Ep. 25 - The Eastern Screech-owl

Steve and Bill start off 2018 with an episode about Eastern Screech-owls. The guys talk about its unique dichromatism, adaptations for hunting at night, and even call one in during the podcast. Make sure to wear headphones for this one- the birds calling in the distance aren't always easy to hear. Steve also gets really nervous about being killed by a bobcat for some reason... Enjoy!

It wasn't directly stated during the episode, but Steve didn't use a single typical peer reviewed publication for this episode (not for a lack of trying though). He stuck to field guides, birding books, and old observational papers. It's a bit different than usual, but there's not a wealth of publicly available peer reviewed literature covering Eastern Screech-owls. If you have any interesting papers, be sure to send them our way!

Steve says pronounces the "L" in palm at 34:50... he doesn't understand how silent letters work
