There are reindeer in North America, but we call them "caribou"

The genetic makeup of reindeer and caribou is the same. The two main populations are in sub-arctic regions of Scandinavia and North America; these two populations have been separated for centuries,  and couldn't  interbreed. As a result, the two populations have evolved a little differently - the caribou being slightly larger than the Scandinavian reindeer

One member of the species has a glowing. red nose but scientists haven't located it yet.
