With the arrival of spring comes some exciting news from China: panda Su Lin has bred! Seven-year-old Su Lin, who was born at the San Diego Zoo in August 2005, bred with male Yuan Yuan several times at Bi Feng Xia, and all appeared to go perfectly. We are waiting to hear whether she breeds with any more males over the next few days, and we have high hopes that this will be a successful pregnancy for Su Lin. Her first cub was born in July 2011 (see Su Lin Gives Birth!). We were also happy to receive some recent photos of Su Lin, and she looks happy and healthy and is as beautiful as ever!
We’ve also received a recent photo of 13-year-old Hua Mei’s latest cub. As you may recall, Hua Mei was born here in August 1999 and has given birth to nine cubs over the years since she moved to China in 2004. It is such a pleasure to see Bai Yun’s newest grandcub, a girl, born in August 2012! We’ve also learned that Hua Mei and Su Lin have been neighbors at Bi Feng Xia.
Mei Sheng has also had opportunities to mate this year, but thus far he’s shown that he still has some learning to do. Even though Mei Sheng, born here in August 2003 and now nine years old, is a fully adult panda, male pandas tend to mature later than females, so there is still plenty of time left for him to become a more adept breeder.
The breeding season has been in full swing for pandas at Bi Feng Xia for about a month now, and panda females may continue to come into estrus through June. While each female only has a single estrus, and just a few days of interest in breeding, males will have opportunities to breed throughout the entire spring. We will keep you posted, and all of our fingers are crossed in hopes for a successful year there.
