Buffalo Chase, Bull Protecting a Cow and Calf

“During the season of the year whilst the calves are young, the male seems to stroll about by the side of the dam, as if for the purpose of protecting the young, at which time it is exceedingly hazardous to attack them, as they are sure to turn upon their pursuers, who have often to fly to each others assistance.” George Catlin sketched this scene on the Upper Missouri in 1832.
