Hello!
I would like to clarify some information about the Columbus Zoos elephant program. I hope this will help clear up any information about the zoos breeding program.
I would like to explain why the Columbus Zoo has not had any offspring from Rudy and Sunny when they are 20 and 13. The main reason behind this is because the zoo wanted Rudy and Sunny to experience the birth of a calf and how an experienced mother would care for it to teach them about how to be a mother. When Phoebe became pregnant with Ellie, the zoo planed to breed Rudy and Sunny shortly after the birth so they would know how to raise their own calves but unfortunately Ellie passed away so they decided to wait for them to get pregnant until they could see Phoebe taking care of a calf. Once the zoo found out that Phoebe was pregnant again they started to work to get Beco to breed with Rudy and Sunny. Beco breed with both the girls before he passed away but it has not been announced if they are pregnant yet. AI also might have been used on the girls as I know they were talking about it but I am unsure whether they made any attempts. I currently suspect that Sunny might be pregnant as she has been noticeably been getting rounder over the past months. So far though I have not seen much growth of her mammary glands but she might not be to that point of her pregnancy, if she is pregnant, yet. Here is a picture of her from July 9 and you can clearly notice how round she is (Sunny is on the right)
Sunny is a rounder elephant but unless she is on a brand new diet to gain wait, I believe she might be pregnant. Meanwhile I have not seen much weight gained on Rudy leading me to believe she is not pregnant. If anybody as any questions about the Columbus Zoo’s elephant program please feel free to ask me!
