The platypus is extraordinary, and this is a book about how we came to know that. Written by a historian of Australian science, Platypus is subtitled, “The extraordinary story of how a curious creature baffled the world.” Moyal recounts the first specimens being sent back to the intellectual centers of western Europe (London and Paris, … Read more
So many books have been written about dinosaurs, but this one looks at a deeper history of another important group: our own. Beasts Before Us is “the untold story of mammal origins and evolution.” The Cenozoic is often dubbed “the age of mammals,” but the story of our hairy, milk-guzzling brethren goes much deeper into … Read more
Reader Michael Hiteshaw spotted some amazing folds this week while watching Kayak Session TV on YouTube. Though there’s a dramatic arc of “saving” a deer, both Michael and I felt our eyes drawn to the canyon walls where there are gorgeous folds in several sizes and shapes, with an emphasis on chevron folds: The … Read more
A reader of this blog recently recommended Michael Punke’s Last Stand. I thoroughly enjoyed his novel The Revenant, and so last week I started the audiobook version of the nonfictional Last Stand (2007). Last Stand is subtitled “George Bird Grinnell, the Battle to Save the Buffalo, and the Birth of the New West.” Prior to reading … Read more
Here’s a look at some of the wild critters that have been visiting my yard this year: [youtube=”https://www.youtube.com/watch?v=hh8muzLOE54″] The video’s organized in alphabetical order, so it starts with bears, and ends with a walking stick insect. See how many you can identify! Plus, here’s a compilation of 125 still photos of black bears from June … Read more
Rathlin Island lies north of mainland Northern Ireland, a few miles offshore. I spent three lovely days there this past summer, investigating the geology and appreciating the wildlife (puffins and other sea birds, and seals). The geology is pretty straightforward: Paleogene basalt overlying Cretaceous “chalk” (really not so chalky here – technically, it’s the Ulster … Read more
The news yesterday of 3.7 Ga stromatolites in Greenland prompts a closer look at 3.22 Ga microbially-induced sedimentary structures in the Barberton Greenstone Belt’s Moodies group sandstones.
The isle of Jura in Scotland is where George Orwell wrote 1984. It’s just across a narrow channel from the eastern side of Islay, where I spent four lovely days geologizing this summer. Looking across the gap, you can see a cluster of prominent mountains on Jura. These are the “Paps” of Jura, and they … Read more
Occasionally, our big windows get in the way of birds. The latest casualty was a hairy woodpecker, Leuconotopicus villosus. While it’s sad that our home being where it is caused the end of this bird’s life, its body was an opportunity to teach my son something about wildlife and ecology. We have a motion-sensitive wildlife … Read more
I just finished an interesting book with a provocative title. How to Clone a Mammoth, by Beth Shapiro, is a readable, sober assessment of de-extinction, the idea of bringing back extinct species through a variety of techniques. She defines very clearly at the outset that the purpose of de-extinction is ecological – to restore critical … Read more
Archaeotherium skull, on display at the Royal Tyrrell Museum in Drumheller, Alberta: I love these beasts since I first encountered mention of them at Badlands National Park, and reading them dubbed “grizzly pigs” in the excellent book Cruising the Fossil Freeway really stuck with me – these were pigs filling a predatory ecological niche we … Read more
I got word yesterday that the fisher, a medium-sized mustelid (Like a marten, an animal that I’ve seen once up in the Adirondacks of New York), has begun re-colonizing wild parts of Virginia. This is pretty exciting news – a friend from high school shared the image below with me: That’s from a wildlife camera … Read more
Last week, we had two wildlife deaths at Fort Bentley. The first was a mole (cause of death unknown), and the second was a screech owl (hit by a car). Here’s the mole: A look aft, at the digging apparatus: What astonishing “paddles” it possesses! There forelimbs are easily five times the size of the … Read more
It’s been a busy week. Hardly any free time. Here are a few pictures from my yard, taken this morning. Please accept them in lieu of a real blog post: Eastern cottontail: Mountain laurel: The cicadas are trilling in a mad, constant, siren-like noise. It’s intense, and otherworldly. Talk to you later…
Callan begins a week-long recounting of his five-day backpacking trip from the Cape of Good Hope to Cape Town, South Africa, along the Hoerikwaggo Trail. Today, we examine scenery and logistics of the trail.
UPDATE: This isn’t really a bat fly. It’s a deer ked. Back in October, I was weed-whacking in the yard, cutting down some 1-meter-tall grass and then picking up bundles of the fallen grass to put on our compost pile. I was out in the yard doing this for about an hour, then I came … Read more
Last summer, my wife and I spent some time in the Canadian Rockies. One of the things we did was to take a three-day backpacking trip to Floe Lake, in Kootenay National Park, British Columbia. We picked a rough couple of days for hiking – We got a lot of Canadian Rockies precipitation out there: … Read more
This is Dyer Island, off Gansbaai, southern South Africa, a little west of Cape Agulhas: Those are seals, a huge, crazy crowded colony of Cape fur seals. They are loud. They create a God-awful stink with all their fishy excrement. It was like being in a BBC nature program to see this firsthand. I could … Read more
The charming rock hyrax, a cuddly-looking fellow whose nearest living relative is the elephant: This is in the coastal town of Hermanus, a lovely place for whale-watching, in season. We were there at the wrong season, but the hyrax provided a mammal sighting that made us happy. The little fellow seemed to really be enjoying … Read more
