Genome sequencing has unraveled a fascinating adaptation in New Zealand's iconic and rare bird, the kākāpō. These majestic birds evolved an incredible survival strategy to evade their predators – they changed their plumage colors.
New Zealand, being home to an array of wildlife, is especially famous for its beautiful but endangered bird species. The kākāpō stands out as the heaviest parrot in the world and is known for being nocturnal, flightless, and possessing a unique and strong sense of smell.
Although it has no natural defenses due to being flightless, research now suggests the evolution of distinct plumage colors enabled this vulnerable species to thrive amidst the presence of fierce predators. To evade birds of prey back in time, kākāpō needed to transform into an unseen creature – hence the variety in colors which undoubtedly made them camouflaged against the striking backdrop of their native New Zealand.
Historically known for being the victims of extinct birds of prey, eagles especially preyed on these rare parrots, posing a significant threat to their survival. Consequently, different varieties of the kākāpō emerged with unique color patterns, blending in an agile effort to assure their survival amidst the rapidly increasing predators that New Zealand was said to witness back in those times.
According to genome sequencing, this unusual transformation in appearance illustrates a remarkable, clever adjustment in nature. New Zealand's beautiful yet evolving landscape was once shelter to the largest ever eagles known today – the Haast's eagles. After intense eradication of threats and hunting, New Zealand started on the path of protection in preserving their wildlife and moving them away from the risk of erasure from nature.
Thanks to extraordinary advances in biotechnology and wildlife protection programmes, kākāpō populations in New Zealand are thriving today. Though on one hand we observe massive growth in this New Zealand species, on the other hand one also questions these biotechnological advancements as potential tools of reducing wildlife to more manageable fragments thereby keeping nature from thriving as naturally it should, ultimately, safeguarding Earth, for the people to enjoy both urban cityscapes and nature, safeguarding our future.
