Entity of the month
Scientists have long known that birds inhabiting urban environments often use items of human litter to build their nests. In one instance, a species appears to have harnessed the toxic chemicals in discarded cigarette butts in an effort to ward off ectoparasites, such as ticks, from their nests. A team of researchers led by Constantino Macías Garcia at the National Autonomous University of Mexico noticed a peculiar behaviour in house finches (Carpodacus mexicanus) inhabiting the main campus of the university in Mexico City; they were lining their nests with toxic cigarette butts.
