Beak
The beak is designed to be as light as possible, but also sturdy. We need to create two beak halves. They are both identical in construction.

There are two coffee stir sticks as the bridge of the nose to allow for an additional coffee stir stick to be inserted. This will be done in a later step.

The popsicle stick for the beak is used for attaching to the axels from the servo. This attachment is done using a loop of wire, which allows for some flexibility.

We will eventually be mounting the beak halves on the front face by threading a coffee stir stick through the side of the nose.

Wings
We need to create two wings for RoboBrrd, one for each side. The only aspect of the construction that will have to be mirrored is the diagonal piece attaching the bottom of the wing to the vertical coffee stir stick.

For the wings, we want to keep them as light as possible, but still give them a good structure for when we are placing felt over them. This is why there is a diagonal piece only on the front side of the wing. There are two coffee stir sticks that attach the wing onto the servo arm on each side. This allows for a better attachment to the servo.

On the other side of the servo arm, we have a counter balance. This uses two pennies in order to move the balance point of the entire wing construction closer to the middle. Theoretically, this will alleviate some stress on the servos.
