TORONTO, Oct 13 (Reuters) - A giant panda at the Toronto Zoo
gave birth to twin cubs on Tuesday, the first baby pandas born
in Canada since the zoo accepted two pandas on loan from China
in 2013.
Er Shun gave birth to the cubs 13 minutes apart shortly
after 3 a.m. ET, the zoo said in a statement. The cubs weighed
188 grams and 115 grams at birth and their sex has not yet been
determined.
"Er Shun is demonstrating excellent maternal instincts and
began cleaning and cradling the first cub soon after its birth,"
the zoo said in the statement.
"While this is wonderful news, the tiny cubs are very
vulnerable at this size, so the next several hours and days will
be critical to their survival."
The cubs, about the size of a guinea pig, were conceived
through artificial insemination using sperm from her Toronto Zoo
partner Da Mao as well as the frozen sperm from two giant pandas
living in China. The paternity of the cubs may not be known for
several months, the zoo said.
The cubs, born pink with sparse white hair, will be cared
for in a maternity area of the giant panda house for several
months, and "twin-swapped" between an incubator and their mother
so they have time to bond with Er Shun.
Er Shun and Da Mao are on loan from China for 10 years as
part of a long-term breeding program. They will remain at the
Toronto zoo until 2018 and then relocate to the Calgary Zoo for
five years.
