One of the bireds has taken to sing to me a different song (other then the 'caw'!). I have not heard of a Scrub Jay singing any other song... So, I finally brought out my small camera, small enough so I won't scare him/her. In this video, he first stands on top of my new chicken coop (you can hear them chuck-chucking). Then I talk to him and 'coo' at him to try to encourage him to do his special song. Finally, he sits next to me and sings.... what a wonder!
