Pages from a undated vintage notebook. Apparently, young Ray shot crows with a BB gun in his spare time, mapping out the location of his hunts. While researching to see if crows did indeed live on the island of Guam (which is identified on the map), I found this 2011 video about the passing of the last female Marianas crow.
P.S. I am having a hard time making a clickable link here, so you might have to cut and paste the URL until I figure it out. :(
