The hollow belly of the red fir seems like a safe and snuggly place.
It's quiet in there and it's dry, even though frass rains down 24/7 from the gallery of wood ants above.
Bob's observation that "the cavity . . . looks like a bear den" was right on the money.
Ten hours after we left the scene a bear peeked into the cavity.
In the next week the opening framed a robin several times,
and a chipmunk made a brief visit.
Then a small bear paid a visit,
and toppled the camera.
The camera took pictures of wood ants on thr floor of the den until we came back and reset it.
If I had a time lapse camera with 5 months of battery power, this would be a fine place to monitor a sleeping bear.
