The landfills afford the opportunity to study these birds very closely and for prolonged periods. The "gull season" starts in mid October with the arrival of juvenile Thayer's, Kumlien's Gulls and Great Black-Gulls as the season progresses we see start seeing more advanced birds and usually in November the arrival of Glaucous Gulls. Ring-billed Gulls thin out by early November with stragglers mostly along the St. Mary's River until the New Year. By Christmas the gull flock has been reduced to less than 1000 birds but with a higher percentage of white-winged gulls especially Glaucous. By February a small handfull of Herring Gulls and an occasional Glaucous remain.
I am very keenly interested in bird photography. I have a large and growing collection of gull photos which I hope to share via this blog. I am learning ongoingly the values and pitfalls of photography in regards to gull identification. I hope to use this forum to voice my various musings on gull identification and related issues with illustrative photographs.
