind as an elephant according to some recent studies.  If you see him outside, he's going to be wearing sunglasses (unless he's done something to piss off Poseidon).***  Is he doing it just to look cool?  Well, yes, I suppose that's at least partially the case.  But for him, and for many other people who suffer from color blindness, it seems like they make up for it with above average night vision.  Essentially, an imbalance of rods (a photoreceptor that is not sensitive to color but is sensitive to light and dark conditions and aids in night vision) and cones (a photoreceptor that is sensitive to color and less sensitive to light/dark conditions) leads to many who are color blind reporting better than average ability to see what's going on in low-lighting conditions.
An African elephant drinking some water at the Cheyenne Mountain Zoo in Colorado Springs.  Drab colors?  You betcha!
When all of these seemingly disparate ideas are regarded holistically, it seems to make sense.  By default, most vertebrates enjoy a wide range of color vision (sometimes even a wider range than humans!).  However, during the Mesozoic dinosaurian domination, some groups of vertebrates such as the mammals were forced to take up residence during the night.  For millions of years, these little creatures lived a nocturnal existence, and it seems like being able to see in color no longer proved to be a competitive advantage for them.  Following the extinction of the dinosaurs and the subsequent radiation of mammals, it appears that the possession of color vision was unnecessary for them to survive and thrive.  Many mammals are still largely nocturnal today (think of your kitty at home and all of her midnight memories), which might have something to do with this disparity between their rods and cones.  All in all, it would appear that changes of the night can have some pretty profound effects on your ability to see across the color spectrum.


*You will probably come across them doing some serious work as well, but dinosaur taste-testing can be pretty important.
**I thought that Dr. Bakker, who I talked to a lot about this, mentioned that most or all frogs had the sclerotic ring, but I have been unable to confirm or deny this with a quick search through the resources I have at my disposal.

Pictures of my Animals From My New Camera!

For Christmas I got a new camera, a Canon EOS Rebel! I have a ton of awesome pictures that I want to share, including pictures of my pets, some astrophotography, and more!  First, I am going to share some pictures of some of my various critters!  To see some higher quality versions of some of these pictures, check out my Flickr by clicking HERE!  First off, some shots of my beagle-basset dog, Daisy!
My mom with Daisy!
Next up are some pictures of my chubby kitty, Chimney!
Up next are some of my other pets, such as Juan Priestly the betta fish!  I have two, a delta tail and a veil tail, and I can't remember for certain which one is which.
In another tank I have two African dwarf frogs (Hymenochirus boettgeri), and this is the new one I got just a few days ago!  I named after the bright star Aldebaran in the Zodiac constellation of Taurus the Bull!
In the same tank, I also have a snail.  Petco (where the pets go) says that it is a gold Inca snail (Pomacea bridgesii).  However, that scientific name seems connected to a snail that is colloquially called the mystery snail, so I'm not entirely certain what this snail is.  So I suppose the name "mystery snail" truly does seem appropriate!  Anyways, I named him Liam, after Liam Payne in the fantastic band One Direction.  This is what I do to people I like, I name snails after them.  Maybe next time I will upload a picture of my other snail, Zayn Malik.
Second to last, here is a picture of Wolverine, my baby California kingsnake!
Finally, here is a picture of someone who is not my pet, and is actually a pet of some friends of mine, Isabel and Sam Lippincott!  This is their dog Louis, who was actually attacked by a coyote.  He is fine now, and is going to make a full recovery!

Wolf, Jackal, Fox, and the Dingo (to the tune of "Wake Me Up Before You Go Go")

Song number nine in our "Animal Parodies" playlist!  Here, I present "Wolf, Jackal, Fox, and the Dingo," to the tune of "Wake Me Up Before You Go Go" by Wham!  Below is the link to the song:



Here are the lyrics to the song:


Canidae x4

Hesperocyon at the start
Looked like a little fox, quite hard to tell apart
While other lineages begin to wane
The Canidae's numbers just continue to gain
Good hearing and smell, too,
And a strong bite
That's not to mention their great sense of sight
Big old brain up in their head
Some go solo but others live in packs instead

Wolf, jackal, fox, and the dingo
The true foxes don't include the culpeo
Wolf, jackal, fox, and the dingo
On the coast and on the mountains high
Wolf, jackal, fox, and the dingo
Some move in packs while others like it solo
Wolf, jackal, fox, and the dingo
Gray, black, red, golden, and white

You put the gray wolf out of the way
Still got foxes and coyotes in the USA
Down the land bridge they all came
South America would never be the same
They've got the bush dog and the dhole
And Darwin's fox, who's black as charcoal
Then the maned wolf, who despite
It's name eats a lot of fruits and veggies during the night

Wolf, jackal, fox, and the dingo
The true foxes don't include the culpeo
Wolf, jackal, fox, and the dingo
On the coast and on the mountains high
Wolf, jackal, fox, and the dingo
Some move in packs while others like it solo
Wolf, jackal, fox, and the dingo
Gray, black, red, golden, and white
Yeah, yeah, yeah, doggy
Canidae x2

Close in wild dog, prey's in sight
We're eating impala for sure tonight
More pack members means more mouths to be fed
But the benefits of teamwork, not enough can be said

Wolf, jackal, fox, and the dingo
The true foxes don't include the culpeo
Wolf, jackal, fox, and the dingo
On the coast and on the mountains high
Wolf, jackal, fox, and the dingo
Some move in packs while others like it solo
Wolf, jackal, fox, and the dingo
Gray, black, red, golden, and white





Are you diggin' the songs?  Well, then check out our playlist below!

The Sounds of Star Wars

The dog that was once owned by George Lucas has gone down in history in more ways than one.  One very famous example stems from the dogs name: Indiana.  This inspired the first name of the swashbuckling adventure hero "Indiana Jones" from the film franchise of the same name.  Another very important legacy of Indiana (the dog) stems more from appearance.  Apparently, the idea for Chewbacca, the lovable Wookiee from the Star Wars franchise, came to Lucas when he saw Indiana sitting up in the passenger seat of Lucas's own car!  In fact, the name "Chewbacca" apparently is derived from the Russian and Ukrainian word "собака," which means dog.

Ben Burtt, the sound editor for all six Star Wars movies, recorded a number of bear sounds for the purpose of creating Chewbacca's speech.  Along with bears, cats such as the lion and the mountain lion were also recorded.  Camels were used in addition to these fiercer companions.  These were by no means the only contributions by the animal world to the sounds of Star Wars, however!  For example, when it came to the patrons in the Mos Eisley Cantina in Episode IV: A New Hope, many different tactics were utilized.  Synthesized Latin and chopped-up Swahili served for two of the customers, but animals were used as well.  One patron's laughter stemmed from a hippopotamus, while anothers came from a spring peeper tree frog.

That's not all when it comes to the Cantina scene, however!  Ponda Baba was the Aqualish alien, below, who, along with his friend Dr. Evazan, picked a fight with Luke Skywalker and Ben Kenobi.  He was "voiced" by a walrus.  Meanwhile, besides "dogs growling and bats squeaking," the "laughter" of hyenas was also used for the laughter of some of the Cantina's other patrons. 


Here are some more sounds, and what kind of animals contributed to their creation:

Geonosians:  Here is what Matthew Wood, the actor who brought the voice of the famous and much-loved General Grievous to life, has to say regarding the sounds made by the Geonosians:

"I recorded the mating calls of penguins as they came back from the Antarctic to little Phillip Island in Melbourne.  Other sounds came from when I was up in the rain forest; I was in a flying fox area, and they let me get close to these two flying foxes.  One of them had a banana, but the other one wanted some of it, so they started fighting.  They were really mad, and I recorded that whole thing.  So, for the Geonosians, Ben [Burtt] combined mating penguins and fruit bats fighting over a banana."

The penguins that he is referring to are the korora, commonly called the little blue penguins, discussed in a recent post.  They would also not have been returning "from the Antarctic," as these birds, the smallest known penguin, past or present, are not cold-weather birds, and really stick pretty close to Australia.

Boga:  One of my absolute favorite characters (yes, I know, technically she is just an animal, but still) was voiced by a combination of one of my favorite REAL animals, the Tasmanian devil, along with a few yelps from dogs and coyotes.

Wampa scream: An elephant bellow, overlied by the squawk of a sea lion.

Mynocks:  The whinny of a horse played backwards at half the normal speed, beginning with the bark of a seal.

Ugnaughts:  The noises made by these pig-like aliens were primarily from the pups of an arctic fox, as well as the mother, but a bit of "raccoons in a bathtub" was mixed in.

Rancor Noises:  The dachshund owned by the neighbors of Ben Burtt, the Syllas, barking, growling, and hissing.

The Sando Aqua Monster:  The deep growls that this massive creature from Episode I: The Phantom Menace makes were actually from the throat of Burtt's then-three month old daughter, named Emma.  "At one point, she had a growl in her voice when she was crying.  I thought, I can use this!  So I recorded that and then lowered the pitch way down in the computer."

 Kaadu:  The snorts of the kaadu were recorded from the sounds a whale made out of its blowhole when surfacing at San Diego's Marine World.

Kaadu/Gamorrean Guard:  Both of these creatures (the grunts of the kaadu, and everything for the Gamorrean Guard) were recorded from pigs.  Unsurprising, at least for the Gamorrean, given his appearance!

Poggle the Lesser - The leader of the geonosians (that is, until Queen Karina the Great is revealed in season two of the Clone Wars) was voiced in a number of different ways, but partially through "Swahili-type vocal clicks."

Acklay:  This creatures noises and shrieks were created from reworked dolphin noises, as well as a few pig sounds.

Octuparra Droids:  The sounds from these massive droids from the Clone Wars were partially created by cows.

Gor:  Pet of the aforementioned General Grievous, Gor was voiced by a mixture of a lion and a vulture.

Gundark:  This creature, first mentioned in the original trilogy ("You look strong enough to pull the ears off a gundark," said Han Solo to Luke Skywalker after his traumatic ordeal at the hands [haha irony (because the wampa gets his hands cut off)] of the wampa) was created from a conglomerate of a horse and a shrieking parrot.

I have to say, I think one of the coolest places to visit would be Skywalker Sound, the place where all of the sound and stuff for the Star Wars movies and tons of other movies are made, organized, edited, and such.  If they gave tours, then I would totally make the trip out there!  To take a tour of Skywalker Ranch would be absolutely fantastic!

The Light Rail Coyote

There isn't much to this story, but it is quite amusing, as you can probably see in the picture below.

According to Blogger Andrew Smith, "This photo illustrates one danger of building light rail to the far-flung suburbs: unwanted riders."  What happened here?  Pretty much, in the winter of 2002,  a coyote boarded a Red Line Max train at the Portland International Airport in Portland, Oregon.  As it says in the caption in the picture below, the coyote was gypped of its ride, and was force to deboard by the wildlife specialists at the airport.

Brief tangent: why would an airport need a wildlife specialist, let alone specialists, plural?  "For situations like this" you say.  OK, but how often do these situations occur?  I don't really, know, as I am not expert, but still.  Seems a bit shady to me.

Never mind.  I just looked it up.  Here is why: BIRDSTRIKES.

Anyways, the incident also led to the band called "Sleater-Kinney" creating a song called (can you guess it?) "Light Rail Coyote."  An interesting little story, to be sure.

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
A pair of mule deer fawns, near my house
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
A picture of a gray fox, taken by me at Brookgreen Gardens in  South Carolina
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!
