The starling comes to life.

The same bird, cut into parts: wing, body, legs, eye. Each gesture rotates these parts around their joints instead of swapping two drawings, which gives continuous motion.

Raising the wing

Before, the folded wing disappeared and another wing appeared behind the body: the arm switched sides. Here, the same wing, on the viewer's side, passes in front of the belly and rises, like an arm being raised. It stays in front from start to finish.

  • pivot at the shoulder (96, 100), −185° rotation
  • 100 ms anticipation, 550 ms rise, slight overshoot
  • the wing stays in the foreground, never behind the body
  • the body leans back 3° as a counterweight

Flapping the wings

The wing's points slide from one pose to the other, and the wing tip follows with a lag. A real starling alternates flapping and gliding.

  • 4.2 beats per second, driven by time
  • downstroke 42% of the cycle, upstroke 58%
  • wing tip lag: 12% of the cycle
  • the body rises by 2 units on each downstroke

Walking, foraging, turning around

The starling walks; it does not hop like a sparrow. The feet stay planted while the body moves forward, the leg bends at the heel, and the head follows each step.

  • 5 steps per second, 14-unit steps
  • two-segment legs, heel pointing back
  • foraging: tips 30° forward, twice
  • turning around: a small 320 ms hop

Taking off and landing

The hand-over between the perched bird and the flying bird happens when their silhouettes overlap: wing raised, body leaning 24°. On the way back, it straightens up, squashes a little on the wire, then folds its wing.

  • 350 ms crouch, 250 ms push
  • perched → flying hand-over in one frame, wings up
  • approach: glide with raised wings, then straighten up
  • touchdown: 8% squash, wing folded in 450 ms

Staying alive

Even still, a bird moves a little. These gestures come at random, several seconds apart, so they never become a loop you can spot.

  • breathing: 1% over 3 s
  • blink: 140 ms, every 2 to 6 s
  • shaking: 300 ms, now and then
  • turning around, or just looking over the shoulder

Turning the head

The body stays in profile; only the head turns to look behind. Halfway through the gesture, the beak shows from the front for a split second. Move the pointer over the scene: it looks your way.

  • a separate head: a round skull laid on the silhouette
  • head turn in 130 ms, then held still
  • curious tilt of 8 to 14°, in 250 ms
  • the body and the guidelines do not change
