Yes, signs are encouraging considering he was deemed able to rejoin his family. The fact Zayana gave birth outside is unusual. Obviously the cubs are safer in a nest box; but despite the risks the outside exhibit presents, it’s important to give Zayana the choice and that’s obviously where she feels most comfortable. She gave birth to the previous litter outside as well.
It's really congratulations to Auckland for being able to construct an exhibit that has enabled her to be comfortable on exhibit so much that she's given birth there! Privacy and safety are both very important and that's why most big cats prefer to give birth in dens. Obviously Zayana feels she has enough privacy outdoors and they're safe enough for her cubs which is a really positive sign of Auckland's success with their new habitats.It did seem unusual that Zayana chose to give birth outside, as in general most of the zoo animals seem to prefer indoor births. The only other instance I've heard about of an outdoor birth at Auckland Zoo was a nyala calf last year - the calf was apparently born in front of astonished visitors during the Easter holidays.
