Did you know that it's illegal to collect songbird nests? True. I'm not sure why this rule came into being because most often, migratory birds won't re-use an old nest (could it be they know about parasites overwintering in them?)
So to satisfy that rule, I developed my own faux birds nest, which is just as appealing, and doesn't have any bugs in it as an added bonus. It also looks very realistic to humans, although a bird probably could tell the difference.
Here's how I started; with a piece of wire about 12-16" long, I twist
it into a circle. Roughly speaking. Then I took some flexible twigs,
in this case Sheperdia canadensis, otherwise known as Buffaloberry or
soopolallie, and wound those around the wire.
The point here is to make a kind of bowl shape, and neatness doesn't count. Just the general shape is fine.
Then I put some spanish moss from the dollar store in a pile in the middle and hollowed out the center, just like a real nest. I have some tiny wrens eggs (also from the dollar store), which are turned wood pieces. Of course, they are hidden away and unfindable, so I went with plan B:
Oval beads with some strips of newspaper to be papier mache - leave them rustic!
Smudged with some acrylic craft paint, they resemble real songbird eggs.
Display your tiny nest under a glass cloche with a rustic twig - I always wanted to use this little blown glass cloche for something!
