I have a cockateil who is displaying very strange behaviour that I have not seen one do before. He goes all stiff points his tail straight out and makes a strange sqeeky chirping noise, he does it every now and then, it's almost like he is trying to get your attention by striking this pose and making this noise.
Is that all it is???Has anyone elses bird done this before and if so do you know why????(Felix is healthy)
