Edinburgh Zoo pandas: Celebrate one year in Scotland

It is one year since two giant pandas arrived at Edinburgh Zoo from China.

The zoo says it has learned a lot about Tian Tian (meaning Sweetie) and Yang Guang (Sunshine) in the past year including how they are affected by natural light levels in Scotland.

It has high hopes they will mate in 2013. The zoo also says the pandas have helped get its finances back on an even keel.

The BBC's Scotland correspondent James Cook reports.
