We've had 2 wooden birdboxes near our fence for the past few years. We've had sparrows nesting in them. I noticed this year that no one is interested in them. I dont know why, perhaps we are supposed to clean them out? We have never cleaned them out..could there be something bad or hazardous inside and the birds know they shouldn't nest there?
Thanks !
