Panda Meng Meng expects twins in Berlin

The Berlin Zoo has announced that its 11-year-old female giant panda Meng Meng is pregnant again with twins and, if everything goes well, could give birth by the end of the month.

The announcement was made on Monday after zoo authorities conducted an ultrasound examination over the weekend that showed the developing fetuses. Giant panda experts from China arrived in Berlin on Sunday to assist with preparations for the ultrasound.

Meng Meng was artificially inseminated in March. According to the zoo, female giant pandas are only fertile for approximately 72 hours each year.
