Mystery bark

For several days now, off and on, I would hear what sounded like one of my chihuahuas barking. But the sound seemed to be coming from the back yard. And I was sure I had not let them out at that time. So I would get up and make sure they were not outside. Tonight Ken thinks he has it figured out....our parakeet "Maxy" is imitating the chihuahua bark!! I will be really paying attention now and hope to catch our parakeet on video making the barking sound! I think that is so cool!
