Common buzzard are also becoming common again. I've had a nesting pair not far from my house and the mewing, soaring and thermal-riding of the parents & offspring are a pleasant sound and sight.
Regarding mobbing of avian predators by smaller birds - it happens a lot. I once witnessed a goshawk being chased by several vocal blackbirds and have seen a pair of spars (sparrowhawks) being mobbed by feeding sand martins. Spars are quick and maneouverable in places where there is tree cover, but are fair game for the even quicker martins when caught out in the open. The spars retreated to their speciality habitat. Crows also mob buzzard, even though the buzzard isn't necessarily a direct predator. However, buzzard (and kite) are direct competition. Seeing a buzzard getting fed up with the mobbing is another good sight - a quick 'flip' upside-down, talons skyward and the crow in pursuit beats a hasty retreat.
Rumour from a year or two back was that kite were spreading toward this part of the country. I've not seen one yet, but fingers crossed.
