I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.
I will record lectures & all will be found at this link: github.com/rmcelreath/s...

Monk Parakeets Are Highly Social Birds, but They Slowly ‘Test the Waters’ When Making New Friends
The bright green parrots start with low-cost social behaviors—like sitting near each other without touching—when first interacting with unfamiliar birds within their species, possibly to avoid…

Juvenile songbirds acquire key life skills primarily from siblings and non-parent adults, with sibling influence surpassing that of parents in species with limited parental care. doi.org/g9578b
These songbirds learn more from siblings than from parents
Siblings are special. Whether a sibling serves as protector or tormentor, friend or foe, the relationship between siblings is like no other.
