I purchased this house and received it very quickly! So well made, both side doors are easy to open and access, and I was pleasantly surprised when one of the side doors opens to reveal a clear window for easy viewing of the nest and birds!!! The Noel guard was very easy to install and enclosed was an extra piece of wire flooring to set inside the house to prevent blow fly larvae. My husband installed it onto a 4x4 post facing NE in an open area with a view of open grass. It was installed this past Saturday and two days later we have new tenants, they have been in and out all morning!!! I’m anxious and very hopeful that the Noel guard will be effective at keeping out predators. I’m elated with joy and I will definitely be ordering again from Duncraft! Thank you!!!
