Today I had the windows open and I hear this guy talking away. (Go here if you want to listen to what it sounds like - it's a great sound and the site is full of info on birds.) I wonder now if Izzi wasn't hearing this bird through the window and answering? Regardless, it's fun all the way around. Fun to hear our cat talking to the bird, and fun to watch this guy crawl around the feeder and pull out fruit and nuts to chew on.
