World smallest parrot caught on film...

I always thought that Parrotlets were the smallest species of parrot, but I guess not. These little buff-faced pygmy parrots weight in at less than half-an-ounce. That's tiny. This is from BBC news:

The world's smallest parrot has been filmed in the wild for the first time by a BBC expedition.
The team, filming in Papua New Guinea for the programme Lost Land of the Volcano, caught two of the buff-faced pygmy parrots on camera.
On average, buff-faced pygmy parrots (Micropsitta pusio) are not much bigger than a human thumb, standing less than 9cm tall and weighing 11.5g (0.41 oz).
