Blue Jays in my area are the problem. They have the ugliest call of any bird eva!.

Maybe some background noise would help. I love listening to sounds of nature (obviously not a choice for you ), or classical. White noise machines or a fan running can help too.

Shift work can be painful, g/l dude.
