Does the bathrooms have a 1980's bathroom exhaust fans or do they have windows and no fan or were they replaced? If you still live there can you make a video of what the fan grille looks like in the bathrooms with them running in that house or do you no longer live there where you can't?
+Rondo McBower No, the siding was installed on a slant and not perfectly horizontal. House built in the 80's in Midwest. I guess that was a "thing" at some point.
I've got no love for house sparrows. Foreign birds that aggressively attack our native species. if you ever wonder why you don't see Blue Jays and Cardinals around your house, it's because of them. Humans should continue to rid house sparrows, as a species they need to adapt somewhere else.
1. Youre killing a birds life 2. U couldve got it removed a differnt way like pulling it out and giving it to a wildlife saver. 3. It is illegal to kill or determinate a bird nest unless it is a sparrow or starling.
