I have a wind chime hanging outside with an almost life-size replica of a rt hummingbird serving as the wind catcher. This morning a carolina wren flew into a shrub next to the wind chime. The wren looked around and then surprised me by flying onto the back of the replica and aggressively pecking at the head several times. It flew back to its perch seemingly poised for another go at the replica when it settled down and flew to other shrubs to forage. I wanted to say it was catching some bug on the replica, but the pecks weren't grabbing for food. One never knows what interesting behavior might be observed at any given moment.
