The non adult dropped in only briefly and quickly returned to his rooftop perch, no matter, the other two where willing to stick around.
Iceland number 2, now also absent seemed to prefer staying on the water with the black headed gulls rather then perching overhead on the street lights.
Number 3, still seems to be frequenting the area, seemingly he prefers staying overhead on the overhead lights but occasionally he comes down and swoops out over the river when one of the regular bread feeders come along. Since it only gives about a 30 second window before returning to its perch it is actually quite hard to capture with the camera.
A surprise adult ring billed gull showed up for a few minutes. I had never seen one this far from the docks before. It’s not the same bird I found at the Atlantic pond since this one had bright yellow legs instead of greenish.
