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

I like to have AI do all my push-ups and sit-ups for me! So much easier than doing it myself.

I'm not sure what's going on with my university's schedule of classes... they seem to be planning classes for the afterlife? But when I click through, the BIOL major is no more... #UCR

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.

Nice! It's handy that maple syrup and whiskey are the same color, so nobody can be sure what you've got loaded up.

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.

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.

false, odors are molecules small enough to volatilize -- about 12 carbon atoms max. So no, the smell of shit is not shit itself

The topic is how owls hunt prey thru snow. I learned that snow can reach up and grab sound that was just minding its own business, passing nearby (called "Grazing incidence sound absorption").

Paper is probably salvageable but my naΓ―ve model isn't. Editor replied rejecting paper w/o prejudice. I've got some work to do on it, but I'm actually excited by it all. I learned a concept w/ strong relevance to my work, and I have an idea for additional experiments in this area as a result.

Today Sr. author again replied, he'd read my paper, he provided a short critique, named additional concepts, and answered a couple questions. Don't fully understand concepts yet but googling tells me what I need to know: Weird result not so weird, and model in my paper wrong. 3/

Looked @ refs, saw senior author, googled him, realized this concept might explain my weird result, then emailed, sketching result. Got very prompt reply; realized my 'weird' result probably not so weird. Emailed editor at journal to notify, and sent Sr. author draft of submitted paper. 2/

Sadly, the companion to this piece, on which males had paternity, did not work. Sean found nests in this population, to try to measure paternity. However, a litany of problems (microsats weren't variable, windstorm caused nest failure, too little DNA in the sample) mean this part didn't work.

Our latest paper is out: Sean Wilcox measured the 3D kinematics of Black-chinned Hummingbirds performing one of their courtship displays. Lots of evidence of flight performance tradeoffs!
