Blue tits are bright, inquisitive little birds that have been shown to use aromatic leaves from lavender, mint and curry plants to disinfect their nests. They are also infamous for following milkmen to take sneaky sips from milk bottles by tearing through the foil tops. Cosmopolitan foragers, blue tits are found throughout Britain and as far east as Iran.
Their colourful plumage makes them a cheerful sight on garden feeders, although during spring and summer they mostly feed on invertebrates. The yellowness of a male blue tit's breast is an indication of the number of yellowy-green caterpillars he has eaten, and a brighter breast is more attractive to females.
