Bear seems to be unsupported by anything or at least in a very strange position in frame 1.
No sign of swaying of bird feeder or rope in other frames, especially between frames 2 & 3, bird feeder in almost same position. With a bear moving along on such a thin diameter rope, there would be significant movement of the rope and feeder. Bear is obviously moving a lot, it is in drastically different positions in each frame.
I presume there is bird seed in the feeder. Would a bear risk injury from a fall from such a thin rope, and exert such effort in summer for bird seed when other natural food sources would be available? Obviously there are, the bear does not appear to be thin or emaciated in any way. I could understand a bear trying this in the middle of a harsh, barren winter, but judging by all the foliage, these photos are obviously during warmer/summer months.
