Poznámky

Bird 2 with one Herring and other Ring-billed Gulls at various angles, showing intermediate size, darker mantle, and duller yellow legs than RBGU

Podrobnosti k pozorování

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.
