Crows will mob ANY bird of prey from merlins to eagles but need the high ground to do so .Birds of prey rarely engage in conflict as a damaged bird is a dead bird .

Walshie sent me a link to the buzzard he seen .......   https://www.google.co.uk/search?q=sparrow&prmd=ivn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwijnojMi5_UAhXMKcAKHSxQDLcQ_AUICSg

As far as I am aware the only bird of prey to truly hover like a hummingbird is the kestrel other birds of prey need thermals to hold them in place and beat their wings only to adjust movement or catch a better thermal .......

Hovering[edit]
220px-Calypte_anna%2C_San_Francisco.jpg
The ruby-throated hummingbird can beat its wings 52 times a second.

Several bird species use hovering, one family even specialized in it. True hovering by generating lift through flapping alone rather than by passage through the air demands a lot of energy. This usually confines the ability to smaller birds, but some larger birds such as a Kite [12] or an Osprey [13][14] can hover for a short period of time. Although not a true hover, some birds remain in a fixed position relative to the ground or water by flying into a headwind. Kestrels, terns and even hawks use this wind hovering.

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 the most accomplished hoverers of all the birds. Hummingbird flight is different from other bird flight in that the wing is extended throughout the whole stroke, the stroke being a symmetrical figure of eight, with the wing producing lift on both the up- and down-stroke. Some hummingbirds can beat their wings 52 times a second, though others do so less frequently.

We know that, the point is; is that kestrels can hover, buzzards can't (in the same way) ;)

 

yes they can

I would be interested to see a clip of a buzzard preforming a sustained hover the same way a kestrel does ......

It wouldn't be for as long, but they can hover in the same way, both different from the humming bird. I've had a goshawk hover over bramble in the middle of dense woodland waiting for a flush, obviously unsustainable, but add a bit of wind & you've got your kestrel & to a lesser degree a buzzard.
