After several years of severe drought, water has become a scarce resource. Bird beak shape has determined the of each species.

Which bird beak improves survival

In drought conditions, grain produces smaller crops. Grain-eating birds receive water from grain and survive at a higher rate than other birds.

In drought conditions, conifers produce seeds at a consistent level. Conifer seed-birds receive water from seeds and survive at a higher rate than other birds.

In drought conditions, flowers containing nectar become scarce. Nectar-feeding birds receive water from nectar and survive at a higher rate than the other birds.

In drought conditions, producers die and insects migrate to areas with food. Insect-catching birds receive water from insects and survive at a higher rate than other birds.
