In great Britain during the past few yrs, the birds known as tits have developed the habit of pecking through the cardboard tops of milk bottles delivered in the morning at door steps.Thy open the bottles to get cream.Thy imitate each other & the habit is spreading in other parts of Europe.So through selection of mutants, a new shape of beak might evolve as a result of the changes of habits, provided milk containers & the practices of milk distribution remained the same long enough for birds.
