I believe that the decrease in gull species is a consequence of the dump closing. Bonaparte's, that forage in the Water Quality Control Plant, will sometimes take a break and bath in the pond in the hundreds. But the rare gulls that showed up in the Duck Pond were there only in the heyday of the dump.
I don't know why the scaup disappeared, I've noticed that as well.
