Blue Tits take aromatic herbs, especially mint into their nests and feed to their young or introduce it to their young. Research has shown that this brings down the incidence of bacterial infection that might affect the fledglings. Blue Tits have been observed actively seeking out mint. Rosemary is another herb they use, but not nearly as frequently.
