Great chart!
FWIW I'd add flipping rocks for bugs in late April and May, with ants and pulling bark from down logs after such bugs strong in the spring also. You can hear them, but it is a much quieter activity than I realized from looking at where they have worked a stump or log, or flipped rocks on a hillside. They pick at bark and rotten wood with claw tips and lick escaping bugs rather than bash it.
Re dandelions: I've seen more bears in dandelion patches in spring than later in the year.
In later summer up high they really go after a large pulpy-stalked big leaved plant near timberline that I recognize but don't have a clue as to its name. Have watched black bears lie down amid those plants, eat all within reach, sigh and then roll over to reach more without getting to their feet to take a step.
