1985 Mark Stanlack M. formicworma Gazebo H/NHR 28 June 1400 - 1415 looked unsuccessfully for 2nd nest. 3 July census: 718, 942, 1103, 1104 Could not find 2nd nest. 5 July 1230 - 1300 Could not find 2nd nest. late July tried again - no luck 19 Aug 1500 - 1530. "Census" Saw 942, 1103. I played the power struggle tape for about 5 sec. Immediately, 2 birds appeared at the old nest (in the knothole). One bird looked inside before flying off. I watched the hole for a while, but no action. I later climbed the tree, but couldn't reach the bottom of the hole. Keep an eye on this group. They are due for another nest 21 Aug 1300. No response to hello from Knot-hole or any other hole. This group has some acorns still stored from last year.
