That means no bird-patterned wallpaper, crockery or artwork either - as even images of birds can spell doom. Keep bad luck and death at bay by keeping birds out in all their forms. If a wild bird somehow manages to enter your home - through a door, window or chimney – you'll suffer a bout of bad luck, and some legends say it foreshadows the death of someone in the home. Maybe it's time to invest in a new Sunday suit. Getting bombed by the droppings of a rook is penance for not wearing new clothes on Easter. While most superstitions about bird droppings are positive, some older British tales warn that if the droppings come from a rook, it's actually a punishment rather than a blessing. Sailors believe that bird droppings should never be removed from the vessel until after the next rainstorm, which will probably take care of most of the cleanup anyway. Even better, you don't have to let the mess (which some people use as skin treatment!) linger you can safely clean the droppings off without wiping away your newfound luck – unless, of course, you're on a ship. At first glance, this might sound like the start of a really bad day, but superstitious types believe it's actually a sign of luck. You're strolling around outside on your lunch break when, all of a sudden, a bird lets loose above you, depositing a messy smear of droppings on your head.
