Sparrowhawk frenzy

had plenty of sightings of Sparrowhawks over the last few weeks with the adult male and female putting in many attacks on next doors pigeons and Collard doves.I have only seen the young male once since last month but the young female is a monster.
  I have seen it hit at least 2 pigeons over the weekend and fail to kill.Yesterday Ann from next door came running round saying there was a pool of blood in her garden and there was a dead bird in the tree.Sure enough a beheaded pigeon was hanging upside down dripping blood all over her nice new flaggs.Apparantly the Sparrowhawk had got the pigeon stuck on its foot and could not get it off until it flew headlong into the tree and this freed it from its talons.It returned 3 hours later and took the beheaded carcass off for another feed.
 Today it was in my garden with a very large feral pigeon pinned to the lawn taking large bits of feathers out of its breast,suddenly the pigeon broke free and both birds flew off and hit the car feathers flying in all directions.The sprk chased the pigeon under the car running along the path.The pigeon nipped round the front wheel and escaped.i saw the sprwk hunting high over the cricket pitch a bit later so it was still hungry......
