Budgie screeching and behaviour
I'm looking after a small dog for a few weeks and i've noticed that when Ruby is out and about he will come dangerously close to the dog and then quickly fly off. He also does that with my cats, luckily they are very laid back so don't find any interest in him becoming their lunch. Also when i leave the room he will start making this screeching sound, sometimes its just at a random time, and he doesn't look scared or anything.
Is he trying to annoy the animals around him? And is he maybe annoyed?
