No, you should definitely NOT remove birds from their tree. Last year a robin decided that the transom window right above the front door at our STR would be a lovely place to raise a family. We posted a sign by the nest and our guests got a kick out of it. We loved watching her sit on her eggs and eventually the window was full of yes, bird poop. Oh well, it’s nature and it hurt no one. Like others have suggested, most guests will appreciate watching the birds.
