Scientists have captured on video an especially uncommon hen with male colors on one half of its physique and feminine plumage on the opposite half, shedding extra gentle on androgyny within the animal kingdom.
The uncommon inexperienced honeycreeper hen was noticed on a farm at a nature reserve close to Manizales, Colombia, researchers say.
It had aqua-blue feathers on one half and yellow-green plumage on the opposite with a transparent boundary within the center.
Typically males of the species have vibrant blue feathers and a black head, whereas females are grassy inexperienced throughout, scientists say.
The hen’s uncommon colouration is believed to have been brought on by bilateral gynandromorphism – a uncommon cell division error which creates an egg that permits for fertilisation by two completely different sperm.
“The bird exhibited typical male plumage on its right side and female plumage on the left,” scientists famous, including that its inner organs have been additionally seemingly divided down the center into female and male.
However, scientists couldn’t affirm this by sight alone.
“Whether the internal organs of our bird were also bilaterally gynandromorphic is impossible to tell,” researchers stated.

They studied the uncommon hen for a interval of 21 months because it returned to feed on the recent fruit and sugar water overlooked each day by the house owners of the Colombian farm.
This is just the second report of a hen with bilateral gynandromorphism, with the earlier one over a century in the past, and the primary time the phenomenon has been captured on digital camera.

The hen additionally appeared to attend for different birds to go away earlier than approaching, the scientists from Whitehawk Birding and Conservation in Panama say.
“In general, it avoided others of its species, and the others also avoided it; it seems unlikely, therefore, that this individual would have had any opportunity to reproduce,” researchers wrote within the Journal of Field Ornithology.
Such instances of bilateral gynandromorphism are extraordinarily uncommon within the animal kingdom, beforehand seen in animals like chickens, songbirds, spiders, and lobsters.
“Our observations extended over an unusually long period (21 months) and are the first of a gynandromorph of this species alive in the wild,” scientists wrote.
They stated the hen in Colombia additionally differed from the one different documented case in a doubtlessly essential side. “Moreover, the bird we observed exhibited female plumage on the left and male on the right, the opposite of the previous case from over 100 years ago,” they stated.
