The 25-year-old brothers are the first known twins to become ghillies in Scotland working for the same family.
Earlier this year, Alastair started work on Dinnet and Kinord Estate as a full-time ghillie on a beat of the river Dee owned by Edward Humphrey.
Following the retirement of the ghillie at Aboyne Castle, which is owned by Edward’s brother, Simon Humphrey, Alastair’s identical twin brother William has landed the job of ghillie on that beat.
Edward Humphrey said: “There cannot be many instances of twins working not just for the same family but in the same profession.
“The fact that they are 25 years old and are keen to develop their careers on one of the top four salmon rivers is great news.”
“It’s been great for the estate as they have brought a real enthusiasm and dynamism to the job.
“The only problem is when you bump into one of the them on the riverbank sometimes it is difficult to tell which one you are talking to.”
The brothers Peake, lifelong anglers, started flyfishing in Royal Deeside from a young age with their grandfather, Alan Smith, and developed a passion and love for the great river.
Alastair Peake said: “My brother and I are devoted to fishing and there is nowhere better than the Dee.”
“We’ve worked on some great salmon rivers and, frankly, it is a wonderful job to have.”
The brothers both enjoy being colleagues and William noted the advantages of having his twin with him on the river.
He said: “It’s great fun working on adjoining beats and there’s always the chance that if something goes wrong we blame each other.”
Alastair and William are leaving for New Zealand this week before returning to the Dee early next year.
