I’ve got a new post up at 10,000 Birds on a study looking at changing populations of several hundred common species of birds in Europe and North America (mainly the US). The two subcontinents exhibit dramatically different patterns, as shown in the enigmatic graph above. Go to the post to unravel this intriguing mystery!

You’ve heard the phrase, “Nothing in biology makes sense except in the light of evolution,” an insightful phrase penned in 1972 by Theodosius Dobzhansky. I would like to add a second part to that phrase, and it goes like this: “… and, nothing in evolution makes sense except in the light of co-evolution.” This would…

You all know this happened. But there is some controversy over what kind of bird it is. There is no doubt whatsoever that the bird was a finch. However, what kind? Most likely a house finch, because they are common, and the most likely to live in a big auditorium thingie and not be fearful…

There are three kinds of books that count as animal (usually bird) guides. 1) A pocket field guide of the critters of a reasonably circumscribed geographical area, like the Peterson Field Guide to Birds of Eastern and Central North America. This is a small book that can fit in a big pocket, and a classic…

Feeding Wild Birds

When the Texas A&M University Press asked me to consider reviewing Feeding Wild Birds in America: Culture, Commerce, and Conservation by Paul Baicich, Margaret Barker, and Carrol Henderson, I had mixed feelings. Was this just another backyard bird feeding guide? That would be nice, but not too exciting. After all, feeding birds is just a…

We often hope, even assume, that technology will fix our problems. We also know that sometimes technology creates a problem. In this case, technology can help us fix the problem of needing to keep the fossil carbon in the ground by making use of the sun, but created the problem of vaporizing birds with intensely…

Changes in the daily variability of high and low temperatures in certain regions may stress wild bird populations. A new study of semi-wildish Zebra Finches demonstrates this. I have a post on the research here, at 10,000 birds. Have a look!

Loonacy

Check out my latest contribution to the bird blog 10,000 birds: Faithful Loons and Human Lunacy Every year there manage to be two Loons out in front of the cabin, up in Minnesota’s lake country. They nest on the same, ever-expanding semi-floating but occasionally shrinking nest over behind the point, so we can’t see the…

The Tuluver, A New Species of Bird

People were fascinated, excited, and some were enraged, by this awareness raising campaign of BirdLife South Africa. I might have preferred this modification:

The Birds At Itasca and Other Matters

When I studied the Efe Pygmies of the Congo, I discovered (and yes, it was me who discovered this amazing fact everyone now knows) that the Efe organize their space in elongated linear trails. They knew all about everything along those specific trails, and their knowledge of other trails was often very limited. If an…
