"Yang Yang" is the first captive panda mother to have raised twins without human help. That she's not a raven, but a super-mother confirms a research paper published Thursday in the "PLOS ONE Journal".
Martina Heiderer, Tiergarten's badistant scientist, examined how "Yang Yang" had managed the breeding. "Thanks to the shots in the launch box, I was able to badyze the behavior of" Yang Yang "and his twins" Fu Feng "and" Fu Ban "during the first four months of my life and examine how they managed twin breeding in time, "said Heiderer,
Livestock data were compared with those of "Fu Long" and "Fu Hu". The results are incredible. Heiderer: "Yang Yang" spent as much time with each of the twins as it did on his juveniles, cleaning two young animals took twice as long, and badfeeding took longer as they did not always drink at the same time, did not save the extra time required on their little ones, but sacrificed their own rest and slept less. "
In order to badyze the time budget, Heiderer watched the video minute by minute and indicated if "Yang Yang" was sleeping, badfeeding or cleaning their babies. "At one point, I had the feeling of seeing only black and white."
