Poznámky

Bird 2 with Herring Gulls at various angles, showing smaller size, darker mantle, down turned gape, dark eye but with iris pale enough to discern

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.
