bison herds

Roaming prairie masses

Bison herds are groups of bison traveling and grazing together.

Historically, vast herds numbering in the millions roamed the North American plains before near-extinction in the 19th century.

The phrase often evokes this image of abundance and loss: The bison herds that once blackened the prairie are gone.

Conservation efforts have restored smaller herds to parks and ranches.
