Gulls waking towards an arriving car near Lowe's in Bristol TN Driving in south Bristol Tennessee quickly reveals a nice flock of Ring-billed Gulls soaring over buildings, perched on utility poles and standing in parking lots. It is amazing that these birds show obvious signs of being urban gulls. It is not just that they are in an urban setting. There is more to it than that. It seems that we have two distinct populations of Ring-billed Gulls wintering in Sullivan Co., TN and Washington Co., VA. Let's call them "urban gulls" and "rural gulls". Here is the evidence. Much of it has been learned from trapping and banding Ring-billed Gulls in urban settings but that was not a necessary requirement in order to think this. It is a process that we often share with other birders: don't just ID birds....think about why they are were they are and when they are there and exactly what we are seeing -- stand and think. A thousand of such gulls may be wintering on impoundments in Sullivan County. Hundreds are frequenting the urban parking lots. Sam Cross with gull in 2004 Trapping and banding in winter taught us that urban gulls are so accustom to people they will actually walk up to a car driving into a parking lot to see if food will be tossed to them or if the remnants of a burger or whatever will be discarded from a window. They are not shy and come very close. These parking lot birds land on McDonald's golden arches just as soon as they arrive in town in mid-winter as they are driven in by the freezing waters and snow storms in the north. They do not appear to come to us from the ocean. They are thought to be coming in from the Great Lakes and interior Canada. The web site Migratory Birds of the Great Lakes reads: Highly tolerant of humans and human-impacted habitat, Ring-billed Gulls can be found around landfills, farm fields, mall parking lots and golf courses in addition to coastal beaches, islands and breakwaters. The gulls on our more open waters and impoundments are not tolerant of humans and do not let you approach them on foot or by boat. They are very wary. It appears they do not have much human contact at any season of the year. Humans do not mean food. They mean danger. Both populations are difficult to trap. Urban gulls do not fly under utility lines unless hard pressed to escape. They do not fly under anything. They do not fly under trees. They perch on rooftops and walk on driveways and sidewalks where they are not facing danger. The map at the left, borrowed from an online website, shows the breeding range of the Ring-billed Gulls in red. Note that these inland gulls are hardly "sea gulls" by the normal stretch of the imagination. They are actually freshwater gulls. The light blue shows the wintering range over much of North America. Some breed and winter around the Great Lakes, as shown in purple. Do Ring-billed Gulls perch on utility poles and feed in the parking lots of McDonald's, Wal-Mart and so many other look-alike retail places on both their breeding grounds and wintering grounds -- there and here ? Do they recognize that McDonald's golden arches advertise fast food for not only humans but Ring-billed Gulls ? They will fly between cars and walk among traffic in fast food lots to get any crumbs and scraps of food. They seem to do that the first day they arrive here for winter. It does not appear to be something they have to learn and get up their nerve to handle. They already know all about these signs and light poles to perch atop. Are the birds which frequent our lakes and such by the thousands from the prairie areas of Canada and northern states ? Do they not only nest and feed in fields and such well away from much human activity but keep their distance here also ? Does this give us a hint that we have populations from both of these areas -- urban and rural gulls ? Let's go birding . . . . Wallace Coffey Bristol, TN
