Pink-breasted oakbeak turned out to be a bird with abnormal muation of the sexes

A strange bird was discovered by ornithologists in Pennsylvania. The pink-breasted oakbeak turned out to be a gynandromorph. That is the name of a unique anomaly in the development of a living organism where male and female genotypes and characteristics are combined . Males of pink-breasted oakbeaks traditionally pronounced red-pink feathers and black feathers on the wing. In females of the species of birds, they are yellow-brown.

The bird that was discovered, has both types of color. And it indicates that on the one hand, the bird is female, and on the other, it is male. It has a pink patch on the chest, red feathers on the wing, and black feathers on the right wing.


Surprisingly, that individual combines the characteristics of the male and female species. Annie Lindsay, a specialist from Powdermill Sanctuary, where the strange creature was discovered, says that her team was surprised to observe the strange bird that is half male and half female.

The bird is unique in that it does not suit nests and in spring, when the plumage acquires the brightest shades, its features will be extremely pronounced. And the line between masculine and feminine will become even more obvious. By the way, such representatives of the feathered world are extremely rare for the scientists.

For the first time, the ornithologists observed the similar anomaly about 15 years ago. But they were not sure if the bird could be classified as a gynandromorph. Such deviations in development are found not only in birds, but also in many species of animals, insects and crustaceans. In the case of the pink-breasted oak beak, the scientists suggest that its appearance was possible as a result of the fusion of two sperm and one egg that had two nuclei instead of one.


Then, both male chromosomes and female chromosomes could form in the egg, which ultimately led to the development of a bird with genotypes of both genders. The scientists do not know how the bird behaves in nature yet. There is also no data on whether the oakbeak can produce offspring.
