Continuing bird. Thanks to Bill Rowe for finding and reporting this bird. We found him flying around Teal Pond late in the afternoon for quite a bit until he took a rest across from it out in Ellis Bay, where we took some photos. (I'll add a video we digiscoped in a sec, too.) Bill Rowe's description of the bird is perfect so I'll repeat it here and add a little note afterward. Bill's description is thus: "juvenile gull smaller than the surrounding Ring-billed Gulls; upperparts were overall brown, extending onto the breast and flanks; the breast and belly were lighter; dark legs and bill; forehead light to the base of the bill; broken oribital ring (crescents); back and wing covert feathers had wide pale margins, creating a strong scaled look; white tail with thick dark edge at the tip; dark wing tips and dark edges to secondaries;" I would also add that how you know this first year bird is not a first year Franklin's Gull because a first year Franklin's Gull would have a smaller and straighter bill not the long drooping one you see on this Laughing Gull, a Franklin's would have a more extensive cleaner blackish half-hood whereas you can barely make out even a hint of a hood on this first year Laughing Gull, a Franklin's would also have a more whitish neck, an incomplete tail band, a more whitish breast and paler underside to the primaries. This Laughing Gull obviously has a more gray-brown hindneck and breast as well as mottled darkish underwings. Here's a short video we made of him today:
