It has been shown that women have more sensitive noses than men. It would make more sense that they have to avoid spoiled food when feeding children and bacterially contaminated areas. Apparently some birds also use their noses to minimize bacterial contamination.
Blue tits use medicinal plants to disinfect their nests, scientists have discovered.
The birds line their nests with aromatic plants such as mint or lavender, which kill bacteria.
That creates a more sterile environment for chicks, which in turn grow faster and have a better chance of survival.
They found that aromatic plants, including lavender (Lavandula stoechas), apple mint (Mentha suaveolens), the curry plant (Helichrysum itlaicum) and Achillea ligustica significantly change the composition of bacterial communities living on blue tit nestlings.
