The female seemed more interested in having her breakfast, when she was approached by the male in Lake Clark.
Ex-civil servant Greg Morgan witnessed the scene on a trip to the northwest US state in June.
He said: “At low tide, where we were in Lake Clark the mudflats are exposed, and the bears see the clams as a great food source at this time of year.
“It coincides with mating season.
“We had seen this mother before and she had quite old cubs. While she was digging for clams, a large male had other ideas and started pursuing her.”
Amateur photographer Greg, 44, who lives in Walthamstow in London, visited Alaska to capture images of coastal brown bears.
The enormous state is home to roughly 98 per cent of the country's population of the species.
Greg took the photos in the late morning on June 21, and continued: “In the end the female ran off, and afterwards the male just had a lie-down on the mud.
“Another day he might have got more lucky, but not on this day.”
