The electronic replica condor egg was created by a 3D printer. It records sound, temperature, movement and other data critical to saving the species – one of the original animals included in the 1973 Endangered Species Act.
"We’ve never been able to get this type of information from inside of a California condor nest before," said Kelli Walker, the zoo’s senior condor keeper. "Knowing the precise conditions for rearing healthy chicks could be very useful to condor recovery efforts."
In 1982, only 22 California condors remained in the wild, according to the zoo. Five years later, the last condors were brought into human care in an attempt to save them from extinction. When the egg is in a nest box, the zoo said the equipment hidden inside measures turn rate, temperature and how often the egg is moved. It can also record audio of condor parents’ breathing and heartbeats while they take turns sitting on the nest.
