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

AI DID make a bunch of minor mistakes, but since I know the topic really well, these were easy for me to spot. What is the future of AI? I dunno. And should I trust the references it suggested? Seems like it, but...

Basically, something that would have taken me days to do on my own, AI did in minutes. I am gonna have to disclose AI use on the current paper I am writing... and the models in the paper were generated in a couple hours rather than a couple weeks!!

I didn't recognize this version of the equation, so I asked it to clarify. It backtracked and gave me the version I know, except better notation and easier to read than Lowson's paper. I would have used this version in my 2020 paper had I had it.

I am kinda intrigued / disturbed by the ability of AI to do maths. I am slow, it takes me hours to do simple things. Yesterday I asked AI for some help and it did an amazing job! Super fast. In the screenshot it has whipped out Lowson's equation in seconds...
AI comes up with Lowson's equation in a form I can use

Given that most signs in Canada are English message // French message, I assumed that in Quebec it would be similar (French // English). But no. Quebec, sir, where’s the English?

Happy to share this 'capstone' project from my time as a postdoc @umich.edu, where we show that hierarchically nested bursts of body-shape evolution may underlie much of perching-bird diversification over ~50 million years. Free access link here: rdcu.be/fuxB1

I'm pretty uncompromising on most first amendment issues but goddamn it posting fake AI nature videos ought to be a felony.

These birds clack their wing bones together to woo mates at night
During courtship, male scissor-tailed nightjars crack their wings together to make a sharp snapping sound. It's the result of colliding arm bones.

Males bang their wrists together to produce a loud 'snap' sound. They do this in multiple contexts, including copulation. For some reason my video of copulation won't post here... macaulaylibrary.org/asset/623341...

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.
