Im pretty sure it's Sithami on the right and Thi on the left. Sithami has tushes which are clearly not visable on the elephant on the left. Also Thi has a lump on her leg.
Lee is correct here. As I have said in another thread the info boards always said Thi was the smallest of the adult cows, this was the case as Sithami was not included as an adult cow when the signs were made.
