An extreme example is the "it's called a zygyzgy of ptarmigans"-type alternative words for flocks of specific birds in English, which are basically made up and unused.
(Well, maybe during the North American skiing season more than in late May.)
Arguably the existence of niche words could even mean less, as in the flock words example, words that have more or less been invented as pure word games.
A climbing partner and I counted over 60 words for snow in (our idiosyncratic) English.
So, I guess there Inuit, English speakers and mountaineers as three different populations.
