Step 1.
Make a bird base, lay it flat on the table, so that the two long points separated by a slit are oriented at 6 o'clock.
Step 2.
Place the left thumb between the two lower points, along the vertical slit.
Slide the left index finger inside the lower left point, at the point where the vertical axis of symmetry becomes a slit.
additional information
- For this, open the point and lay it almost flat.
- The left thumb is against a mountain fold, and the left index finger against the corresponding valley fold.
Step 3.
With the thumb, lift the point in order to invert it inside itself.
additional information
- The mountain fold against the thumb becomes a valley fold.
- the valley fold against the index becomes a mountain fold.
- the long left point is oriented at 10 o'clock.
- the bisector of this long left point must align with the left point of the front flap.
Step 4.
Turn the model over from right to left, then redo the manipulations described in steps 2 and 3.
additional information
- The large front flap has 5 points:
- An upper point, a right point, a lower right point, a lower left point, and a left point.
- The right point of the front flap is located at the bisector of the long right point of the shape.
- The left point of the front flap is located at the bisector of the long left point of the shape.
- You can fold everything along the vertical axis to check that the model is well symmetrical.
Step 5.
Make a vertical valley fold, folding from right to left, the right tip of the front flap, against the fold.
additional information
- the valley fold starts at the level of the lower right tip of the front flap.
- the valley fold ends at the intersection point between the right edge of the front flap and the left edge of the long right tip of the shape.
- crease well and leave it folded.
Step 6.
Make a vertical valley fold, folding from left to right, the left tip of the front flap, against the fold.
additional information
- the valley fold starts at the level of the lower left tip of the front flap.
- the valley fold stops at the point of intersection between the left edge of the front flap and the right edge of the long left point of the shape.
- crease well and leave it folded.
Step 7.
Turn the model over from right to left, then repeat the manipulations described in steps 5 and 6.
Step 8.
Open the long left point, then bring it back to the position it had when the model was in the bird base.
Step 9.
Open the long right point, then bring it back to the position it had when the model was in the bird base.
additional information
- compared to the initial bird base, the front right, back right, front left, and back left points have been transformed into vertical folds.
Step 10.
Transform the right and left vertical valley folds of the front flap into mountain folds.
Step 11.
Turn the model over from right to left, then repeat the manipulations described in step 10.
Step 12.
Transform the small right and left points of the front flap into sunk folds.
Step 13.
Turn the model over from right to left, then repeat the manipulations described in step 12.
Step 14.
Flip the long lower right point again, using the existing folds.
Step 15.
Flip the long lower left point again, using the existing folds.
additional information
- The long right point ends up oriented at 2 o'clock, and the long left point ends up oriented at 10 o'clock.
Step 16.
Fully open the long straight point to give it the shape of a double-layered kite, with a slit along its long diagonal.
Step 17.
Fold down the large sides of the kite along the slit marking the kite's long diagonal.
Step 18.
Fold the top part of the kite over its bottom part to transform this kite into a long tapered tip.
Step 19.
Turn the model over from right to left, then redo the manipulations described in steps 16, 17, and 18.
Step 20.
Lower the large front flap from top to bottom.
Step 21.
Turn the model over from right to left, then redo the manipulation described in step 20.
additional information
- The model includes:
- a long tapered tip on the left, oriented at 10 o'clock.
- a closed upper tip, pointing at 12 o'clock.
- a long straight tapered tip, pointing at 2 o'clock.
- a large front lower double-thickness triangular flap, with a slit on the underside.
- a large rear lower double-thickness triangular flap, with a slit on the top.
- the free tip of the large triangular flaps is pointing at 6 o'clock.
- the right and left parts of the fold are symmetrical.
Step 22.
Fold the right part of the fold over the left part, using the vertical axis of symmetry.
Step 23.
Rotate the model a quarter turn counterclockwise, then turn the model over from right to left.
additional information
- the upper edge of the fold is a horizontal hinge edge, connecting the front flap to the rear flap.
- the right part is a short point oriented at 3 o'clock, (it will become the tail).
- the left part is a longer point oriented at 9 o'clock, (it will become the head).
- the lower part is made up of two long tapered tips oriented at 5 o'clock, which overlap. (They will become the legs).
Step 24.
Lower the long left point by an inside reverse fold, to bring it parallel to the long tapered lower points.
Step 25.
Lift this same point by a second inside reverse fold, to orient it at 12 o'clock.
additional information
- This point oriented at 12 o'clock is actually made up of two identical points nested within each other.
Step 26.
Make an inside reverse fold of about 1 centimeter at the tip of the inner point to form the beak.
Step 27.
Make an outside reverse fold of slightly shorter length at the tip of the outer point to form the crest.
Step 28.
Lower, then raise the right point to shape the tail.
Step 29.
Open the ends of the legs so that the bird can balance.
