When God created the bird kinds on day five of creation week, he gave them the know-how they’d need to care for their young in a fallen world. For many bird species, this includes building nests to protect their eggs and hatchlings.

• Orioles spend days weaving and tying plant fibers to create an intricate hanging nest.
• Not all birds build nests in trees. Some birds nest right on the ground.
• Bald eagles hold the record for largest nest. The nest was over 9 feet wide and 20 feet deep. That’s deeper than a two-story house is tall.
• Female birds usually do most of the nest building.
• It’s a myth that a bird will abandon its nest if a human touches the nest.
• Hummingbirds build the smallest nests—as tiny as a thimble.
• Barn swallows make up to 1,200 trips to collect enough mud to build their nests.
• The colors of bird eggs—from robin’s egg blue to the sparrow’s brown speckles—depends on the mother bird’s diet.
• Many birds use materials such as spider webs, mud, or saliva to help hold their nests together.
• The potoo bird lays its egg on the top of a tree stump.
