A biker who died after being struck by a pheasant on the A6116 near Lowick has been named by police.
Police have formally identified the victim as 54-year-old Christopher Adams, from Leigh-on-Sea, Essex.
Mr Adams, who was riding a black Kawasaki motorbike, was travelling along the A6116 from Corby towards Thrapston when he was struck by a pheasant at about 4.05pm on Saturday.
The impact caused him to swerve into a lay-by and hit a kerb.
He was airlifted to University Hospital in Coventry with serious injuries, but later died.
Police are re-appealing for witnesses to the accident and would particularly like to speak to the driver of a silver Seat Leon who stopped at the scene before police arrived.
The Seat is believed to be a 2002/04 model, driven by a white man, approximately 6ft, who wore jeans and a grey T-shirt.
Police believe he may have witnessed the accident and are urging him to contact them.
Witnesses to the collision or anyone with information about it is asked to call the Drivewatch Hotline on 0800 174615 or Northamptonshire Police on 101.
