Olaf and Zircon have been in our home less than a month. When they make certain noises they want something. We are learning that noise....well I am not so much my husband. He will tell me they have been loud all day. I ask where they are when they are talking to him. Door of cage is for attention (sometimes all they want is for you to sit by the cage even), food dish is they don't want to eat the pellets and want more seeds and standing by water chirping water is there is a seed in the water dish. Birds are trained to communicate, now to train the husband to be a good budgie daddy.
Olaf also is interested in our one dog...they stand checking each other out. One from top of buffet one from floor...very cute:-) both unsure of other. But neither too scared.
