Hi, catmoggy.
I have a talker too. Chester talks to the birds outside and other cats. He starts in at sunrise, which is about 6 am here in the summer, runs from window to window off and on all day. He has the loudest meow I've ever heard. I wish he would be a little less vocal early in the morning. He even talks back to me. He's a sassy one all right. The other 3 just look at him like, "What is your problem?"
