These little guys normally see you before you spot them. But go into an area with a good horse and when they start to circle you to try and knock you....start kicking! I actually Ko'd one at random and tamed her up. Actually a beautiful baby I named Fifi, a suitable name for an ankle-biter! XD
Many confuse these with the archaeopteryx. The micro raptors have singular head crests, whereas the archaeopteryx only have head feathers. The micro also has a flat cluster of feathers on the end of its tail, archaes have feathers along each side instead of at the end.
