Now do this put-the-text-back-together activity.
This is the text (if you need help).
Scientists know why birds' eggs are different shapes. People once said male chicks came from rounder eggs, but that was wrong. Scientists say the shape makes birds fly better. A professor said birds have changed to lay eggs that have different shapes - from a round owl's egg to a pointy sandpiper egg.
The scientists looked at 50,000 eggs from 1,400 different bird species. They looked at the shape, length and height of the eggs. Birds with the most-oval-shaped eggs were the best fliers. Hummingbirds have the most-oval-shaped eggs; owls have the roundest eggs; and sea birds have the pointiest eggs.
