Hi. We have a single Blue Tit using the nesting box over the last month or so and can see that this is fairly common behaviour. As it has a camera feed, we can also see the mess it’s leaving. Should we clean this out occasionally or leave it for the “birds” to deal with when they nest properly in Spring.
Hi, I notice that this query has come up before (Blue tit bird box cleaning) and Catlady suggested cleaning it out as "they will soon come back to roost in them on a cold wet windy night", so perhaps it would be okay if you can get it back in place asap. Whatever you end up doing, please report back so we can learn from what you tried.
