See inside an endangered California condor egg just before it hatches

A scan of a California condor (Gymnogyps californianus) egg has revealed a hardly ever seen embryonic world. The chick is the 250th condor hatched at a facility serving to to convey again the threatened birds from the brink of extinction.

Like every condor egg laid within the San Diego Zoo Wildlife Alliance’s breeding program, this one was carefully monitored by veterinary workers to make sure it was rising usually. As a part of these common check-ups, specialists “candle” the growing eggs by putting a lightweight towards the shell to examine the place of the chick inside.

All eggs have an air pocket inside, however this one was in an uncommon place, which steered the chick was contorted. Such a place can hurt its probability of hatching efficiently. The crew determined to do a computed tomography (CT) scan to peek contained in the shell – one thing they’ve needed to do for earlier eggs, too.

“We are able to see the skeleton and air pockets within the egg,” says Nora Willis on the San Diego Zoo Wildlife Alliance. “I’m nonetheless blown away by it.”

To their reduction, the scan revealed that the chick inside was doing simply advantageous. The condor chick even began “pipping” – one of many early phases of breaking via the shell. The crew returned the egg to its nest, the place its mother and father helped the younger chicken hatch on the morning of March 16. The crew named the chick Emaay (pronounced “eh-my”), a phrase for “sky” from the language of the Kumeyaay, an Indigenous folks of California.

The hatch of the brand new chick, whose intercourse shouldn’t be but decided, marks a notable milestone for the species, which narrowly evaded extinction. The chick’s father, Xol-Xol (pronounced “hole-hole”), was one among simply 22 condors surviving within the Nineteen Eighties that was introduced into the breeding program. “It’s form of like a full circle second,” says Willis.
