Ours would be very interested in investigating that arrangement, I think. A bit destructive in their interest sometimes!
It does remind me of a time I lived in an upstairs apartment with a long deck that had a wooden rail. For a winter decoration out there, I wired branches of Yaupon, with red berries, all along it, and to my delight this attracted mockingbirds who sat on the rail and feasted on the berries.
