📖 1. Overview

🌐 Wikipedia Summary ExtractThe peregrine falcon, sometimes referred to simply as the peregrine, is a bird of prey (raptor) in the family Falconidae known for its speed. A large, crow-sized falcon, it has a blue-grey back, barred white underparts and a black head. As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males. Historically, the bird has also been known as the "black-cheeked falcon" in Australia and the "duck hawk" in North America.
🦴 2. Anatomy & Morphology
Along with its streamlined body (0.45 m body length, 1.1 m wingspan), the cone-shaped air-slowing baffle tubercles inside its nostrils that prevent lung rupture during ultra-high-speed flight were directly applied to jet engine design.
🔍 3. Ecology & Behavior
It is an iconic flagship species in global environmental conservation history, having recovered its population after the ban on DDT pesticides.
🇰🇷 4. Connection to Korea
It is the star of traditional Korean falconry (listed as UNESCO Intangible Cultural Heritage of Humanity) and is designated as Natural Monument (Korea) No. 323-7.
