Feather plucking, wing feather biting, and excessive noise are all common signs of being bored with the environment. A Jenday conure needs a new toy or exercise to keep it occupied. Wing feather biting is often caused by too much close contact with other pets in the home. Provide more space for your bird to roam around. It should be easier to control the problem if you purchase some behavior-changing toys that can be placed near the perch or cage. The Jenday conure also has extremely sensitive hearing and will respond to any sudden noises like the TV on, sudden noises like thunderstorms, or sudden noises like an alarm clock going off.
