It's time for a quick break from our 12 Days of Christmas celebration for Mailbag Monday; birding questions wait for no holiday! This week, Jon from Quebec asks...
"Four years ago I put up a wooden bird house, but when I took it down this fall to clean it I noticed a lot of bite marks around the hole. Will this affect whether or not birds will use the house again? Each year I've had birds nest in it, and I want them to come back."
The worn condition of the hole won't matter to nesting birds, but it could make the house more tempting to predators that can now reach inside more easily. Furthermore, larger birds such as sparrows or starlings could enter a house with a wider hole, evicting the other birds you've had nest. It is easy to repair bird house holes, and don't forget to review these bird house safety tips at the same time, just to be sure the home you offer is the best one possible!
