A single bird flies across a calm sky at golden hour. At the 2-second mark, its feathers begin glowing , transforming into flames without changing its shape. It continues flying, now fully made of fire. The camera tracks alongside as sparks fall behind it like embers. Velocity ramp: wings flap in slow motion , flames stretching and flowing like liquid fire. Final moment: the bird explodes into a burst of sparks that reform into multiple smaller birds.
