We're bringing back one shell of an episode with today's encore. What's a tortoise? What's a turtle? Why do they live so dang long? What's up with their junk? Wildlife biologist and testudinologist Amanda Hipps studies gopher tortoises and dishes about turtle nomenclature, cliques, dicks, behavior, burrows, evolution, habitats and more. If you don't dig tortoises yet, you're about to fall deep into a turtle tunnel in love with them.

You love pigeons. You might not know it yet. Espionage! Fancy breeds! Internal GPS! Weird feet! Should you be afraid of them? Should you adopt one? Pigeon advocate, comic artist and author of “A Pocket Guide to Pigeon Watching,” Rosemary Mosco finally joins to answer all of our questions in a beautifully mellow and melodious wall-to-wall pigeon exploration. I loved every minute of making this one and if you stick around for the secret, I’ll take you behind-the-scenes. Listen, then sit on a bench and watch your new friends.

Columbidology (PIGEONS? YES) Part 1 with Rosemary Mosco

Do trees have feelings? How do they talk? Which trees can you use to make syrup? Do bananas really grow on trees? Possibly the world's most enthusiastic tree expert, J. Casey Clapp, explains what makes coastal redwoods the coolest trees, how roots communicate with each other, and why a tree is like a cup of tea. Plus: bonus guest appearance by our friends (and the trees’), fungi.

Smologies #42: TREES with J. Casey Clapp

Come along like a frog in my pocket for an adventure to see an eclipse. After last week’s Heliology episode on the Sun, I rushed out of state to see what the fuss was about and to witness my first ever total eclipse of the Sun. Did it go as planned? Of course not? Did it work out? You’ll have to listen. We’ve got: a rollercoaster of emotions, last-minute pivots, chats with strangers, highway scenery, hope, anxiety, awe, and tears as we see if my seven-year wait for totality pans out.

Field Trip: I Chased the 2024 Eclipse with Umbraphiles

Sunset flimflam! Auroras! Eclipse tips! Let’s get to know the center of our solar system, the Sun,  as the April 8th eclipse approaches. What is it made of? How big is it? Will it explode soon? Why can’t I stare at it? And why is it wearing sunglasses? Dr. Michael Kirk and almost-Dr. India Jackson are brilliant and charming Heliologists who have both worked with NASA’s heliophysics departments. Get to know them and also the giant hot plasma ball we revolve around. You’ll never (not look at it) the same.

Heliology (THE SUN/ECLIPSES) with India Jackson and Michael Kirk

Spine mysteries, face purses, limericks, flim flam, flags, dive bombs, sibling rivalries, and more! The warm and wonderful pelicanologist Juita Martinez studies these glorious dinosaurs and shares what it’s like to hold a floofy baby sea bird, how these birds’ ecosystems are being restored, and what she loves about being in nature. Also: How much fish can they fit in there, anyway?
