It's been awhile since I've posted a photo on IG and FB. It's not for lack of photos! Rather, time, poor engagement on static images (compared to stories), and some general grappling with the state of social media held me back. I can't say that I've come to any deep conclusions yet, so in the mean time I'll try to sprinkle some images into my feed again.

Starting with this one - a Mule Deer that wasn't particularly concerned with me. In fact, maybe it was taunting me with that tongue sticking out!? Either that or it just needed a good nose lick, as deer are known to do.

Can we forecast earthquakes? Answer: partly yes! But don't think of it like your weather forecast.

Which part of the USA has the greatest risk for earthquake damage? Answer: surprisingly, it might be the eastern USA!

And what about "earthquake weather"? And did you know the Richter Scale was actually phased out years ago?

Learn about this, how and why earthquakes occur, and much more with earthquake geologist and science communicator extraordinaire Dr. Wendy Bohon, in the last episode of Nature's Archive Podcast! Check the comments for details. 👇👇

A Desert Cottontail's Ear is quite fascinating.

So, before the Cottontail, as you may have noticed, I haven't posted many photos (or much at all) the last couple of weeks. I've been generally questioning social media lately (well, people who know me know I've had long standing concerns with this medium).

Deciding to post here means passively agreeing with the algorithms that prioritize engagement over accuracy. Algorithms that achieve that goal by prioritizing enraging and angering content that divides people. Thankfully, we have *some* control by selecting who we follow and what we click on.

It's long been known and well documented that a material amount of the engagement on most social media networks (some more than others) are actually bots, many of which are run by international state-run organizations seeking to leverage these algorithms to further divide us. And in recent weeks, it has become clear that our own government has this same power, though in their case, propagandizing is the motive, and dividing us is just a byproduct.

I don't have the answers, but I am trying out 🟦sky, which seems to have better controls against these activities.

OK, so check out this Desert Cottontail! As cottontails go, they have very large ears, and you can see the veins that it can use for enhanced thermoregulation by dilated or constricting blood flow. These cottontails, unlike the eastern counterpart (see second photo) live in warmer climates where heat dissipation is more important. Just compare the two and you'll see for yourself!

I wrote more about this in my Nature's Archive newsletter - a brief, free (and spam-free) monthly offering that you can subscribe to on my website (see my links).

Our latest Jumpstart Nature production landed this week!

There's a silent invasion happening across the world, even in your neighborhood. Invasive plants and animals are taking over, reducing nature's productivity, and hurting biodiversity.

Sometimes, we're unwitting co-conspirators, transporting plants, seeds, and insects when we travel, garden, hike, boat, or camp. Many common exotic garden plants easily escape the confines of your yard - plants like English ivy, tree of heaven, and more. Invasive plants and animals can threaten biodiversity, food supplies, and everything from baseball bats to wine. They can also increase wildfire risk and intensity.

It's overwhelming - but you CAN make a difference, and it is not as hard as you might think.

Learn how in the latest Jumpstart Nature podcast episode, featuring , Dr. Sara Kuebbing, Emelie Swackhamer, and of course, as your host.

‼️NEW EPISODE ALERT ‼️

Two topics in one today: Acorn Woodpeckers and Acorn Masting!

Did you know that Acorn Woodpeckers can fly catch? They fly from a perch and catch insects on-the-wing. But they are perhaps best known for caching huge quantities of acorns.

But there is much more to this bird than that - they have a complex social structure, a wide variety of vocalizations, and much more that make them fascinating ecosystem engineers.

And if one discussions Acorn Woodpeckers, its impossible to avoid the topic of acorns. Have you ever noticed that some years oak trees produce huge quantities of acorns? This is called masting, and 2024 was a mast year in much of California.

Our guest in the latest podcast is perhaps the world's leading expert on Acorn Woodpeckers, and he studies the science of masting as well. Hear from Dr. Walt Koenig in the last Nature's Archive episode!

Today I Learned...there is a World Magnetic Model that is periodically updated.

Of course, this makes sense. It's well known that Earth's magnetic field meanders constantly, and sometimes even flips entirely! That's right, the North and South poles can switch.

Evidence in the magnetic alignment of sub-sea rocks show that this happens roughly every 200,000-300,000 years. It has been 768,000 years since our last reversal. But don't read too much into that. Sometimes it takes millions of years to flip.

And a magnetic model is important for GPS and other navigation. Check it out:
https://www.ncei.noaa.gov/products/world-magnetic-model

One other thought - I've often wondered about what natural and man-made disruptions such a flip might cause. Will birds still migrate efficiently? The magnetic field helps deflect certain solar radiation - what happens when the poles are meandering through the middle latitudes? Some of these are answerable questions, but perhaps this would make a good Nature's Archive episode to explore in more detail.

The glassy surface, tumbling waves, and calming sounds of the ocean hide a harsh reality. In just a couple of years, an incredible and vital sea creature, the Sunflower Sea Star, started to melt away, with nearly 5 billion disappearing. 🌊🌟

The result: a keystone species gone from their preferred kelp forest habitat.

While the causes of the mysterious Seastar Wasting Syndrome is still not fully understood, work is already underway to re-establish Sunflower Stars. And championing a huge part of this effort is the Sunflower Star Lab in Moss Landing, California.

Great progress is already being made, and the latest is an onsite interview with the some of the volunteers of the Sunflower Star Lab, - Reuven Bank and Andrew Kim.

Learn what it takes to raise sea stars in a lab, why sunflower stars are so fascinating AND important, and what the future may hold.

Sophie Osborn has helped reintroduce Peregrine Falcons, California Condors, and Hawaiian Crows during her time as a biologist. With these incredible opportunities have come stories of success and inspiration. Also, there are stories of challenges, and unique insights into how the challenges these birds face are often the same challenges we people face, too.

Sophie was kind enough to join me on the latest to discuss her insights, as well as her new book, Feather Trails, published by

This conversation was so insightful and we covered so much, it was really hard to put a few social media slides together that cover the breadth and depth Sophie offers. So please check it out in the usual podcast places. You know where to look!

A quintessential sight along central and northern California coasts! It's a group of California Sea Lions hanging out on the docks! They love to sun themselves, often pointing their heads towards the sky (like the one on the far right is doing).

Sea lions are awkward on land, but spectacular swimmers! I've read that they can stay underwater for 10 minutes at a time (one source claimed 30 minutes!), go as deep as 800 feet, and swim at speeds in excess of 25 mph! To put that in context, the fasted mile ever run by a human is just under 4 minutes, or 15 mph.

During my trip to Costa Rica, I though about several times. I had the good fortune of interviewing the Save the Frogs founder Dr. Kerry Kriger on my podcast (episode 48 if you want to check it out!), and he helped open my eyes to the perils face by frogs across the globe.

That said, Costa Rica remains a frog paradise (though there are challenges there, too). This Strawberry Poison Dart Frog is one of the most striking frogs my group saw. My kids said it was wearing purple pants and had a red body. 🤣

Honduran White Bats (sometimes called ghost bats) almost look like tiny cotton balls if you aren't looking too closely! This group was found roosting under a leaf in Costa Rica. Not wanting to disturb them, I crouched underneath, illuminated them (the biologist with us said it was OK), and snapped a couple wobbly photos pointing my camera rig straight up while in a deep squat.

We thought we were super lucky to see these uncommon bats, but actually stumbled upon two more about an hour later!
