Kiwis have a fairly long beaks, but technically they have the shortest beaks of all birds. There’s a very funny reason for that.
Kiwis can’t see too well. However they have an exceptionally good sense of smell, thanks to their nostrils which are at the tip of their beaks.
According to another research done recently, Kiwi beaks have specialized sensors at the tip which help them to sense tiny vibrations. Combining both the exceptionally good sense of smell and the ability to detect minute vibrations using their beaks, kiwis are able to find creepy crawlies moving under a layer of mud.
Now, they have long thin beaks, physically. And at the end of the beak there are nostrils.
Officially the convention to measure the beak of a bird dictates that the measurement be done from the end of the tip to the nostril. And since Kiwis have nostrils at the tip, the distance from the tip of their beaks to their nostrils is very less (negligible). That distance is also, technically, according to the convention, the length of their beaks.
So, Kiwis officially have the shortest beaks among all birds, even if they physically have fairly long beaks.
