Zoo Atlanta officials announced today that giant panda Lun Lun, pictured above with cub Mei Lan in 2007, gave birth this morning at 5:39 a.m. in a specially prepared birthing den. Lun Lun was inseminated with sperm from her partner Yang Yang in June after the two failed to mate. The couple’s previous cubs include Mei Lan, born in 2006, and Xi Lan, born in 2008.
