What do birds use their beaks for and why would there be differences between species
Ira Lisetskai [31]

Answer:

The main use of a beak is for feeding. Since beaks are mainly used for feeding, the variation in beak shape and size mostly has to do with the food that each species prefers. Some beaks are made for digging seeds out of shells while others are designed to dig deep into the ground to pull out prey items.
