For tools you'll need:
Cone nose pliers
Flat nose pliers
Diagonal cutting pliers
Step 1: Shape the head
For the ease of use I filed a tiny grove into one of the cones of my pliers. You can see this in the second picture. The groove helps show me where to place the wire so I get consistent circles.
Place the center of the wire into the cone pliers and form a small loop. Bend one of the free ends away from the loop as shown in the pictures. Reposition the pliers and bend the other free end away from the loop.
You should now have an overlapping lollypop looking thing. Use the flat pliers to adjust the loop so the free ends are side by side and not overlapping. See the pictures.
Step 2: Form the upper wings
Bend the free ends away from the center, around the cones, and back down the middle.
Adjust as necessary to make the sides even with each other.
Step 3: Form the lower wings
Make sure the pliers are up against the upper wings before you start to bend the wire. Also, see that you wind the loop the same direction; in front on the upper wings.
Step 4: Tail link
File away any sharp edges.
