South of the ranger station, at 7:10, I came upon a daggetti busy excavating a hole in an aspen about 2½ ft. above ground. In a moment it was joined by another daggetti at the hole. Squawks. The first flew away. The second took a few pecks at the cavity, hitched about near it, tapping, and the flew off in the opposite direction from the first bird, catching an insect on the wing in the process. #5. I now went to nest #1, arriving at 8:10; no sign of the birds. At 8:25, a bird arrived at the nest - squawks - one emerged from the hole, flew to another tree, tattooed. 2nd bird approached hole, looked in several times, entered. Other flew off nearby. 8:30. - Much tapping by 2nd bird, probably feeding, about 50 ft from nest. 9:00 - Bird alights in tree near hole, taps. 9:03 - they change places.
