You might try contacting Campark at the email addy I gave you. They might have replacement parts although II sorta doubt it since the cams are so cheap anyway. Another thing I noticed is the lens on these cams protrudes from the camera frame unlike most trail cams that have the lens recessed. With a lens that protrudes like that, it would tend to catch rays from the sun, have reflections from its surroundings and thus be more enticing for a critter to investigate. I've used other trail cams with recessed lenses and have never had a bird problem with the lens or camera. If you keep getting your camera lenses messed up by birds, you may want to consider a different brand of game camera with a recessed lens design.
