Inside the Zoo

There is flight training for the birds of Animal Antics and excitement as the birth of tiger cubs draws closer. Meanwhile, the chimps show off their brain power by playing computer games.

It's busy in the reptile section with snake feeding and the arrival of some geckos. An elderly zebra has worrying dental problems and there's a sad discovery.

The zoo's oldest penguin, Mrs Wolowitz, is injured after a fight. In Koala Territory it's time for the weekly weigh in. The sun bears entertain the crowds while hunting for food.

At Highland Wildlife Park the camel enclosure gets a spring clean and polar bear Walker goes on a diet. Edinburgh Zoo prepares to welcome back giraffes after a 17-year absence.
