For a long time there was no systematic observation of the maroon oriole or black-naped oriole in Taiwan either, and there was a dearth of basic information on such topics as in which months they breed, what proportion of their eggs successfully hatch, and how much their populations fluctuate over time.
長期來台灣也缺乏對朱鸝與黃鸝深入觀察，牠們幾月生殖？孵化率如何？族群變動多大？基本資料闕如。
