This female Mallard sat a few feet to the side of the sleepy group and was preening in a very agitated and frantic manner. As my camera zoomed in closer, I saw the reason. She had a white plastic ring around her neck. It may also have been a rubber band. It wasn’t choking her but it very clearly was a major annoyance. I made a short video of her struggle. Minutes later, with the camera off, she succeeded somehow. She smoothed her feathers and the collar lay on the ground a few feet beside her. Not every bird is so lucky.
