A giant panda spends much of its day resting, feeding, and seeking food. Unlike other bears from cool climate, giant pandas do not hibernate or sleep during winter. Until now, scientists thought that giant pandas are solitary animals. They spent most of their lives alone with males and females meeting only during the breeding season. Recent studies have found differently that small groups of pandas live in a large territory and males and females sometimes meet outside the breeding season. Therefore, the secret lives of giant pandas should be learned and a new discovery can help scientists save their lives.
