mothraeve...you are so wrong. It is better to not put up birdhouses then to put poorly mounted houses which put the birds in danger. Houses should be mounted on slick metal poles with predator baffles. Why on earth would you want to put up a house just to have birds move in and then have the eggs or babies eaten????? Do you realize an incuating female is also in danger if a raccoon finds your houses? A raccoon can and will eat an incubating female bird if it raids the nest at the right time. You need to check out sialis.org for information on properly offering nestboxes. Just because you havn't had a problem yet doesn't mean it won't happen. In nature like it a natural cavity if a predator gets a bird, well that is nature. If it happens in a poorly mounted nestbox, that isn't nature, it is the fault of the person putting up the nestboxes. Just because lots of people put them up improperly and endanger the birds by doing so doesn't mean that you should give advice that it is ok to do this. It isn't ok to put birdhouses on trees of fences! You should take your boxes down if that is the way you think. Plus unless you actually monitor your nestboxes you would have no way of knowing if the nesting actually succeeded or not.

Carolina Wrens are not destructive like House Wrens. CAWR are cheerful and welcome guests at my home any time! CAWR will nest in many odd places; a nestbox or shelf, a flowerpot, a fallen tree stump, an old boot, a clay pot, a bush, a motorcycle helmet, a hole in a stone wall or mudbank, nooks & crannies, mailboxes, an old hat, a coat pocket, ... surely I've missed a few? Our local garden center had a decorative nestbox on a shelf over the cash register. A pair of Carolina Wrens popped in and out as needed to feed their young surprising many customers, including me!

I replaced an old wren nesting box with a Black Capped Chickadee nesting box and while I was at it I thought I would also install a nature/bird cam. Hopefully its not to late in the season to attract a nesting pair. Here is a link that might be useful: Installing nesting box and bird cam

Hi Michelle, I responded on the other thread that you posted on. If the wrens have already found the nestbox it may be too late to do anything about it this year. You need to make a wren guard and use it before the wrens find the opening to your bluebird nestbox. Go to www.sialis.org to learn how to make and use a wren guard. For this year I'm afraid I would tell you to give up and either take down the nestboxes or open the doors so that they can't be used. I'm sorry you are having a problem but you can try again next year.
