Building a birdhouse nesting area will allow birds to remain safe while you recycle products to help the environment. Birds look for places to nest, especially when they are limited by the amount of trees and natural habitats around them. You can make your own nesting area for birds with a plastic 2-liter bottle. Once you build a birdhouse for the birds, you can create several more nests to hang outside on trees or poles to attract different birds to your yard.
Clean the 2-liter bottle out with warm water and a mild soap. Pour the soap and warm water into the bottle, replace the lid and shake it to remove any sticky residue. Remove the labels from the bottle, and allow the bottle to air dry.
Place the 2-liter bottle horizontally on a flat surface. Hold it securely with one hand, and use your other hand to make a hole in the middle of the side of the bottle with a sharp knife.
Draw a circle with a permanent marker around the small hole. The hole size will depend on the type of bird that you wish to live in the bird house nest. Cut the hole with a pair of sharp scissors.
Lay out newspapers on a flat surface and paint the bottle with a spray paint designed for plastics. Painting the birdhouse will keep out light for the birds. Allow the bottle to dry.
Wrap craft wire around the neck of your two liter. Wrap it around 2 to 3 times tightly to ensure that the bottle remains secured to the wire. Make a loop in the wire atop the neck, and tie it securely.
Place bird nest supplies around the birdhouse nest so that the bird will be able to build their nest. Leave behind small tree stems, dryer lint and dried grass for best results.
