Catbird Mimics Dog Barking

We have a resident Catbird and I have loved listening to his varied whistles, songs, warbles and other strange calls. Yesterday I even heard him mimicking the dogs barking! At first I thought it was the neighbors dog, then I went out on the deck and realized it was the Catbird....truly amazing how much he sounded like the little Bichon next door! I wish I had gotten a video of the call, I did get some photos at least.
