I love the Catbirds and wish we had them year round but they only visit here during winter and head back north in mid to late April. I found a dead Catbird on the sidewalk last week ... it had apparently slammed itself into the sliding glass doors of our back bedroom.
Even though the tint keeps the stifling afternoon sun from heating up the room I hate it because of the issues of birds flying into the glass. I need to try to find some decals that will work outside in the weather!
