With only 100 Vultures remaining in the wild in Israel, scientists don’t want to take any chances with the precious eggs breaking or being preyed upon. So when a pair of wild Vultures in an Israeli nature reserve laid an egg, scientists collected the egg and brought it to the Jerusalem Zoo, where it was placed in the safety of an incubator.
Meanwhile, at the Ramat Gan Safari Park, Vultures Donky and Kosta were sitting on a dummy egg, because the two eggs that they had laid earlier were removed from the nest. Once the wild-collected egg began to hatch in the incubator at the Jerusalem Zoo, it was rushed to Ramat Gan Safari Park.
Vultures are unable to tell if a chick is theirs or not, so a brave zoo keeper entered Donky and Kosta’s enclosure, climbed up to the nesting shelf, removed the dummy egg, and replaced it with a newly hatched chick, which was still in its shell. Not an easy task when you have two protective Vultures nearby!
Father Kosta immediately returned to the nest to make sure the egg was still there after the "intruder's" visit. To his surprise, he found that a tiny chick waiting for him in the nest, begging for food. Kosta did not think twice and rushed to feed the chick
Kosta and Donkey have successfully fostered several chicks over the years.
By the age of 6 months, the chick will be taken to a nature reserve, where it will spend three years with other young Vultures until it is old enough to be released to the wild and join the wild population.
