My camera was at lease 4'-5' off of the ground as well. The way we knew it was turkeys was there were pictures of the turkey looking right at the camera doing a selfie. How they are able to do it with the camera that high off the ground is anybody's guess. We are covered up with turkeys as well.
Have had my place since 2011. Not until this year has a dang woodpecker pecked at the motion detection lens. My cams are in a kinda half box, attached with zip-ties and mounted on sawhorses. May have to go the t-post route.
Have had a problem with rats knawing the zip-ties in two.
