ALBAWABA - A remarkable discovery left experts astounded in Colombia. A one of kind bird showcasing bilateral gynandromorphy, was spotted in a nature reserve in Villamaria. Bilateral gynandromorphy refers to a condition in which one side of an animal exhibits male characteristics while the other side displays female characteristics.
This unique bird, a male Green Honeycreeper, showcased the typical blue plumage and black head on its right side, while its left side was adorned in a beautiful grass green.

The first observer of this extraordinary bird was amateur photographer John Murillo. In late 2019, Murillo caught sight of the bird through his camera lens as it landed on a feeder to enjoy a meal of bananas and grapes. This sighting initiated a year-long observation period, during which Murillo and experts examined the bird extensively, although they were unable to capture it.
The findings of Murillo and a group of bird scientists were published last month in the prestigious Journal of Field Ornithology.
This publication marks the recorded first observation of bilateral gynandromorphy in a living Green Honeycreeper, scientifically known as Chlorophanes spiza. The article suggests that the phenomenon in birds occurs due to a meiosis error during egg division, followed by fertilization by separate sperm.

The researchers were unable to determine if the bird's internal organs also showcased gynandromorphy or if it was fertile. However, this exceptional discovery has provided valuable insights into the field of avian biology.
Murillo, expressing his gratitude for witnessing this unprecedented event, explained the bird's peculiar behavior. The bird seemed to prefer the company of humans rather than its species, and it was often seen alone at the feeder.
Sadly, due to its exclusive nature, experts believe that this remarkable bird will not find a mate and may eventually pass away, making it an unparalleled phenomenon that the world has been fortunate to observe.
