Battle of the Beaks
This practical activity explores beak adaptations in bird populations and looks at the way in which variation in beak shape is related to the available food sources within an environment.
Students simulate bird feeding by using a ‘beak’ to collect food and place it into a stomach. There are four different beak shapes and a range of different food types to choose from. Discussion points are provided to encourage evaluation of the scientific method, together with extension ideas. The activity can also be used to illustrate generalist versus specialist feeding strategies.
