It is calculated by adding up the weights of all of the individuals. People are bipeds, so are birds. BIRD Birds have feathers and wings.
Many birds eat butterflies and moths.
They may be the descendants of theropod dinosaurs. These enormous butterflies usually live high in the tops of trees in rain forests. Adults sip flower nectar. Many birdwings are in danger of extinction. The tiny round eggs are yellow to cream-colored.
