Glaucous-winged Gull at Vacation Isle, continuing bird?

Mid-afternoon Saturday there was an adult Glaucous-winged Gull at the northeast tip of Vacation Isle in Mission Bay.  Large, pink-legged, dark-eyed gull with light gray mantle and wings uniformly the same color as mantle.  Based on ebird, looks like this may be a continuing bird; although there are have been no reports in the area since September 1.
