Deceased
Also known as Ron of the Notch Boys · The Smallest Notch Son
c. 2005 – 2016
Born in Musiara Marsh area, Masai Mara, Kenya
Ron was a male lion of Kenya’s Masai Mara and one of the five sons of the legendary Notch. He was born into the Marsh Pride, the pride made famous by the BBC’s Big Cat Diary, while his father was its king, and he grew up to be one of the six males of the Notch Coalition, the rare father-and-sons alliance that ruled much of the Mara for about a decade.
When Notch was driven out of the Marsh Pride around 2007, Ron and his brothers, Notch II, Mighty Long, Caesar and Grimace, were only about two and a half years old. They left with their father and, as they grew, took over pride after pride, including Fang’s River Pride at Rekero, the story told in Disneynature’s African Cats. Ron is often described as the closest brother of Caesar, and lion followers remember him as the smallest of the brothers but one of the boldest.
After Notch died and Grimace vanished in 2013, Ron, Caesar and Notch II carried on as a trio, moving south from the Rongai pride area towards Lookout Hill and the Sand River near the Tanzanian border. In mid-2016 Ron went missing and was never seen again. He is reported to have been killed by the Sand River males, a rising rival coalition, at about 11 years old.
The name given to him by guides and lion followers in the Mara. Who first named him, and why, has not been documented.
Used by photographers and guides to tell him apart from other Mara lions, including the younger male known as Ron II.
Lion followers reportedly described him as the smallest of Notch’s sons, though not the least bold.
Born in the Marsh Pride, one of five sons of Notch, the pride’s king.
Romeo and Clawed drove Notch from the Marsh Pride. Ron, about two and a half years old, left with his father and brothers.
Seen with his father and brothers in the BBC’s Big Cat Live.
The coalition took the River Pride at Rekero from Fang, the story told in African Cats. His brother Mighty Long disappeared.
The Notch males were reported to control five prides in the eastern Mara.
His father Notch died, and his brother Grimace vanished a few months later. Ron, Caesar and Notch II carried on as a trio.
The three brothers reportedly began moving south from the Rongai pride area towards Lookout Hill and the Sand River.
Reportedly spent most of the year in the south of the reserve, mating with the lionesses there.
Reportedly photographed with fresh battle wounds, guarding a hippo kill while his brothers slept nearby.
Went missing and was never seen again; reportedly killed by the Sand River males.
His brother Caesar died, leaving Notch II as the last of the original coalition.
After 2013 only Ron, Caesar and Notch II remained. Ron’s disappearance in 2016 is often seen as the start of the final chapter of the Notch Coalition.
Much of Ron’s life, including his death, is known from guides, photographers and lion followers rather than published research, so these details should be read as reports.
