First Winter Thayer's Gull - 2/10/12. "This is a dark Thayer's Gull in worn juvenile plumage which resembles a dark juvenile (Northern) Herring Gull. The bill is small and narrow. A line formed by a ruler held along the culmen going back through the lores does not approach the top of the eye but rather seems to go through the middle of the eye. P6 and P7 have pale tips but the tips of P8,9 and 10 are worn off. The scapulars are juvenile but have largely lost the pale tips as well. There is still a lot of white edge spotting remaining on the sides of the juvenile scapulars. "  (Thanks to my friend Kevin for his insights)
