falcon
隼 centers on a specific bird of prey: the falcon, known for its speed and hunting ability.
隼 is a phono-semantic compound combining 隹 (bird) with 十, which may have originally represented a phonetic element or a stylized feature of the falcon. The exact historical development is uncertain.
隹 is a bird, and 十 looks like a cross-shaped perch. Picture a falcon perched on a cross-shaped stand, ready to hunt.
For シュン, imagine a falcon swooping down so fast it makes a 'shoon' sound: shoon -> シュン.
