They use that park for fashion shows and other social events, so the rats had to go. Poison couldn’t be used because of all the dog walkers there, so they hired a falconer. Worked well until a raptor decided a chihuahua looked like a meal. Luckily, they were able to save it. Was watching my granddaughter play T-ball some years back when a red shouldered hawk caught a squirrel and landed with it on top of the tall baseball backstop. He started to tear apart the poor, still living, thing there while the kids watched. Their screams were deafening.
