El Condor pasa

Female California condors reproduce through parthenogenesis even if there are males around?! The ultimate feminists? From Wiki and a science journal. 

>>>In 2021, the San Diego Zoo reported that they had two unfertilized eggs from their California condor breeding program hatch. This is the first known example of parthenogenesis in this species, as well as one of the only known examples of parthenogenesis happening where males are still present.

Parthenogenesis

>>>Parthenogenesis is a relatively rare event in birds, documented in unfertilized eggs from columbid, galliform, and passerine females with no access to males. In the critically endangered California condor, parentage analysis conducted utilizing polymorphic microsatellite loci has identified two instances of parthenogenetic development from the eggs of two females in the captive breeding program, each continuously housed with a reproductively capable male with whom they had produced offspring. 

>>>Paternal genetic contribution to the two chicks was excluded. Both parthenotes possessed the expected male ZZ sex chromosomes and were homozygous for all evaluated markers inherited from their dams. These findings represent the first molecular marker-based identification of facultative parthenogenesis in an avian species, notably of females in regular contact with fertile males, and add to the phylogenetic breadth of vertebrate taxa documented to have reproduced via asexual reproduction.
