Yard list 2021

It hasn’t been a good year for much, but I did get a lot of birding in. Traditionally, on new year’s day, I post my “yard list” from the previous year: a list of all the bird species I’ve personally observed from my yard. At my new house, I now have a full calendar year of observations. You’ll recall I moved to Albemarle from Shenandoah halfway through the previous year, …

How We Got To Now, by Steven Johnson

I was very impressed with Steven Johnson’s The Invention of Air when I read it last summer. So recently, I decided to sample another of his books, this one a six-part microhistory about innovations that altered the course of human history. The six are: 1) cleanliness/hygiene (specifically in medicine and drinking water), 2) measurement of time, 3) glass (think lenses!), 4) understanding of light, 5) refrigeration, and 6) the recording …

The Feather Thief, by Kirk Wallace Johnson

In 2009, a thief broke into England’s Tring Museum and stole hundreds of curated bird skins. The thief was a talented American musician attending school in London. He broke apart specimens collected by Alfred Russel Wallace and Lionel Walter Rothschild and sold the feathers to men who tie salmon flies (originally for fishing, but now an art form in its own right). The story of this crime is well documented by an author who became obsessed with solving the case of the missing birds.

The Evolution of Beauty, by Richard Prum

This fascinating new work by ornithologist Richard Prum re-examines sexual selection (mate choice) as a driving force of evolutionary change independent of (and sometimes in contradiction to) the mechanism of natural selection (environmental adaptation). Prum positions himself as a modern advocate for the ideas Charles Darwin expressed in The Descent of Man, and that Alfred Russel Wallace argued against in the years following Darwin’s death. In The Evolution of Beauty, …

Virtual owl pellet

Owls are nocturnal birds of prey that eat rodents and grasshoppers, digest the good stuff, and cough up the rest in compressed “pellets” of fur, bone, and chitinous exoskeleton. I found an owl pellet in my yard a few weeks ago, and imaged it using my GIGAmacro Magnify2. I rotated it around to get multiple views, as seen here. I’ve got both Flash and non-Flash versions of the GigaPan embed …

A virtual field trip to Rathlin Island, Northern Ireland

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 White Limestone). Here’s a suite of interactive imagery that you can use to explore Rathlin’s …

Who ate the woodpecker?

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 camera trained on our compost pile, and so I put the woodpecker’s body there in …
