Bird 2 with one Herring and other Ring-billed Gulls at various angles, showing intermediate size, darker mantle, and duller yellow legs than RBGU
Detalles de la observación
Continuing smaller bird with darker upperparts (first seen July 26). With two juvenile again today. Witnessed adult feed young and even fight off a third, larger juvenile that walked up during - good evidence that the first feeding observation was not a fluke, that these are offspring.
