Oriole’s Nest

 

Picky, Picky

Scientists have no idea exactly why birds choose certain objects to build their nests. But scientists know that the main reason birds build nests is to keep their babies safe, warm and healthy.

    Baby birds grow faster and are healthier when they are warm. They also learn to fly and leave the nests sooner than birds without warm homes.

What A Yarn (纱)

Yarn is big on an oriole’s shopping list during nest building. Scientists are still trying to work out why so many birds choose white yarn over other colors for nest building.

Scientists think that the white objects remind birds of cotton fluff (绒毛) they find in the wild.

Do It Naturally  

Even though birds can help us recycle some of our junk by using it to build nests, they also need to use lots of natural things. Long grass, dried sticks, spider’s silk and mud are some of the natural ingredients that are good for nests, too.

You can make a collection box of things to leave for birds so they can help themselves. Hang a small plastic box with holes on a tree branch. Fill the box freely with nest building goodies. Hang the box on a tree and watch birds climb on board to pick through the junk to find their treasures.

Warning: Don’t let the birds turn into a tasty treat. Keep your bird station away from places where cats hang out.

For The Birds!

Stop! Don’t throw all that garbage out! Give some to the birds. Look and see how your old junk can help beautify and warm a bird’s new home.
