Nigel Hewitt has dedicated thousands of hours to volunteering for the RSPB
A wildlife charity's longest serving volunteer has dedicated 60 years of his life to bird conservation.
Nigel Hewitt first volunteered with the RSPB in 1966 during a break from studying for his A levels when he helped to protect ospreys.
Hewitt, 77, has a special place in his heart for the cirl bunting, which was almost lost in the UK, and had helped manage their habitats at the Labrador Bay and Ashill nature reserves in Devon while also being involved in the red-backed shrike project on Dartmoor.
Fellow birder John White said: "His knowledge is unbounded. He loves it. He'll talk for ever about birds."

Hewitt showed the BBC around the reserve at Ladrador Bay near Shaldon and said the small finch-like cirl buntings, which were once common on farmland on southern England but are now on the conservation red list, "don't want to be very obvious".
He added: "They just want to quietly get on with producing young, feeding them in the nest and not being seen."
More than 1,000 pairs were recorded in the last national survey in 2016 and they are mainly found in south Devon, with a reintroduced population in Cornwall, the RSPB said.
Hewitt said: "They're a great little bird. Because we're saving this place specifically for cirl buntings, we're also creating habitat for lots of other birds."

Hewitt said he got the volunteering bug during "a wonderful time" helping Operation Osprey when he helped protect the first pair of ospreys to breed in the UK for more than 100 years.
"We were guarding the ospreys 24 hours a day, so we had schedules where we did different shifts on different days.
"We sat in a hide with telescopes and various hearing systems to protect them."
"Sadly, there had been numerous attempts by people to chop their nesting tree down and steal the eggs. I thoroughly enjoyed the task, and it was the start of 60 years of volunteering."
