Is 栖 pronounced xi or qi as in 两栖？ I checked several dictionaries it's [liǎng qī].
But it's pronounced xi in this  video.
栖 is the simplified character of 棲
棲 has two different pinyin

棲 /qi1/



(of birds) perch; roost




dwell; stay; reside; settle


~

棲 /xi1/


[adj] restless; fidgety

兩棲  /liang3 qi1 / amphibious; dual-talented; able to work in two different lines
The video use  /xi1/ instead of /qi1/, which doesn't match the dictionary. And base on the context, the dictionary is the correct one here
