"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.

However, individual blue tits are quite picky about which plants they use, and it is not clear how they pass their knowledge on to other birds."
