A great summary of our recent warbler hybridization work in PLOS Bio.

New story on the Avian Hybrids blog! A colorful mess: Widespread exchange of pigmentation genes across the Parulidae phylogeny avianhybrids.wordpress.com/2026/03/11/a-c… Based on the PLoS Biology paper by Kevin Bennett and his colleagues | #ornithology

@evornithology Scaup (both? hard to tell), LTDU, maybe some of the LTDUs in the back are actually BUFFs, COGO, WWSC, REDH, COME

Hey you! Yes, you! Do you like Weird Ducks™️ but don’t want to freeze your ass off standing next to a lake in winter? Well now you can bird the Oswego Harbor from the comfort of your living room! How many species can you pick out? #binoblast

@mattyglesias "Substantially" actually meaning "several major mitochondrial haplogroups." Not the same thing.

@capitalweather Shoveled and salted at 7am and 4pm, salted at 9pm. Cleared some slush this morning. Totally clear today.
English
It was pretty simple: shovel several times (didn't even need salt), including at the end of the storm. Those who did this, and we've heard from dozens, had great results. If you only shoveled early in the storm and then left it til today, yes, now you're dealing with cement.

@juliet_whiskey_ @capitalweather Don’t know why people don’t understand they must shovel and salt (multiple times) during the storm

@mattyglesias Consider de-paywalling this so your critics who won't want to subscribe can read the whole thing and respond. Will probably net you more subscribers.

@bendreyfuss I've lived in Bethesda, Petworth, College Park, Alexandria, now way out in Woodbridge. Always tomatillos in the stores. Where are you shopping for tomatillos?
English
In all the months I have lived in DC I have not seen one tomatillo for sale in a supermarket. But tomatillos are delicious, and the departed DC beltway sickos don’t know what they’re missing

@bendreyfuss This is the way to go. Cheap Logitech Mouse has revolutionized my working from coffeeshops.
English
I looked into the Apple external trackpad but 1) it’s a zillion dollars so go fuck yourself apple, and 2) people don’t seem to like it very much.
It’s the $20 Logitech mouse for me!

Why do people like laptop stands? You end up typing at some absurd angle. It helps with your posture because you aren't hunched over like some, well, hunchback, but it's a very unintuitive hand position.

@evornithology Velvet asity got lost on the way to the manakin party.
English
Just a quick reminder that asities exist. Endemic to forests of Madagascar, they construct pendulous nests and would like you to know that, yes, they know they have a little something on their face.
English
No big deal, just...

Today in @ScienceMagazine, we report a new DNA editing technology to seamlessly write massive changes into the right place in the human genome. The reason gene editing hasn't transformed human health is that current gene editing technologies like CRISPR are very limited. The problem with CRISPR is that it cuts up your DNA, and then hopes that unreliable cellular DNA repair will make the wanted edit. @geochurch famously called it genome vandalism. More precise versions of CRISPR only edit less than 100 bases - often only a single base. Therefore, it's not suited to make large changes safely. However, most diseases are not the result of mutations in one location. Instead, their causes are spread all across the 3 billion base pairs in the genome. We found bridge RNAs in bacterial “jumping genes” that allow us to make safe and arbitrary changes (insert, cut out, or flip) to every nucleotide within (up to) a 1 million bp sequence in your DNA. In the paper, we show that we can correct the disease-causing DNA repeats that cause Friedreich's ataxia (which is a rare neurological disease). The same approach could be applied to Huntington’s and other repeat expansion disorders. At @arcinstitute, we're working towards a full Turing machine for biology. Evo, our DNA foundation model, helps us design the optimal healthy DNA sequences. And Bridge recombination gives us the ability to seamlessly write these changes into the right place in the genome. This work was a wonderful collaboration with my @arcinstitute cofounder @SKonermann and led by the indefatigable @ntperry13, alongside our amazing bridge editing team: @BartieLiam @dhruvakatrekar @Gabogonzalez515 @mgdurrant @james_jw_pai @AlisonFanton Juliana Martins Masa Hiraizumi @chiaroscurale @hnisimasu

Any guesses as to the “Latin American” birds depicted by Frederic Edwin Church in his 1877 El Rio de Luz?
English
@TheBirdist Digging in and building on all the work I've done thus far to learn the birds in G. Have to stick with it.
English
For the rest of your life you can only go birding in one of these regions, which one are you picking?

@jesseGlab @cowbirdlab Looks like it's the faculty director of Macaulay Library. I guess since Mike Webster is retiring. Not the Lab of O director.

Today was the fake holiday of National Dive Bar Day.
Here’s a list of DC’s dive bars (categorized by opinion of whether it is in fact a dive bar)

What does this mean for plumage introgression? We may have caught this situation as gene flow is temporarily slowed at the river before continuing. Or it could point to geographic variation in female preference or some other unusual scenario. Either would be pretty interesting.
English
Finally, we ran demographic models to estimate gene flow and found a similar result. Higher gene flow upriver than downriver. But in both areas, there is plenty of gene flow across the river.
English
New paper published! How does a mid-size river impact gene flow and population structure, including when there is an adaptive sexual trait present on one bank but not the other? With Peri Bolton, @robb_brumfield, Jerry Wilkinson, and Mike Braun.
