The fastest bird is the hiking falcon. But he can not "fly on the spot".
The bird that can fly "on the spot" is called Kolibri.
I believe that would be the vibrating falcon
In the dive, the hiking falcon is the fastest bird and reached more than 300 km /h.
The Kolibri, which was named here, is certainly not one of the fastest birds, but has the fastest wing strike (up to 200 wing beats per second) and can fly on the spot.
