The adult male, a regular at Romsey Abbey, was killed just outside Romsey while trying to retrieve dropped prey on Thursday, March 12.
Born at St Mary’s Church in Andover in 2020, he had been at the abbey for the past two years.
Keith Betton, Chair of Hampshire Ornithological Society, said: “We were sad to hear that our regular adult male Peregrine died in a collision with a vehicle just outside Romsey.
“He had dropped a prey item and was trying to retrieve it when the collision occurred.
“He was born at St Mary’s Church, Andover in 2020 and came to the Abbey two years ago when his nesting attempt with the female ended when their nest was affected by rain.
“Last year they nested on the side of the abbey in a gully.”
The peregrine had begun showing aggression towards one of his 2025 male offspring, who may now become a presence at the site.
Mr Betton added: “Now he has died it is possible that the young male will stay around to take his father’s place.
“He is too young to breed until 2027, but if his mother is already carrying eggs and continues to lay them, he may well take on the role of a helper. We will keep you informed as things progress.”
