Boars may occasionally prey on small vertebrates like newborn deer fawns, leporids and galliform chicks. It is the largest of only three leporids known from South America. "Aztlanolagus" may be distinguished from all other known leporids as follows. This riverine region lacks ground squirrels and has low numbers of leporids. In areas where leporids are scarce, this group of rodents seems to become more prominent. Hares and jackrabbits are leporids belonging to the genus Lepus. Wild leporids comprise a small portion of global rabbit-meat consumption. Leporids are typically polygynandrous, and have highly developed social systems. Leporids are small to moderately sized mammals, adapted for rapid movement.
