Detlef Oh ya I know you were innocently joking. I'm sure that's a word that doesn't come up in conversation very often for most people.
Here in Canada over the last 30+ years there's been an effort made to use the names these different communities choose not ones that were given to them by the settlers who weren't looking out for their best interests most of the time.
In Canada they like us to use the term Indigenous instead of Indian. Indian is like Eskimo we don't use it here anymore because these communities don't like it. Native is also a term you used to hear more years ago and is still ok, but less formal.
Here the different Indigenous communities are called Bands not Tribes. So Native Band is normal. We don't have reservations that was a USA thing. Here it's just referred to as Native Land or Band Land. Native land is spread out all over the place. Usually in and around old historic Native communities.
We also have a different history here than the one south of the boarder. Following the 1876 Battle of the Little Bighorn, Sitting Bull led roughly 5,000 Lakota Sioux into the province of Saskatchewan, Canada to escape U.S. Army retaliation.
In the USA the old terms are still used because why would they change?
