Why this smoking section is actually healthy
I couldn’t resist Googling about nests with cigarettes and found this:
Stuffing cigarette butts into the lining of nests may seem unwholesome. But a team of ecologists says that far from being unnatural, the use of smoked cigarettes by city birds may be an urban variation of an ancient adaptation.
Birds have long been known to line their nests with vegetation rich in compounds that drive away parasites.
After 20 minutes, the team found that devices with unsmoked butts had many more parasites attached to them than devices with smoked butts — which contain more nicotine as the cigarette smoke has passed through them. Indeed, in nests that contained bird eggs, traps with unsmoked butts caught on average more than twice as many parasites.
“It really makes me wonder: might these birds show a preference for cigarette brands high in nicotine? If they did, that might suggest this behaviour has truly evolved as an adaptive response to challenges from parasites,” says Timothy Mousseau, an ecologist at the University of South Carolina in Columbia.
