Carnivores of the World: Second Edition (Princeton Field Guides) by Luke Hunter and lavishly and beautifully illustrated by Priscilla Barrett is in its second edition. I reviewed the first edition here, where I discussed the idea of having a Order-wide “field guide.” To summarize, you don’t really carry a field guide to all the members of a world wide class around in your pocket in case, for instance, you run into a South American Coati or a Sulawesi Palm Civet on your walk back from your favorite bird blind in northern Minnesota. You have a book like this because you are a student of nature, and you find yourself needing to know about on or another carnivore at one time or another. Or, just because, as a student of nature, you might enjoy sitting in a comfortable chair and studying up on all the carnivores (aside from the carnivorous sea dwellers, which are not covered in this book).Continue reading Field Guide To The Carnivores Of The World: Review
The land and marine iguanas of the Galapagos Islands are famous. Well, the marine iguanas are famous, and the land iguanas, representing the ancestral state for that clade of two species, deserve a lot of credit as well. The story of these iguanas is integral with, and parallel to, the story of the Galapagos Islands, and of course, that story is key in our understanding of and pedagogy of evolutionary biology, and Darwin’s history.

Do you remember Cecil the Lion? He was a loin in Zimbabwe, living in a protected park, somewhat habituated to human presence. A Great White Hunter, who was also a dentist in Minnesota, killed him a couple of years ago, and took a lot of heat for it. The real story of what happened is now out in a brand new book by biologist Andrew Loveridge. Continue reading Remember Cecil the Lion?
A Taste for the Beautiful: The Evolution of Attraction is a popular science book written by an actual expert on the field, addressing the ways in which the world of animals is shaped by sexual selection.
One of Darwin’s major contributions to the panoply of theoretical and observational work we call “evolution” was to recognize, describe, and model sexual selection. Continue reading Sexual Selection Up To Date: A Taste for the Beautiful
I think it is cool that some of them have a heart shape lamp. But wait, there’s more… Continue reading What do fireflies eat? You may not want to know.
I heard a story from a reliable source, who in turn heard it from a fairly reliable source. So believe it or not:
One day a resident of a Nairobi, Kenya — a fairly well off person who liked to collect things — called the police to report that his leopard had gotten out.
So, the police called around and got some leopard traps. Not hard in a place like Nairobi.
They put a dozen, maybe two dozen, traps around the area, in town.
That night and the next, they caught a half dozen or so leopards. None of them were the missing animal. All the caught leopards were wild. Continue reading Leopards Eat Feral Dogs, Limiting Rabies

Grizzly Man is Werner Herzog’s film about Timothy Treadwell, mostly using Treadwell’s own footage of his time living among grizzly bears (Ursus arctos horribilis) in Katmai National Park, Alaska. Treadwell spent each of thirteen summers up to 2003 mainly in two areas of the park where a community1 of grizzly bears lived and foraged. During the last three years of this stint, Treadwell went to the field with video cameras and produced quite a bit of footage. In 2003 he and his girlfriend, Amie Huguenard, were killed and mostly eaten by a bear.
A Field Guide to Britain’s Spiders
No, this is not a new Harry Potter story. It is a pair of books on British Wildlife.
I wish I had Britain’s Spiders: A Field Guide (Princeton University Press (WILDGuides)) Lawrence Bee, Geoff Oxford & Helen Smith for the United States.
The Chelicerata include the Arachnids, which in turn includes such as the scorpions, harvestmen, mites, etc. The largest single group of Arachnids is the spiders (Araneae). They all breath air, they all have eight legs, they all have venom injecting fangs (see THIS for more on that). Of all of the orders of organisms, spiders are seventh in terms of total species diversity, with over 45,000 species. (For reference, there are about 5,400 species of mammal and about 10,000 species of bird. Continue reading The Furry and Creepy Creatures of Britain
Everything you thought you knew about Brown Recluse Spiders is wrong. There is now a book,The Brown Recluse Spider, to set you straight. This is my review of that book.
His name was Bob. I was a kid, he was an adult that all the other adults seemed to think was cool. He used to have a job launching nuclear missiles for the Air Force, but then later got a job as a Hippie. He, another person or two, and I were sitting on a rock pile out in the woods, checking out the patch of marijuana planted, mysteriously, on the neighbor’s property. The neighbor was the head of the local John Birch Society. Whoever planted the patch of pot figured it would be better found, if ever found by the cops, on his property than on the property occupied by the hippies.
Somebody moved a rock. Bob said, “Oh, look, a Brown Recluse spider. They are deadly, but they hardly ever bite.”
I watched the Brown Recluse spider very carefully for a while and memorized it. I found many more over that summer, and in subsequent years. I became very good at identifying them.
This is what it looked like: Continue reading The Truth About The Brown Recluse Spider
Please don’t shoot the swans. My new post at 10,000 birds is here.
Curious George is called a “little monkey” in all of the Curious George literature, TV shows, and movies. But Curious George has no tail, and generally, that means you are an ape. But, there is one monkey with no tail, or at least one that is vestigial and not visible: The Barbary Macaque (Macaca sylvanus). For this reason, some have suggested that George is a monkey, specificaly, a Barbary Macaque or perhaps a close previously undiscovered species.
However, one of the main features distinguishing between monkeys and apes is the intermembral index. This is simply the relative proportion of the forelimbs and hind limbs. Apes have short legs and long arms (unless you are a Man in a Yellow Hat variety of ape) while monkeys have more even length limbs. This image compares a young Chimpanzee to stand in for the apes, a Barbary Macaque, and Curious George, with the limb lengths marked off with a red line.
This seems to indicate the George is an Ape.
Also, note that the Man in the Yellow Hat originally kidnapped George in a Jungle that appears to be in Central Africa, to which he returns in later episodes.
There is another possibility, that Curious George is an undiscovered type of primate that is technically a Monkey but with certain Ape features. We are not certain of the genetic heritage of the mysterious ape Sungudogo, so perhaps George is one of those.
Note that these comparisons are being made among Old World Primates. If New World Primates are included in the mix, there may end up being more questions than answers.
