Not today, but one time I went in that store I spoke to someone about him. They put the sign because they have all random customers who come and stick their fingers in his cage and bother him. They said the staff are quite fond of him and at least one of them can handle him quite easily.The sign saying that bird bites makes me giggle. Technically to a stranger you could say the exact same thing about Happy. She may be tiny but that beak can hurt. If she does not know you the first time she meets you she is going to test you. Depending on how you react sets the stage for how she behaves. She is going to fly to you, don't be like my sister and duck and squeal...just don't. She may give a test nibble. It is actually gentle, but how you react to it will determine how she behaves around you. If you act like she is afraid, she will really try to bite you. If you stay calm, and tell her no she will not try to bite anymore. This bird also reads emotions like no other. You cannot handle her if you are in a bad mood, she picks up on it and acts out. I have not went to see her since I came home, we have a great relationship but I know she will pick up on that I am off and the demon will come out.
