While looking through some old video footage I came across a Gull that I took in Golden Gate Park, San Francisco. I remember that it caused some head scratching at the time. The footage was taken in May and the only other Gulls present were Western Gulls. This bird was smaller and appeared to have an injured leg. The plumage appeared bleached and the primaries were not black. Do you think it is a small "smithsonianus" or something else? Any comments would be welcome. I apologise for the quality of the videograbs.
