This gull's age can be judged by the intensity of the red on their bills--the brighter the red, the older the bird (Wikipedia). I assume this bird is relatively young. Obviously this gull has adapted to urban environments. They scavenge and thus thrive at malls and garbage dumps. At least twice, Silver Gulls have been seen in North America (in New Jersey and New York) but these birds are assumed to be escapes from captivity. Normally the species is restricted to Australia and New Caledonia.
