There is overlap with Slovak-speaking Gorals in the south. The Southwest Side is home to the largest concentration of Gorals (Carpathian highlanders) outside Europe. Serows are smaller than takins but significantly larger than gorals. Serows have shorter and coarser wool than gorals. A significant portion of the heritage of Gorals comes from the assimilated Vlachs. American anthropologists termed the Gorals "Black Russians", while noting that the western Gorals spoke Polish. Poaching of wild gorals is increasing; they are poached for their fur, meat, and horns. Very similar versions can be found at the Gorals in Slovakia and in Czech Republic. Among the speakers of Polish in Passaic are many Gorals. Serows, unlike gorals, make use of their preorbital glands in scent marking. The gorals are four species in the genus Nemorhaedus or Naemorhedus. Red gorals typically inhabit a home range of around 40 hectares. In 1982, 18 gorals died in captivity in the Indian Zoo. Both serows and gorals live in rainy mountainous regions and are excellent climbers. Local Gorals formed (as indigenous people) a majority in the past.
