Flying around together. I saw a 4 w LB/K-Y for sure and she doesn't match the field list. Cyndy watched afterwards and reports nothing unusual. 17 April 0900 Mate guarding, drumming, 1 chase. 2 birds checked out The 86 Wolf hole together, so I climbed it. Empty, but nice chips. Gaping hole in back. Repaired. Alas, I hope they don't use it. Need a watch hole. 23 April 1100 2 birds went to the Wolf hole. One went in. They also use the Wolf black oak. Climbed - empty. 26 April 1530 Bird to hole 1700 Empty. 2 May 1530 Bird in hole on arrival. Climbed - empty. 8 May 1530 Empty. I'm beginning to have doubts. 13 May 1500 Empty. Really doubting.
