In an extraordinary discovery, a bird displaying both male and female characteristics has been spotted in Colombia. The bird, a green honeycreeper, showcases an extremely rare condition known as gynandromorphy, where one-half of its body has male traits and the other half has female traits.
This is only the second time such a bird has been recorded, with the first sighting occurring over a century ago. Gynandromorphy is rare in birds far less common than in insects or crustaceans.
In the case of this honeycreeper, the bird’s plumage is split between the green hue typical of females and the aqua-blue shade seen in males. The unusual bird was initially noticed by an amateur birdwatcher, whose observation piqued the interest of researchers from the University of Otago in New Zealand.
After further study, scientists confirmed that the bird’s split-color pattern reflects its dual-sex nature. While female honeycreepers are green, males are typically blue, but this unique individual has both colors equally distributed, setting it apart from typical honeycreepers.
There was initial speculation that the bird might be a young male due to the irregular pattern of its feathers. However, after being observed for nearly two years, the bird reached adulthood while maintaining its distinctive appearance.
Bilateral gynandromorphy, responsible for the bird’s appearance, occurs due to an error during egg development, leading to double fertilization. As a result, one side of the bird’s body develops female cells while the other develops male cells.
While this condition is more frequently seen in species where males and females have noticeably different appearances, sightings in birds remain extremely uncommon.
The first report of a gynandromorph green honeycreeper was over 100 years ago, making this new discovery particularly significant for ornithologists.
The bird was observed feeding on fruit left by a local resident, behaving similarly to its single-sex counterparts. Despite its striking appearance, it seemed to adapt well to its environment. However, researchers noted that it exhibited cautious behavior while feeding, possibly due to challenges in social integration with other birds.
As scientists continue to study this rare specimen, it highlights nature’s fascinating complexity and diversity. The honeycreeper’s dual-sex traits offer a glimpse into the many wonders still waiting to be uncovered in the natural world.
