Introduction: Plastic Bottle Birdhouse
Second Prize in the
Instructables Green Design Contest
Isn't that the best thing there is? Use your plastic waste for a bird-nursery. After your clothes have been refreshed you step out in nature and you hear the tiny squeaks of little birds housing in your former detergent bottle.
It is easy to make. No special skills needed. And very basic tools.
Still the result looks streamlined like proper designer stuff.
Photo's shown throughout this instructable show a big and a smaller birdhouse, both made in similar ways with minor differences.
The blue rimmed one ismy first built and it is the bigger one. Most instructable steps show the second built one.
It depends op the type of bottles you can find, how the end result will look at the end
Step 1: You Will Need:
strong all purpose scissors
Two plastic detergent bottles
The house one preferably with a more or less square bottom
The roof one almond shaped. See pictures
Step 2: Shaping
Draw the shapes on the bottle with a pencil. The photo's will guide you to the right shape. Make first cuts with a small hacksaw and complete the rest with normal scissors. The all purpose scissor will come in handy on thicker parts.
The first three images show the bottom part of the house. The last three pictures show the roof.
The house: Notice the high facade on the bulky side of the bottle, and a smaller back facade cut out of the handle.
The roof: Ignore the way I removed the handle in two parts. It has no special significance.
Step 3: Splitting the Roof
The under and back side of the roof are cut in two. The cuts ends in a small hole mode with the revolver rod. This prevents the cut from tearing any further. The cutting of the bottom requires the all purpose scissors. The two other holes punched on each side are needed tot attach the roof-part to the house-part.
Step 4: The Entrance
Cut of the top part of the roof bottle, including the cap. Draw a circle on the cap approximately 2,8 -3,2 mm wide for birds like bluetits or tomtits. Punch a hole and cut out with a jigsaw. Cut a fitting big hole in the facade of the house and attach the cap with the other ring. I put my entrance a bit high, may be you will put it a little lower.
Alternately, like i did in the blue rimmed house you could look for an other bottle cap of the right size. Cut top off and squeeze it in a tight hole so it stays without further ado.
If you want to attach a tie-wrap under the porch, now is the time to do so.
Choose a bigger Tie-wrap witch is sturdy enough to carry small birds, and is no use to predators.
Step 5: Decorating the Inside?
I like beds to be made tidy! May be bird specialists would disagree.
I put a pre fabricated nest in. These are for sale in pet stores, but I made this one myself
I made a 2 meter long cord by finger-crochet, coiled it up and sew it together with the same type of rope and a big weaving needle. May be more details in an other instructable.
To secure the nest in the bird house i punched two hole in the bottom of the house end threaded a tie-wrap. A hole in the bottom of the house is a good idea, we don't want to make a birdpool. The overhanging roof will keep the rain out, but you can never be too sure.
Step 6: Back Talk
To attach the roof to the house you will need two tie-wraps at the back of the house. Punch corresponding holes in the back of the roof and the back of the house. If you want you could cut out a piece of remaining plastic to create an more easy way to hang the birdhouse on a wall. The fotos tell all.
Step 7: Room for Sale
Take your birdhouse outside and hang it on a wall. East side is recommended.
Once a year take it down again. Cut the two tie-warps in the back open. Clean the house and hang it back.
I hope you will get many visitors and a family that wants to settle!
