Well the Whoopers were back again today. It seems that these are two males. The local Wildlife officer said there is a predominance of males in the Eastern population. One bird is the 37th bird hatched from 2007 and the other is the 20th bird hatched from 2013. They leave the immediate area or at least go out of sight about 1/2 hour before dark. As I find out more details about these birds I will share.
