The idea that there is a remote part of Earth where dinosaurs still roam has been a popular idea since the dinosaur mania of the late 19th century. Today I will go in search of large reptiles and an unusual living avian dinosaur found in the depths of the Amazon Rainforest, the Hoatzin. These birds will help me explain why birds are living dinosaurs and what traits they still retain from their ancestors. Remember to subscribe to BioBush after this!

I try to achieve the most well researched content I can, that said it is impossible to create content that is exhaustive on a given topic and therefore I implore you to investigate a given topic further.
Welcome to Ecotasia! On this channel you can find wildlife footage and short documentaries on the natural world. I am an early career biologist who was inspired by the likes of the BBC Natural History unit, PBS, and Animal Planet as a child and then more recently by various nature YouTube channels to share my love for animals and nature. My goal is to document and highlight the interesting ecology and behavior of organisms I encounter, as well as cover and elucidate conservation and biological topics. Please Subscribe so you can join me to marvel and to learn twice a month.
