Every organism is adapted to its unique environment. This hands-on investigation explores how shape and structure of beaks affects the type of food that birds are able to eat.
Objectives:
Students learn that beak shape affects the kind of seeds a bird can eat.
Over time, birds with a particular beak shape will survive best on a particular type of bird seed.
