big mouth for big bite
starved little nymph cries for a tiny pieces of food to fix its hungry stomach. Probably days after 21 she is out of her home at fledgling stage developing social and anti-social activities and gradually learns to be independent from parents. No matter how well she fly or land or pretend to live independently yet she is dependent on her mother for a piece of bread. During this fledgling stages they develop skills of surviving finding food, avoiding predator and flying well and are pretty risky that they may conveniently caught by their predator or fall to broken wings so are undertaken in supervision of their parents.
Bless ya fly away .. live ya life ;)
