While BBC America sticks with the classics — marathons of 2007’s Planet Earth (6am/5c) and 2018’s Planet Earth: Blue Planet II (5/4c) — National Geographic and Nat Geo Wild celebrate with three premieres. Here’s a primer:

Secrets of the Whales
This four-part stunner from James Cameron, which debuted on Disney+ last year, airs now as a marathon. Learn how different pods of orcas hunt and some male humpbacks create a new song each year and spread it around the globe. Plus, why families of chatty belugas stage an annual reunion and how clans of sperm whales (right) bicker in their own unique language!
