Police helicopter crashes onto Glasgow pub
On the bird strike theory I accept that the air intakes are design to prevent ingestion. A Starling murmuration is more than a flock and can number several thousand smallish lightweight birds. I accept that this is an unlikely cause. However, I would draw the attention to AAIB bulletin 9/2008 relating to a similar type. The cause if the accident was not determined but the pilot observed a bird strike sound prior to power loss and Autopilot disengagement. Assessing a twin turbine failure he elected to autorotate ending up short of North Weald I a field. In that case the A/c was at 125kts in the cruise and transiting the Stansted Zone. It make interesting reading even if the cause/ circumstances are not similar.
