📖 1. Overview
Styan's Bulbul is an endemic bulbul found only in Taiwan, and increasing hybridization with the closely similar Light-vented Bulbul is a major conservation problem.
🦴 2. Anatomy & Morphology
It looks very similar to the Light-vented Bulbul, with the only distinct external difference being almost solely the color of the head feathers.
🔍 3. Ecology & Behavior
Its calls, behavior, and ecological requirements are very similar to those of the Light-vented Bulbul. Over the past 40 years, Light-vented Bulbuls and hybrids have continually moved into its range, putting the pure genetics of Styan's Bulbul at risk of disappearing.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
