I want to thank John Jonas for giving me the location of this bird and for others who shared it before him  Brand Gulstad and Wilmar Fernandez who I believe originally found it.  The bird is located near the children’s maze on the 3 mile trail at the Arboretum,  It is just south of the maze and could be on either side of the road. We watched him fly back and forth several times across the road..  He was easily located if you know his call at all.  I hope that he finds a mate.  Here is a link to some photos.  https://www.flickr.com/photos/ronsthoughts/with/27354289413/
