I've had a few gals ask about how I made the aviary so I thought i'd share here. I had an old armoire or oversized tv cabinet that we weren't using. One day it clicked - I could re-purpose it into something i'd been wanting - a bigger house for my finches!
I was lucky in how the armoire had been built... it had a vertical support post in each corner. Each side board was attached to these supports, so when they were removed, I had a top, bottom and corner supports.
I measured and sketched my armoire skeleton - planning doors and hatches. I also planned for a drawer. With a drawer spanning the entire bottom area, I could more easily clean out the bottom of the habitat.
The doors and hatches were each framed with 1x1s mitered at the corners. Mine aren't as well done as they look from these photos - but their unevenness adds to the charm of it. ;-)
Once everything was built and in place, I painted. Use a non-toxic paint that won't harm the birds. I think it got 2 coats of paint.
Before I put the meshwork up, I added the large branch. I knew once the walls and doors were on, that I wouldn't be able to get it inside. I was lucky and a neighbor had just cut down their eucalyptus tree, so I picked thru their debris pile and found this gem. I bolted it to a support beam that happened to run across the "ceiling" of the armoire. This could also be hung from a large hook or hoop.
Next came the mesh. I used 1/4" mesh for the finches. For Canaries, you could probably go a little bigger, but 1/4" would be best. (I don't suggest this for larger chewing birds - parrots, macaws, etc - as they may chew at the wood?)
I used a handheld staple gun to put all the mesh into place (adhering from the inside of the aviary.) You could finish off the edges of the mesh with small 1/4-round molding if you wanted.
okay - once the walls and doors were "meshed" I started hinging the doors into place. Then added eyehook/hook closures to keep them closed.
I added some toys and accessories and tada! A great home for my winged friends.
