Kestrels and kingfishers perform amazing maneuvers, hovering over land and sea. But as impressive as the hovering of a kestrel or kingfisher may be, these birds are mere dabblers in this particular talent. It is only in hummingbirds that nature has structured the wings in such a way that when in motion they act like a perfect lifting rotor. Their pointed wings do not flap and glide as other bird wings do, but propel them through the air by moving up and down, up and down, at a furious rate of 70 times a second. After feeding at a flower they can fly backward, climb vertically, tun at lightening speed, and come to a sudden standstill in midair. Hummingbirds have been known to fly up to speeds of 60 miles per hour in a tail wind.s No bird of prey even attempt to catch a hummingbird in flight.

Hovering is a demanding but useful ability used by several species of birds (and specialized in by one family). Hovering, literally generating lift through flapping alone rather than as a product of thrust, demands a lot of energy. This means that it is confined to smaller birds; the largest bird able to truly hover is the Pied Kingfisher, although larger birds can hover for small periods of time. Larger birds that hover do so by flying into a headwind, allowing them to utilize thrust to fly slowly but remain stationary to the ground (or water). Kestrels, terns and even hawks use this windhovering.
The Ruby-throated Hummingbird can beat its wings 52 times a second.Most birds that hover have high aspect ratio wings that are suited to low speed flying. One major exception to this are the hummingbirds, which are among the most accomplished hoverers of all the birds. Hummingbird flight is different to other bird flight in that the wing is extended throughout the whole stroke, the stroke being a symmetrical figure of eight, with the wing being an airfoil in both the up- and down-stroke. Some hummingbirds can beat their wings 52 times a second, others do so less frequently.

I was told by a falconer that the Kestrel was the only bird that can truly hover. It is more to do with the wing-beat than anything else. Supposedly, a Kingfisher is actually still in full flight whereas a Kestrel's wing-beat kind of just flickers and the bird stays aloft. If you have the chance, just watch one and you'll see the difference.
This is what I was told anyhow and it seems to make sense.

Can you confirm that the only bird that hovers is the kestrel?
