Mercedes-Benz reveals an incredible One-Eleven concept SUPERCAR with gullwing doors.They found this wasn't unique to birds in the aviary, but had only witnessed it directly in use among those cockatoos. ![]() The fact only two of the 15 birds made use of tools suggests it isn't innate in the species, but rather unique to a handful of creative individuals. The middle tool was closest to a spoon, which allowed the birds to dig into the pit and drag out the seeds to later consume.įinally the thickest tool, not used in every case, was treated like a wedge that they could use when prying the pit apart at the natural crack to get the spoon inside. The thinnest of the three wooden tools were carved to be sharp, almost knife-like, and let the bird pierce through the pit's coating. They grabbed the tools once the birds had finished and created 3D models to understand what they were used for and draw parallels to human-created tools. 'After I gave them the fruit, I looked back and was just blown away,' O'Hara told New Scientist, adding 'they definitely knew the fruit, and they knew what to do with it.' The older male birds then used their tongues and beaks to craft slivers of wood into three different sizes and thicknesses - creating cutlery that they then aimed with their beaks to jab into the seed pit of the mangos. O'Hara and colleagues watched on in astonishment as they also cut whole branches to dig into the remaining stump and pull out pulpy wood. However, two of the older males grabbed the mango, flew into a nearby tree and began stripping wood from the branches using their beaks. One day the researchers offered the 15 birds in their aviary the fruit to eat, and 13 of them dug in with their beak as expected to eat the fruit itself - not the seeds. It is toxic to humans but a delicacy to the parrots. They are the only known species on the island to eat a hard-pitted fruit called sea mangos. To better understand these small white parrots, the team observe them in a large outdoor aviary on the islands, close in appearance to their natural habitat. ![]() 'The presence of flexible use and manufacture of tool sets in animals distantly related to humans significantly diversifies the phylogenetic landscape of technology and opens multiple avenues for future research.' 'Furthermore, these observations demonstrate how a species without hands can achieve dexterity in a high-precision task. 'The use of a tool set in a non-primate implies convergent evolution of advanced tool use,' researchers from the University of Veterinary Medicine Vienna, explained. Goffin's cockatoos don't rely on the ability to survive, but two out of 15 temporarily captive birds were seen making the tools, and further evidence was found in the wider jungle of the Tanimbar Islands, Indonesia. Through an outdoor aviary, scientists spotted cockatoos stripping out branches and turning pieces of wood into cutlery to dig into sea mangos. However, it is very difficult to record tool use in natural settings that don't occur throughout a species. This is because these cases emerged through creativity and intelligence. ![]() To unravel the origins of such complex behaviours, scientists set out to investigate instances where tool use isn't required for species' survival. The use of different tools to achieve a single goal is considered unique to human and primate technology.
