Generally, if the prey cannot be caught within a chase of 150-300 feet, the lion tires and gives up. However, there have been reports of lions chasing prey for up to 1500 feet. Females usually do the hunting and will often hunt in groups. A second team will then scare the prey, causing it to run into the first team of lions. Not all hunts are successful, but a group has a much better chance of successfully capturing prey than does a lone hunting lion.
Lions are most active at night.
Occasionally they will hunt during the day. Lions may spend up to 20 hours per day just lying around. Lions reach sexual maturity at 2 - 4 years of age, but often continue to grow until they are 5 years old. Cubs generally weigh less than 5 pounds at birth. Births can occur year round, but generally, all of the lions in a pride will give birth at about the same time.
