It’s fun to get a deeper dive into things more than just basic facts.
The lead scientist that discovered owls can hunt using only their ears later went on to do more groundbreaking research on whale communication. It was interesting to learn about the test enclosures and the methods used to see how much vision vs hearing played into hunting. There were also some great stories about how training owls is as much fun as training cats.
I’ve also read some papers on how other birds of prey hunt. They analyzed different vectors of attack and studied where the birds focus their eyes when they are attacking.
Just lots of insights on anatomy and behavior in general like how they time extending their talons and the orientations of the toes to maximize catching prey.
Even egg laying and hatching or growing feathers are all complex and amazing processes, and it’s a miracle all these things evolved to work the way they do.
The amount I’ve learned about owls this past year is crazy, and I still come upon new things all the time.
