(10ct) 1530 Well, I thought I Found it... Ends up there are 2 holes up here. The more likely one was empty. The other was all grown over + rotten + deep so I couldn't check it. No young babies in either (but could be eggs or quiet babes) No bird in hole on arrival.
4 Oct 0850-0915 Watch holes - twice a bird landed on the hole branch just around from the lower hole - I left blind to check - but there's no hole there. Back to blind to watch 0930-0945 Birds in the immed area near the holes - but no hole visitation. Some seemed preoccupied w acorns.
