The show is in Japaneese 
but this is what is essentially going on. This owl is 20cm high. Then they bring to it another owl (different species) which is 35cm high. Our owl expands its feathers to become bigger and intimate the other owl. Then they bring to our owl another owl which is much bigger at 75cm. Our owl knows that it can not compete with this one so it tries to hide by pretending that it is a branch on the tree.
