I love this birdhouse and chickadees and wrens have both built nests (but unfortunately not stayed thus far). I do agree with other reviewers in that it is somewhat fragile and I would definitely advise against leaving out during the winter as I did. I actually had a mouse build a nest in the top hole, using the flap from the back as material! I now have to replace that in order to close it up. The top anchor which holds the loop has rusted through completely and no longer closes, so it is a matter of time before it is on the ground. I will also need to replace that or just replace the house altogether. I got approximately two years out of the purchase and for the price I am okay with that. Because of the above, I would say maybe sheltered use, such as attached to a tree or post might be best.
