I was exited to put up two bluebird houses, but not so happy when a pair of sparrows enlarged the opening to squeeze in and raise a family this spring. After they were fledged, I scrubbed out the house and added the metal portal protector. It is perfect! Except I have a very sour sparrow who sits on top of her former residence and chirps/chews me out when I walk by!
Perfect size to preserve bluebird house. All ready for new residents!
Was very happy with my shopping experience with nature-niche. We’re delivered quickly and I already have them on my birdhouses. Will be ordering more shortly.
I have used these before at a different address here in Upstate New York & they worked well to keep the pesky starlings and sparrows from taking over... A little early to install them yet—6” of snow here today, but I look forward to getting them on soon...thank you very much!
