I study hummingbirds and owls, and the sounds they make, or not, with their wings.

Myiarchus flycatchers ordered by size and intensity of yellow underparts. When it comes to flycatchers, differences between species tend to be very subtle. Impressions of size and color in the field can be quite subjective, but the differences are real.

For @msnownews.bsky.social, I wrote an article about how ICE Watch is grounded in sociological theories of violence prevention.

The reality is that most men will only commit public violence in extremely specific scenarios and ICE Watch disrupts the conditions necessary for escalation.
Opinion | I'm a Minneapolis sociologist who studies violence. Here's how ICE observers are helping.
Research into how violence occurs shows that disapproval from the people around you can help reduce it.

RIP to the incomparable Jane Goodall, who embodied the best of humanity.

Her rich legacy included becoming friends with Gary Larson after he drew this cartoon. (She was delighted by it, even though many at the time thought it was terribly offensive to her.)

Pick an idiom: "more than meets the eye", "beauty more than skin [feather] deep" etc.

In work led by Rosalyn Price-Waldman, we describe a hidden (and ignored!) black or white layer found below the visible surface of bird feathers which helps make bird colours so striking!

*Sigh*. Caught a grad student using AI to generate fake citations today. Need to figure out the best strategy to make this a teachable moment. Maybe "gentle teasing"? "Strict warning"? Unclear which will work best in this case.
