The panda harvest is fruitful this year.

Almost two months after the National Zoo’s Mei Xiang gave birth to twins, the Toronto Zoo’s giant panda Er Shun has welcomed two bouncing bundles of black and white (well, pink for now) into the world, reports The Associated Press.

On Tuesday morning, Er Shun, who is on loan to the Canadian zoo from China, gave birth to the two cub weighing 115 grams and just under 188 grams. These babies are the first panda cubs born in Canada.

The zoo’s staff says the mom and her cubs “appear to be doing well” and that “Er Shun is demonstrating excellent maternal instincts.”

The next several days will be critical for the cubs. The National Zoo lost one of their twin cubs just a few days after is was born, which is another reason the Toronto Zoo’s staff is being especially cautious.

The zoo cannot confirm the sex of the newborns or which panda fathered the pair. It may be several months before the sex and paternity can be determined.
