Chickadee Nest Observation - Thursday, A.D. - July 6, 1902.
(by Claire Madison and Mr. Denison)
This Chickadee nest is in the half-trunk of a dead lodge-pole pine tree. (The opening looked like a big keyhole!)
This tree is along the roadside, in a meadow. There was no underbrush nearby. The nest was up about 5 feet from the base.
The female Chickadee flew in and out constantly. Usually she stopped at the opening a quarter to a half minute - just long enough to shove the food in, and dart away after more. Sometimes this went on and on at one-minute intervals. Two trucks went by, but that didn't throw Mrs. Chickadee off schedule.
One time she heard a Jay, and didn't come near the nest for nine minutes. One time she flew from tree to tree in a great semi-circle, and was away four minutes. One other time she stopped to preen for a minute. Otherwise - she was in and out - in and out.
This Chickadee flew one time to the ground, among the grasses, the time she was away the longest. Other than that, she foraged among the nearby trees - almost never higher up than 20' to 25'. She always stopped at the living tree that was right along side the old dead trunk - then fluttered in - and out.
Just as we left, we looked in, and up popped the head of an almost full-grown young Chickadee - then down he dropped so he'd be hidden again.
