Summary
Written by a model from the transcript; not yet reviewed.
This episode explores how surprising natural phenomena connect to everyday human systems, from the origins of modern color standards to the bizarre social structures of underground mammals and the countless colloquial names for a versatile North American fruit. The host and guests examine how an ornithologist's quest to classify bird colors inspired the Pantone system, why naked mole rat colonies rely on scent-based chemical control to maintain order, and how a single shrub acquired names ranging from serviceberry to chuckly pear.
- Check online museum archives to view historical color guides like Robert Ridgway's 1886 nomenclature book. 12:38
- Recognize that blue jay feathers appear blue because of microscopic structural features rather than true pigments. 15:31
- Search foraging apps like iNaturalist to identify local species of Amelanchier trees in your neighborhood. 1:03:37
Chapters
- 0:03Show Intro and Host Teasers
Rachel, Liz, and Alexis introduce themselves and tease their weird facts for the episode.
- 1:01Naked Mole Rat Scent and Social Hierarchy
Rachel discusses the mole rat’s unique chemical signaling, how queen pheromones control reproduction, and the colony’s social structure.
- 3:10Birds Inspire Pantone Color Naming
Liz explains how the Eurasian teal bird gave its name to the color teal and the broader history of bird‑named Pantone colors.
- 57:38Exploring the Sweet Plum-Like Fruit
The hosts discuss a mysterious fruit that resembles a small plum and belongs to the rose family.
- 58:56Unpacking the Shad Bush Mystery
They dive into the confusing name of shad bush, its origins, and seasonal timing.
- 1:00:43Etymology of Amalankier and Related Species
The conversation shifts to the Latin roots, Provencal origins, and meaning of Amalankier and related berries.
- 1:02:12Flavor Profile and Culinary Uses
They describe the taste of the berries, compare them to apples and blueberries, and talk about cooking challenges.
- 1:03:13Planting and Foraging Tips
The hosts share plans to plant berries at home, label them, and encourage listeners to forage using iNaturalist.
- 1:04:52Bird Interactions with Serviceberries
Discussion of how birds, especially cedar waxwings, interact with the berries and the impact on foraging.
Highlights
- 3:10
Birds Inspired Pantoneinsight
An ornithologist trying to standardize bird colors created a comprehensive color dictionary in the nineteenth century, which later helped inspire the creation of the Pantone color system.
- 14:13
After publishing an initial guide with 186 colors, the ornithologist self-published an expanded 1,912 version containing 1,115 distinct color standards.
- 15:31
Structural Color in Blue Jaysinsight
Blue jay feathers do not contain blue pigment; instead, microscopic air pockets in the feather structure scatter blue light while letting other wavelengths pass through.
- 23:22
Naked Mole Rat Oxygen Survivaldata
Naked mole rats can survive in oxygen levels as low as five percent for hours without showing signs of distress, a tolerance far exceeding human limits.
- 29:47
Eusocial Mammalsinsight
Naked mole rats and DeMarland mole rats are the only known mammalian species to exhibit true eusociality, living in highly organized colonies with strict hierarchies.
- 31:09
Tunnel Dominance Testsstrategy
Mole rat social ranks are so clearly defined that researchers can determine dominance simply by observing which individual yields when two meet in a tunnel.
- 34:43
Queen Scent Controlinsight
Naked mole rat queens produce a specific chemical compound that acts as an olfactory birth control signal, suppressing fertility and breeding behavior in other female colony members.
- 46:09
Countless Names for One Fruitinsight
The edible fruit of the Amelanchier genus is known by dozens of regional names across North America, including Juneberry, serviceberry, Saskatoon, sarvis, and chuckly pear.
Quotes
“the color teal is named after the Eurasian teal, which is a bird.”
Unnamed speaker · 5:52 “They have 1,200 olfactory receptor genes, which is, I think mice only have about a thousand and humans only have a few hundred.”
Rachel Feltman · 35:23 “When they sprayed it in cages, basically they took non-breeding females and, you know, took them out of the colony, put them in cages with males. And when they sprayed those cages with this compound, there were no pregnancies.”
Rachel Feltman · 38:08 “The missing link. Because I was sitting there being like, imagining the horrible American accent that had turned Sor- Sorbus and Service.”
Rachel Feltman · 54:00 “They taste like an apple and a blueberry and an almond had a baby.”
Unnamed speaker · 1:02:12 “My book is called Happy Snacking, Don't Die.”

About this episode
Alexis Nikole joins the show to talk about the heinous etymology of the juneberry (if that's even it's real name...). Plus, Liz Clayton Fuller returns to explain how birds are behind Pantone, and Rachel details the ins and outs of Naked Mole Rat society -- and what it has to do with their STINK.
