Credit: John Murillo<\/figcaption><\/figure><p>Bilateral gynandromorphism is believed to be caused when a female bird\u2019s egg develops two nuclei, and is then fertilised by two different sperm, known as double fertilisation. The resulting offspring has female cells on one side of its body and male on the other. As well as the split in plumage, the bird also has an ovary on the female side and a teste on the male side, and could theoretically mate as either.\u00a0<\/p><p>It is much easier to spot bilateral gynandromorphy in species that are sexually dimorphic \u2013 where the male and female look different.\u00a0<\/p><figure class=\"wp-block-image size-full\"><figcaption class=\"wp-element-caption\">It is much easier to spot bilateral gynandromorphy in species that are sexually dimorphic, such as the green honeycreeper.
