The University of Mexico in Mexico City has released a study on birds, nests and cigarette butts.
Apparently, birds that feather their nests with used cigarette butts are able to rid their nests of parasitic mites.
Note to birds: Unsmoked butts do not work nearly as well. They don't contain (sucked up) nicotine.
Tobacco plants are often grown to protect crops by fending off plant-eating insects. They are also grown to help control parasites where poultry is housed.
