I want to tell you about these amazing old books I recently acquired. A couple of weeks ago, my mom and I went to our local “indoor flea market.” I happened across this old hardbound green book called Wonders of Animal Life, volume four. It’s one of those great old 1920s or 1930s books with the copperplate photo captions and tinted plates for illustrations and lots and lots of black-and-white photos. I fell so in love with volume four that I had to hunt down the rest of the series, and through AbeBooks.com, I found someone selling volumes 1–3. What luck! They arrived today and they’re just as wonderful as volume 4.

The series comprises essays by various scientists and other kinds of experts. There’s no rhyme or reason to their selection or to their arrangement, as far as I can tell. Topics include “Strange Tails and Their Many Uses,” “Gluttons of the Sea,” “Long Necks and Short Necks,” “The Gamut of Sound in the Insect World,” The Wonderful Wanderings of Animals,” “Nature’s Strange Show of Freaks,” “Is Evolution Still Going On?,” and, most pertinent to today’s Daily Mammal post, “The Mystery of the Puma” by Hamilton Fyfe.

Mr. Fyfe is a gentleman not unlike our beloved Ivan T. Sanderson, the Daily Mammal’s patron saint. A war correspondent and political propagandist, a practicer of what he termed vagabondage, a man about town with an opinion on everything, Mr. Fyfe here expounds on the puma, also known as the catamount, the cougar, the panther, the painter, or the mountain lion. After explaining that the puma’s favorite food is horseflesh, he states that “it will not attack or even in some circumstances defend itself from the human race…due to some unexplained influence which the human race seems to have upon it.” Fyfe continues, “This influence is strong enough to make the puma…run from man, and even sit unresisting and trembling while man deals it a death-blow.” According to Fyfe, “the natives of South America” refer to the puma as el amigo del cristiano, the friend of the Christian, and “it has actually been known to volunteer its services as a protector of man.”

A photograph of a puma accompanying the essay is captioned “ONLY WILD ANIMAL THAT IS FRIENDLY TO MAN” and informs that “when confronted by man it usually seems to behave like a large and friendly cat. A wild puma will purr in the presence of man and even rub itself against his legs. But apart from this it has the pleasing habit of playing for hours by itself in the midst of the desert at hide-and-seek or at chasing butterflies.”

Now, I know that pumas avoid man whenever possible. In my life as a citizen of the western United States, I’ve seen bobcats, coyotes, and bears, but never a mountain lion. Whether this is due to some magical influence man has over the species, I don’t know, but Fyfe is correct that they avoid us. That makes it particularly unlikely that they really volunteer their services as bodyguards or that they like to rub up against people’s legs, purring, and it’s hard to imagine them cowering in acceptance when dealt a death blow. Maybe in South America that’s true, but it’s hard to imagine.

While mountain lion attacks on people have always been quite rare, they have increased rather alarmingly in recent decades. A month ago, a large animal that may or may not have been a mountain lion attacked a five-year-old boy in the Sandia Mountains here in Albuquerque. As we humans move closer and closer to the homes of other animals, as we do things that make it harder for them to feel safe and find food and live their lives, we experience more encounters of all kinds with wild animals. It would be nice if they all rubbed up against our legs and purred and protected us and chased butterflies with us. I bet they think it would be nice if we just left them alone.

These manatee relatives are big, slow-moving, marine vegetarians who swim around, dragging their flippers and munching on sea grass. In Living Mammals of the World, Ivan T. Sanderson tells us,

They are also rather easygoing, sluggish beasts that drift back and forth with the tides to feed; they used to be found in enormous herds and were so trusting in places where they had not previously been hunted that it is recorded in the accounts of early voyages that they could be patted on the head from small boats…They have been mercilessly persecuted, being harpooned or caught in mile-long nets and then drowned, for they are air-breathers and have to surface to fill their lungs at rather short intervals.

Dugongs live in the Indian Ocean, the Red Sea, and the Pacific, in warm waters from Australia to Africa. They are now rated either endangered or threatened, depending on who’s doing the rating. This friendly dugong is for my cousin Hilary. (It was her birthday an hour ago.)

The pronghorn is often called an antelope, but it’s not really an antelope. Another nickname for it is speed goat, but it’s not a goat, either. In fact, it’s in a class—or rather, family—of its own as the only member of the Antilocapridae.

There are antlers, like deer have, and there are horns, like cows and antelope have. Do you know the difference? Antlers are made of bone and are shed each year. Horns are made of compressed hair growing on a bony core and are permanent. Then there are what pronghorns have. Their horns are keratinous, like bovine horns, but they’re branched, like deer antlers, and pronghorns shed them each year like deer do. In fact, no bovines are known to shed their whole horns the way pronghorns do. This seems to me to be the main factor that’s keeping the pronghorn in its own separate family instead of among the bovines.

Before Europeans came to America, there were tens of millions of pronghorn here. Around the turn of the century, they were nearly killed off; now there are about a million left, it seems. The fastest land animal in the western hemisphere, pronghorn apparently evolved solely in North America, never migrating anywhere else. Ivan T. Sanderson has this to say:

Nothing at all like these animals is known anywhere; they are a solitary leftover from pre-glacial times, when their tribe was much more varied…In a matter of speaking, they are a sort of minor experiment in ‘antelopes,’ initiated by Nature and then dropped.

I take issue with the “minor” part. Seeing pronghorn on the flatlands of West Texas and southeastern New Mexico was one of the things I most looked forward to as a child when we’d drive from our house in Midland, TX, to see my grandparents in Tatum, NM. I have a vivid memory of seeing them jump over a barbed-wire fence, but everyone—including my dad and Ivan T.—says they can’t jump fences. It must have been a daydream.

This pronghorn, along with the rest of the New Mexico mammals this week, is dedicated to the memory of Maleta Scrivner, a dear family friend who loved dogs and desert animals.

Those of you who have been following the Daily Mammal from the start know how daunting the rodents are. Nearly half of the 5,000 named mammal species are rodents, and as Ivan T. Sanderson says in Living Mammals of the World, “whole slews of these look almost exactly alike.” Not only are there are thousands and thousands of them, something I had not considered when I decided to begin this project, but there aren’t very good photos of a great many of them. A while back, I drew a set of five sleeping dormice, and found it heartening to check several rodents off the list at once. Here’s another of those multi-mouse drawings. This time we’re tackling five deer mice (major hantavirus carriers), of the Peromyscus genus.

I didn’t have photographs of a single one of these mice. Instead, I had photographs of Peromyscus species that are much more common in the US, and I had very detailed descriptions of these five species from the species accounts in Mammalian Species, which I download in PDF from Virginia Hayssen’s website. Now, let me tell you, I do not as yet speak the language of zoology, but I’m going to learn it. There are standard names for describing animals’ fur, or pelage, as we mammalogists call it: ochre, buffy, tawny, and a wash of brown may all mean tan to you and me, but not to those whose eyes are trained to discern the nuances. Would my biologist readers let me know where I can get a chart or something that shows what those colors really are? I read that Munsell Soil Color Charts are used for describing pelage—is that where these names come from? I’d like to know.

Anyway, in drawing these mice, I had only the scientific descriptions to go on, and only my experience with acrylic paints to help me decipher the meaning of the colors. (Well, that and the fact that I’ve known three cocker spaniels named Buffy.) Here’s where you come in.

CONTEST: I’m going to type, below, some hints from the descriptions of these mice. The first person to identify in a comment to this post which of the five is which wins this drawing, matted and ready for framing. Ted is not eligible. Here we go.

Aztec mouse (P. aztecus):

  • Dorsal coloration is pale ochre mixed with black
  • Sides are reddish
  • Underparts are light buff
  • A black orbital ring is present
  • Size is medium

California mouse (P. californicus):

  • Annulations are not thoroughly concealed
  • Color is generally blackish brown above, sides ochraceous-tawny, venter pale olive gray to buffy brown
  • Largest species of the genus in the United States

Canyon mouse (P. crinitus)

  • Feet white
  • Dorsal pelage silky
  • Dorsal individual hairs lead-gray at base, succeeded by ochraceous to buffy subterminal band, and tipped with brown or back; dark grayish bases of hairs sometimes visible through buffy to pale grayish shade of dorsum
  • Hairs of forehead, nose, and face appearing slightly more grayish than body
  • Venter white
  • Size small to medium for genus

Gleaning mouse (P. spicilegus)

  • Unworn pelage has upperparts rich, tawny approaching ocherous rufous, dusky and dusky-tipped hairs uniformly distributed throughout upperparts
  • Black or nearly black orbital ring extends posteriorly into a grizzled area between the eye and the base of the ear
  • White feet
  • Tail blackish-brown above, white below with coarse annulations
  • Medium in size for the genus

Hooper’s deer mouse (P. hooperi)

  • Upper parts grayish with faint to moderate wash of brown
  • Underparts pale cream
  • Hind feet and lower legs whitish
  • Medium size for genus

Good luck!

Ivan T. Sanderson calls this guy “one of the most astonishing and paradoxical animals known” in Living Mammals. I had never heard of them until Claire e-mailed me to request one, and I’m so glad she did. They’re related to sloths and to civets, and like sloths, they seem to grow algae on their fur that can give them a greenish hue. They’re nocturnal, eat bamboo, other shoots, fruit, tree frogs, and insects, and they live in Asia. Excitingly, Walker’s Mammals of the World says that binturongs make good pets—they’re very affectionate and follow their owners around like dogs! They are also known as bearcats and they have prehensile tails. Please, let’s get one! Or maybe not:

When I first planned a Striped Mammal Week, I had the idea to pick mammals whose names contained seven different synonyms of the word “striped.” I had a variegated something, a streaked something, a lined something, and this fellow, the nine-banded armadillo. That idea didn’t pan out (and really, who would have noticed?), but our armadillo friend is here nevertheless.

Once my husband Ted and I were playing 20 Questions. I was guessing, and after a demanding and confusing half hour or so, I had determined that I was looking for a reptile commonly associated with Texas that was about the size of a breadbox and neither a rattlesnake or a horny toad. Well, I started to get a creeping suspicion. “No,” I thought, “it can’t be.” But I asked him: “You do know armadillos are mammals, right?” Poor sheepish Ted!

I’ve told that story to maybe three people, and two of them said “Armadillos are mammals??” so maybe Ted shouldn’t feel too bad. Despite their plates of armor (the Spanish word for which gives them their common name), armadillos are indeed mammals. Nocturnal mammals, to be exact, that eat insects and live in South and Central America and in south-central America. Their armor, according to Ivan T. Sanderson in How to Know the American Mammals, is made of “numbers of tiny, checker-like bones formed in the skin and fused solidly together”! I wish, actually, that I could just type out his whole description of the armadillo, because it’s so good. But I’ll just leave you with the fact that this mammal’s Latin name means “nine-girdled hairy-footed one.”

Native to Europe, North Africa, and Asia, the European wild boar came to North Carolina in 1912 when a man working in the Snowbird Mountains had 14 of them shipped over to start a game preserve. By the early 1920s, those 14 had grown into 60–100, and a hunt was held with dogs. Well, the hunters managed to kill only two of them, and many of the rest escaped. They multiplied and thrived, and I suppose that most of the wild boars now common throughout North Carolina are descendants of those first 14. (This is all according to the North Carolina Wildlife Resources Commission’s wild boar section.)

About the European wild boar, our old friend Ivan T. Sanderson has this to say:

They are most competent and single-minded beasts and are intolerant of any interference. Even the babies will put up a determined defense and the males will attack with calculated strategy. Their bite is worse than that of any mammal with the exception of the Killer Whale, and actually much worse than that of the Great Cats though being a ripping rather than a slicing action.

Be careful, North Carolina!
