Condors Can Reproduce Asexually

0 27

A study by conservation scientists at the San Diego Zoo Wildlife Alliance found that condors can reproduce without mating.  California condors is a critically endangered species. It is also one of the world’s rarest bird species, but its population is increasing.

During a routine analysis of biological samples from the California condors in the zoo’s breeding program, the scientists found that two condor chicks had hatched from unfertilized eggs.

Scientists confirmed that each condor chick was genetically related to its mother but neither bird was genetically related to a male. The two birds represent the first two instances of asexual reproduction, or parthenogenesis, to be confirmed in the California condor species.

“This is a very rare discovery because it’s not well-known in birds in general. So it’s known in other species, in reptiles and in fish, but in birds it’s very rare, in particular in wild species,” said Cynthia Steiner, associate director for the alliance’s conservation research division.

It was also confirmed that both female birds were continuously housed with fertile male partners and had already produced chicks while paired with a male. Asexual reproduction has never before been confirmed in any avian species where the female bird had access to a mate.

Both chicks were underweight when they hatched. one of it was released into the wild and died at the age of two in 2003, while the other survived for eight years in captivity and died in 2017.
