Later, the 10 animals were allowed to extend their territory into a corridor leading to the outside exhibit. The zoo had to let them familiarize themselves with this area and feel safe so that when they finally were let outside, they would know how to get back in. They got some test runs outside last week so they wouldn't be frightened when they are introduced to the public this week and try to run back inside. Or, worse, begin fighting with one another. Sharing the same enclosure, the animals are expected to accept one another, but only up to a point.
Animals breed only within their species.
Last week was the first time in three months that they were allowed outside. On Saturday, at 11 a.m., zoo president Pete Hoskins will cut a ceremonial ribbon. An African culture fest with dancers and musicians will begin. And 10 very rare animals will make their official debut at the Philadelphia Zoo. Philadelphia Newspapers Inc.
