While spectators politely observe the quiet signs held up by stewards as players take their shots, the seabirds — milling above the famous yellow leaderboard at the 18th hole — make an impressive racket.
As they circle for food, the fear of being the unfortunate landing spot for their waste is a constant anxiety, with several staff and fans already falling foul.
Yet in the skies over the nearby food court and grandstands, not a single gull in sight. This is the result of some nifty recruitment by event organizers: four birds of prey.
Fans navigating the Old Course across the week will grow accustomed to seeing a pair of hawks — a red-backed and a Harris — an Indian eagle-owl and a tawny eagle.
Named Enya, Nailer, Sage and Fearnley respectively, the guardians perch on their handler’s gloves to ward off seagulls from the picnic area, as well as the 1st and 18th grandstands.
The birds come from the nearby Elite Falconry — hired for the event — with handler John on lunchtime duty for Thursday’s opening round after a flurry of seagull activity around the first tee during the early morning.
“Without us here, the seagulls would literally be divebombing people trying to steal their food,” John told CNN Sport.
With seagulls not a typical cuisine of the four birds of prey, they don’t fly around the course and instead sit calmly on their handler’s glove for the duration of their watch, their presence alone enough to stave off the unwanted visitors.
Golf is not the only sport to call on the aid of birds of prey at events. At Wimbledon, Rufus the Hawk has long been a local tennis hero for his efforts at the All England Tennis Club.
In keeping the courts free of pigeons — whose pecking at grass seeds can interrupt play at the tennis grand slam — Rufus has become something of a local hero in southwest London, with one super-fan dressing up as the hawk for the 2017 championships.
