At the beginning of the 20th century, blue tits learned to remove the foil from the bottle of milk and collect the cream located on the top. When a practice of milk delivery became obsolete, blue tits returned to their original food sources.
Diet based on yellow-green caterpillars increases the intensity of the yellow color of the male's breast and increases his chances to find the mating partner (yellow breasts signalize that male can provide adequate amount of food for the offspring).
