I have taken another look at the map of the Singer Tract discussed in my previous post, and I find that I was so focused on John’s Bayou that I overlooked nests I and V, which were located near Mack’s Bayou. Nest I is dated May 14, ’34 and Nest V is dated May 10, ’35. The four nests found in 1935 are listed in Bales (p. 64.) Tanner mentions only two of these five in his monograph.
While it doesn’t change the overall point of the post, three nests were found in the John’s Bayou area in 1935, and I was mistaken about the possibility that there might have been a fourth.
