I've made this tiny bird on a weekend during my summer hollidays in south of France, when the sun was way too hot for me! It took me about 2 days to finish it. It's simple assembly, no glue is requiered, just toothpicks and that will do the trick.
The only tools you need are a sharp knife and toothpicks, a needle or something to drill holes for them.
Step 1: The head
I started by the head, from a curved branch, to have a natural neck. Cut the beack as long as you want, shape the head and the neck. You can drill 2 tiny holes for the eyes, then use a really tiny branch, force it in the hole and cut it, you will have the center white, and around will be brown. I added a "feather" on the top of the head. There was an old branche hole so i used it to fix the feather. Most of the time with weeping willows, you will find the exact same hole in the curve of a branch, take a look ;)
Once your head is done, you can use your knife to cut the wood slightly, to make somekind of feathering.
Then come the body.
Step 2: The body
For the body, you must consider the size of your head+neck first. At the begining, i made a pretty long neck, but i shortened it while i was assambling parts. Take a pretty wide branche, make some rought marks to see what you will have to remove before starting to sculpt more carefully. You can follow the pictures if you don't know how to begin. I added 3 feathers for the tail, 3 holes in the "body tail start" to mount it.
The biggest part await you here, we will build wings! That's not as complicated as it look, once you have your 2 same curved branchs for the base of the wings, it's ok.
