Experimenters Ebrima and Maheen visit Nina in her workshop and discover how birds make a strong base for their nests. Next, they go to a house built high up in a tree and find out where birds build their nests to make them secure. Finally, they do an experiment that explains how birds keep their eggs cozy and safe.
