My opinion about 3 videos!!
In this video, this adorable dog is covering the baby, maybe he is just playing or beeing part of something that we don't understand. Anyway, is an act of caring and I can even really think that he feels empaty. In this one, gorilla goes first in crossing the path. He stay still until the other integrants past without problema. If something happen, he is the one who is going to react in defense, and in not a very good way I have to say that this video is really the best I could find about a Chucao, it is sooo hard to find it in the wild, but it is a pleasure to hear it sing near the tent, is just amazing.
